Thrips are small, slender insects belonging to the order Thysanoptera. They have fringed wings, and the adults feed by puncturing the outer layer of plant tissue, causing damage to crops and ornamental plants. Let’s learn some more about thrips and their characteristics.

There are two suborders of thrips: Terebrantia and Tubulifera. These tiny insects come in various sizes and colors, with many generations occurring throughout the year. Here are some features of thrips:

  • Adult thrips have fringed wings
  • They can cause damage to plants by puncturing their outer layer
  • Thrips reproduce quickly, resulting in many generations in a short time

Some common types of thrips include Western flower thrips, Onion thrips, and Citrus thrips. Although they can be destructive to plants, thrips also serve as a food source for predatory insects, contributing to the balance of the ecosystem.

In conclusion, understanding thrips helps you better manage and protect your plants from these tiny insects. So, keep an eye out for thrips and ensure the health and well-being of your garden or farm.

Thrips Life Cycle

Thrips go through several stages in their life cycle, starting with eggs. Adult females deposit their eggs into plant tissue, such as leaves or fruit.

The eggs hatch, and the emerging larvae actively feed on plant cells. This stage lasts for about a week, depending on factors like temperature and humidity.

Some key features of thrips life cycle:

  • Females deposit eggs into plants
  • Larvae actively feed on plant tissue
  • Non-feeding pupal stage before becoming an adult

After the larval stage, thrips transition into a pupal stage, which is a resting period. The pupal stage takes a few more days, after which they become adults. These adults then mate, and the cycle continues.

In greenhouses, most adult thrips are females, and reproduction without fertilization is common. They often gather in large numbers on the same leaf or flower.

It’s important for you to remember that the length of the thrips life cycle is strongly influenced by factors such as temperature and humidity. Keep these factors in mind while dealing with or trying to prevent a thrips infestation.

Thrips Diets and Feeding Habits

On Leaves and Stems

Thrips are tiny insects that feed on the outer layer of plant tissue. They puncture the epidermal layer and suck out the cell contents, causing stippling, discolored flecking or silvering of the leaf surface. You may also notice black, varnishlike flecks of their excrement on the leaves.

When they feed on your greenhouse plants, their damage can be visible on leaves, stems, and foliage. In high populations, thrips can even cause leaves to become distorted, curled or twisted.

Pollen and Flowers

Thrips are also found feeding on pollen and flowers of various plants, including onions, beans, and tomatoes. Their feeding results in the disruption of normal flowering processes, dropping of buds, and reduced fruit set. It’s important to check your flowering plants for any sign of thrips infestation.

Characteristics of thrips damage on flowers:

  • Fading or browning of petals
  • Twisted or deformed flowers
  • Pollen staining on petals

On Fruits and Vegetables

Thrips can cause damage to a variety of fruits and vegetables. For example, the greenhouse thrips can affect avocado fruits when a colony of thrips feed on the fruit in a group over an extended period of (25 thrips-weeks, for instance). The result can be a 0.75 inch diameter sunken area on fruit. Other vegetables that may be affected include tomatoes, beans, and onions.

To minimize damage caused by thrips on your fruits and vegetables:

  • Monitor and manage their population
  • Encourage natural predators

  • Introducing predatory insects to your garden
  • Applying appropriate insecticides when necessary

Remember that maintaining a healthy garden and keeping thrips populations in check can help minimize the risk of these plant diseases. Make sure to monitor your plants regularly and take action when needed.

Controlling Thrips

Using Insecticidal Soap

Insecticidal soaps can be an effective way to control thrips. These soaps can suffocate the insects and help you get rid of thrips. To use this method, follow these steps:

  1. Mix a solution of insecticidal soap according to the label’s instructions.
  2. Apply the soap solution to the affected plants, making sure to cover both the top and bottom of leaves.

Keep in mind that this method may need to be repeated multiple times for effective control.

Employing Biological Control

Another way to control thrips is by introducing beneficial insects that prey on thrips, such as pirate bugs, lacewings, ladybugs, and parasitic wasps. These predators can help control the thrips population, reducing the need for pesticides. Here are some examples of biological control methods:

  • Pirate bugs: These small insects can attack and kill a variety of thrips species.
  • Lacewings: These delicate insects are known to feed on thrips larvae.
  • Ladybugs: Ladybugs can also prey on thrips and help control their population.
  • Parasitic wasps: Certain species of wasps can lay their eggs inside thrips, killing them in the process.

