Identify my pest
Tired of unwanted bugs but no idea what they are? Below you will find the most common pests and the Insect Heroes that will help you solve the pest.
Recognizing mourning flies
Fungus gnats, also called fungus flies, can be recognized as small black flies that fly around the potting soil of houseplants. Many people confuse them with fruit flies.
Adult mourning flies
Mourning flies are not actually flies but non-stinging mosquitoes. They have long antennae, a dark color and fly quite slowly. The adult mosquitoes are up to 3 mm in size and easy to see with the naked eye.
Mourning flies eggs
The adult mourning flies lay eggs in the potting soil where larvae hatch. The damage can only be seen underground.
Mourning flies larvae
The fungus fly larvae are transparent in color and resemble small worms. The larvae cannot move far and therefore damage is always local.
Mourning flies damage
The larvae of fungus flies live in the soil and prefer a moist and nutrient-rich soil. They mainly eat rotting plant material and the fungi that grow on it. The larvae also gnaw on the roots of young plants.
Be careful not to water the plants too much, especially in winter. This way you create a perfect environment for the mourning fly larvae.
Recognizing aphids
Aphids are small, bulbous insects of a few millimeters in size. They can reproduce very quickly, which means you can quickly have a large pest in the plants.
Aphid appearance
Aphids can have all kinds of colors: green, black, brown or red. They like to sit in groups on the underside of the leaves or on the stem.
Aphid white
Aphids molt several times as they grow. These white skins are an indication that you have aphids in your plants.
Aphids and ants
You can recognize aphids indirectly by the presence of ants. Aphids secrete a sweet, sticky substance that attracts the ants. This substance is called honeydew. Fungi can also grow on this, which is often called sooty mold.
Aphid wings
If there are a lot of aphids together, they form wings and fly to another part of the garden. This way the plague spreads quickly.
Recognizing thrips
Thrips are so small that you have to look carefully to find them. Thrips has an elongated body with small ragged wings. They are about 1 to 2 mm in size and often yellow, brown or black in color.
Thrips larvae
The larvae of thrips are light yellow to transparent in color. They are therefore more difficult to discover than adult thrips. In this photo you see the larva and the adult tobacco thrips.
Thrips damage
Thrips cause damage by sucking plant cells dry. This causes silver-gray spots on the leaves: dead plant cells. You also see black dots in the gray spots. These are the droppings of thrips.
Thrips eggs
Many thrips species lay their eggs in the leaf tissue. The eggs are difficult to detect and combat.
Recognizing spider mites
Spider mites drink plant sap from the underside of leaves. A plant cell is punctured and sucked dry, and the dead plant cell turns yellow. This causes yellow spots on the leaves of your plants.
Spins webs
The mites also make silk, small webs, between the leaves. The spider mites use the webs to move quickly. Together with the yellow spots, they make the plant look less attractive.
Spider appearance
Spider mites are small round creatures that look a bit like spiders or ticks. They are up to 0.5 mm in size and are best seen with a magnifying glass.
Spider mites colors
Spider mites can be different colors, from brown to red to green. The color depends on the type of food that spider mites eat. The