You can release these beneficial insects in your garden or greenhouse to help control thrips.

Applying Pesticides

If other control methods aren’t effective, you may need to resort to using pesticides. Chemicals such as spinosad can be used for controlling thrips. However, it’s essential to use these chemicals responsibly and follow the label’s instructions to minimize negative impacts on the environment and non-target insects.

Here is a comparison table to help you choose the best method for controlling thrips:

Control MethodProsCons
Insecticidal SoapNon-toxic, eco-friendlyMight need multiple applications
Biological ControlNatural, reduces pesticide useRequires careful management
PesticidesFast acting, effectiveHarmful to non-target insects and plants

When deciding on a control method, consider the severity of your thrips infestation and the impact each method may have on your plants and the environment.

Thrips and Humans

Thrips can be a nuisance to humans due to their penchant for feeding on plants and potentially causing damage to crops. In some cases, they may also bite humans, although it’s not very common. These tiny creatures are often mistaken for other insects like whiteflies, mite eggs, or small moths.

When you encounter thrips, it’s essential to know their characteristics and habits to deal with them effectively. Here are some key features:

  • Tiny, slender insects with fringed wings
  • Feed by puncturing the outer layer of host tissue and sucking out the contents
  • Can cause damage to crops and plants
  • May vector viral diseases in certain circumstances

Thrips can be managed with a combination of methods such as biological control, use of insecticides, or proper cultural practices. For example, introducing natural enemies like predatory mites or parasitic wasps can help keep their population in check.

To distinguish between thrips and other similar-looking insects, you may use a hand lens or magnifying glass to examine their size, wing structure, and color. Compared to whiteflies or moths, thrips are smaller, and their wings are fringed with long hairs.

In conclusion, thrips may not pose a significant threat to humans through bites or other physical harm, but their potential to damage plants and crops can be problematic. By understanding their features and habits, you can identify and manage them more effectively.

Miscellaneous Information about Thrips

Thrips are tiny, slender insects typically found in soil, gardens, and on a variety of plants. They can enter your home through doors and windows, infesting your houseplants and outdoor plants as well. Thrips come in a range of colors, including brown, blue, white, black, and yellow. Some species, like the greenhouse and corn flies, are specific to certain habitats and host plants.

These insects can be harmful to your plants as they feed on plant nutrients and cause damage. At the same time, they can aid in pollination. Adult female thrips can lay their eggs in plant tissue adding to their population.

To manage thrips populations, consider implementing preventative measures. For example:

  • Maintaining proper moisture levels in your garden
  • Regularly inspecting your plants for signs of infestation
  • Using diatomaceous earth on the ground and potted plants

When dealing with thrips, it is essential to keep in mind that they are not harmful to pets. They are, however, often confused with spider mites – another plant pest. To differentiate between the two, remember that thrips are generally larger and more mobile.

Comparison between Thrips and Spider Mites:

FeatureThripsSpider Mites
SizeLarger (1 to 2 mm)Smaller (0.4 mm)
MobilityHighly mobileLess mobile
Plant damageFeed on plant nutrients, causing discolorationFeed on plant cells, causing stippling appearance

Knowing these facts about thrips can help you make better decisions when dealing with them in your home and garden. Remember to keep up with regular plant care and consider using natural methods to manage thrips populations, ensuring your plants stay healthy and thriving.

Velvet ants, despite their name, are not ants at all. They are actually wasps belonging to the family Mutillidae.

These colorful insects can be found worldwide and are known for their distinct appearance, with the females being wingless and covered in thick, hair-like setae.

The most common velvet ant species is Dasymutilla occidentalis, also known as the cow killer ant. But are these insects dangerous to humans or dogs?

Are Velvet Ants Dangerous
Velvet Ant

While velvet ants are equipped with a powerful sting, they are generally not aggressive creatures.

However, they will use their sting if they feel threatened or accidentally stepped on.

The sting is known to be quite painful and can cause allergic reactions in some individuals, but it is typically not life-threatening.

As for dogs, the potential danger is essentially the same as it is for humans.

If a curious canine were to disturb a velvet ant, the insect might deliver a painful sting in defense, but it is not likely to pose a serious threat to the dog’s overall health.

What Are Velvet Ants

Appearance

Velvet ants, often known as cow killers, are not actually ants but wasps.

They are wingless and covered with dense, velvety hair, usually displaying vibrant colors such as bright orange or red.

This unique appearance serves as a warning to potential predators.

Velvet Ant

Mutillidae Family

These insects belong to the family Mutillidae within the wasp family and can be found worldwide.

There are various species and several genera of velvet ants – the most common one in the United States is the eastern velvet ant (Dasymutilla occidentalis).

Males vs Females

Male and female velvet ants have noticeable differences:

  • Males have wings, while females are wingless
  • Females are slightly larger, reaching about 3/4 inch in length

Here is a comparison table:

 MalesFemales
WingsYesNo
SizeSmallerLarger

To sum up, velvet ants are wasps known for their bright colors and velvety hair.

They belong to the Mutillidae family and display sexual dimorphism, with females being wingless and larger than males.

Are Velvet Ants Dangerous to Humans and Dogs?

Sting and Venom

Velvet ants, also known as cow killer ants, are actually solitary wasps. They can potentially pose a risk to humans and dogs, particularly due to their sting and venom.

  • Sting: Despite their name, velvet ants do not have a painful bite like fire ants. Instead, females possess a painful sting comparable to that of a wasp. Males lack a stinger.

  • Venom: Velvet ants’ venom is potent enough to cause severe pain, and in some cases, can even lead to an allergic reaction.

Velvet Ant

Symptoms in Humans

Here are some common symptoms experienced by humans after a velvet ant sting:

  • Intense pain at the sting site
  • Redness and swelling
  • Itchiness and hives
  • Allergic reactions ranging from mild to severe, with the potential of anaphylactic shock in extreme cases

If stung by a velvet ant, it is important to seek medical attention if symptoms worsen.

Velvet Ant

Remember that despite their bright colors and apparent danger, velvet ants are solitary insects and not aggressive unless directly provoked.

They play a valuable role in controlling the population of other insects, as they feed on nectar from flowers and parasitize the larvae of ground-nesting bees and wasps.

So, while it’s essential to be cautious, keep in mind that velvet ants are also a beneficial part of our ecosystem.

Habitat and Behavior

Where Velvet Ants Live

Velvet ants, which are actually wasps, can be found in various habitats across the eastern United States, from Connecticut to Florida1.

They typically reside in open areas such as grassy meadows2.

  • Favorable habitats: grassy meadows, open areas
  • Geographic range: eastern United States (Connecticut to Florida)

Diet and Feeding Habits

Velvet ants feed on nectar from flowers as adults3. They are parasites that primarily target ground-nesting bees, wasps, and sometimes flies and beetles4.

  • Primary food source: nectar from flowers
  • Parasitic target: ground-nesting bees, wasps, flies, and beetles

Defense Mechanisms

Velvet ants are known for their aposematic coloration, which is a bright and vibrant warning coloration that signals potential predators to stay away5.

Velvet Ant

Additionally, they possess painful stings, and their venom is composed mainly of peptides6.

  • Aposematic coloration: bright, warning colors
  • Potent stings: venom contains peptides

Reproduction

Female velvet ants lay their eggs individually upon the immature stages of their host insects7. The eggs develop at the host’s expense, ultimately killing it8.

  • Reproduction strategy: parasitism
  • Host impact: eventual death

Common Misconceptions

Cow Killer Ants

One common misconception is that velvet ants, also known as “cow killer ants,” can kill cows. In reality, velvet ants are not ants but wasps belonging to the family Mutillidae.

The name “cow killer ant” likely arises from their painful sting, which can feel like a cow kick to unsuspecting victims – humans and animals alike. However, these wasps are not deadly to cows.

Some features of the velvet ant:

  • Bright colors
  • Thick, hair-like coating
  • Female: wingless and ant-like

Danger to Cows

Though the sting of a velvet ant can be extremely painful, it poses no substantial risk to cows.

People and animals might experience temporary pain or discomfort, but their stings are not powerful enough to kill a cow.

Velvet Ant

Cows might accidentally step on a velvet ant, but the repercussions are not lethal. It’s important to mitigate fear surrounding these creatures based on their nickname.

A comparison of velvet ant misconception vs reality:

MisconceptionReality
Can kill cowsDoes not have the power to kill cows
Is an antIs a type of wasp
Dangerous to humans and dogsOnly potentially causes pain and discomfort

Gender Differences

Understanding the gender differences in velvet ants can help clarify misconceptions about their danger or threat level.

Male velvet ants have wings, while female velvet ants are wingless and covered in dense hair, resembling ants.

Females are more easily noticed as they are larger and often scurry on the ground, while males are usually seen when feeding.

Despite these differences, neither males nor females pose a significant danger to cows, humans, or dogs.

Conclusion

Velvet ants, despite their name, are actually wasps. They’re known for their striking appearance and painful sting.

Female velvet ants lack wings and are covered in dense, colorful hairs.

While they can deliver a painful sting if provoked, they are not typically aggressive towards humans.

Their sting can be particularly intense, earning them the nickname “cow killer” due to the perceived potency of their venom.

However, they’re not usually considered dangerous unless you have an allergic reaction.

Red-Shouldered Bugs, are a common sight in gardens and landscapes. These insects have an elliptical shape and are dark gray in color, with bright red lines on their thorax. Their eyes are also a striking red color, making them easily identifiable.

Red-Shouldered Bugs are often confused with Boxelder bugs, another type of insect with similar red markings. To distinguish between the two species, it’s important to note that Boxelder bugs have three red stripes on their thorax, while Red-Shouldered Bugs have only two. Additionally, Boxelder bugs exhibit red outlines on their wings, which are not present in Red-Shouldered Bugs url.

These bugs are commonly found feeding on a variety of plants, including the Golden Rain Tree and other plants found in gardens. They generally do not cause significant damage to the plants they feed on, but may become a nuisance in large numbers. To manage their population in your garden, it’s essential to maintain a healthy habitat and implement natural pest control measures when necessary.

Identifying Red-Shouldered Bugs

Appearance and Size

Red-shouldered bugs, also known as Jadera haematoloma, belong to the Hemiptera order of insects. They have a dark gray or black body with distinctive red markings. These bugs are somewhat flattened and have an elongated, elliptical shape. The adults can measure between 3/8 to 5/8 inches in length (Kansas State University).

Red Markings and Wings

The red-shouldered bug’s main identifying feature is its bright red markings. The bug has:

  • Red eyes
  • Red antennae
  • Red lines on both sides of the thorax or ‘shoulder’
  • Leathery wings outlined in red (NC State Extension)

Host Trees and Habitat

Red-shouldered bugs can commonly be found on host trees such as the golden rain tree and the boxelder tree. These bugs may be confused with the similar-looking boxelder bug (Boisea trivittata), which also has red stripes on the thorax but also has red markings on the wings, unlike the red-shouldered bug (NC State Extension).

Comparison Table: Red-Shouldered Bug vs Boxelder Bug

 Red-Shouldered BugBoxelder Bug
Size3/8 to 5/8 inchesAbout 1/2 inch long
ColorDark gray to blackDark gray to black
Red markingsBoth sides of thoraxThree red stripes on thorax
 No red on wingsRed markings on the wings

By identifying the distinctive features and understanding their preferred habitats, one can easily differentiate red-shouldered bugs from other similar species.

Life Cycle and Behavior

Nymphs

Boxelder bugs, also known as red-shouldered bugs, have a life cycle that begins with eggs laid by females. The eggs, initially light yellow, soon darken to rusty red. After this, the nymph stage begins, during which they are small and wingless. Nymphs are about 1/2 inch long and resemble adults in color and shape, but their wings are not yet fully developed.

Adults

The final stage of the boxelder bug life cycle occurs when the nymphs transform into adult bugs. Adults have a dark gray to black color, with red stripes on their thorax and outlines on their wings. Their eyes are also red, giving them their distinct appearance.

Seasonal Changes

Boxelder bugs experience various seasonal changes in their behavior:

  • Spring: As temperatures rise, nymphs and adult bugs become more active, feeding on trees and plants.
  • Summer: During warmer months, they continue feeding and breeding, while nymphs grow and develop into adults.
  • Fall: As temperatures drop, boxelder bugs search for shelter in homes or other protected areas to overwinter.
  • Overwinter: Red-shouldered bugs remain in a state of dormancy until temperatures start to rise again in the spring.

Behavior:

  • Red-shouldered bugs are social insects, often found in groups.
  • Their primary food source is boxelder tree seeds or sap, but they may also feed on other plants.
  • They are considered a nuisance to homeowners due to their habit of entering homes in large numbers during the fall and winter months.

Comparison of Nymphs and Adults:

CharacteristicNymphsAdults
Size1/2 inch longAbout 1/2 inch long
ColorSimilar to adultsDark gray to black with red details
WingsNot fully developedFully developed wings with red outlines

In summary, boxelder bugs, or red-shouldered bugs, go through a life cycle that includes egg, nymph, and adult stages. Their behavior and appearance change throughout the seasons, with various impacts on their surroundings.

Feeding Habits

Diet and Preferred Plants

Boxelder bugs, also known as Red Shoulder Bugs, feed mainly on:

  • Leaves
  • Seeds
  • Host trees: boxelder, maple, goldenrain tree

They prefer to target plants like lilies and grass, but also consume seeds of boxelder and maple trees. To better understand their feeding habits, let’s compare boxelder bugs with goldenrain tree bugs:

FeatureBoxelder BugGoldenrain Tree Bug
Main dietSeeds of boxelder and maple treesSeeds of goldenrain trees
Other plantsLilies, grass, and other flowersLilies, grass, and other flowers

Impact on Trees and Gardens

Boxelder bugs and goldenrain tree bugs can cause damage to:

  • Leaves: Feeding on leaves can produce noticeable scarring along the edges and sides.
  • Flowers: Eating the flowers may reduce the plant’s ability to propagate and attract pollinators.

However, they are generally not considered severe pests as their impact on trees and gardens is usually minimal.

Prevention and Control

Natural Predators

Several natural predators can help control the population of black bugs with red bottoms, such as the red shoulder bug (Boisea trivittata). Beneficial insects, like the milkweed assassin bug (Zelus longipes) and native ladybugs, are excellent predators that feed on these nuisance pests. Gardeners can encourage their presence by:

  • Planting diverse and native plants
  • Providing shelter and water for insects

Pesticides

Pesticides can be an option to control black bugs with red bottoms. However, it’s essential to weigh the pros and cons of using them:

Pros

  • Effective in controlling bug populations
  • Can prevent infestations

Cons

  • May harm beneficial insects
  • Potential risk to pets and the environment

It’s important to follow the pesticide label instructions carefully and use them as a last resort.

Removal

Manual removal of these pests is also an option. Some common techniques include:

  • Vacuuming: Use a vacuum cleaner to remove bugs from walls and other surfaces. Remember to empty the vacuum bag or container to prevent the bugs from escaping.
  • Washing: A hose or pressurized water can be used to flush bugs off surfaces outdoors.

Remember to inspect your home regularly, seal cracks and crevices to prevent bug entry, and maintain a clean environment.

Lacewings are beneficial insects that play a crucial role in maintaining a healthy garden. They are available in two varieties, green and brown, with green lacewings being the most common. These delicate creatures help keep the population of pests, such as aphids, under control.

The lacewing life cycle has four stages: egg, larva, pupa, and adult. Overwintering occurs either as a pupa or adult, depending on the species. These insects are also often commercially available, making them easy to introduce into your garden.

Some interesting aspects of lacewings include:

  • Efficient predators in their larval stage
  • Adults generally emerge in the spring
  • Voracious appetite for aphids and other pests
  • Commonly found in yards, gardens, and forests

In summary, lacewings are beneficial insects that can be great additions to your garden ecosystem. Their strong predatory nature helps keep harmful pests in check, promoting a healthy and thriving environment for your plants.

Basic Biology of Lacewings

Green Lacewings

Green lacewings are a common type of lacewing with a transparent, delicate body and long, slender antennae. They are known for their role as beneficial insects in gardens due to their predaceous larval stage1. Some characteristics of green lacewings include:

  • Bright green color
  • Small heads
  • Wings with a delicate, net-like pattern
  • Presence of numerous species across genera2

An example of a green lacewing species is Chrysoperla carnea.

Brown Lacewings

While green lacewings are more prevalent, brown lacewings also play an essential role in biological control. Brown lacewings not only have predaceous larvae, but the adults also feed on aphids3. Some features of brown lacewings include:

  • Brownish color
  • Similar build to green lacewings but generally smaller
  • Less common than green lacewings

An example of a brown lacewing species is Micromus tasmaniae.

North American Species
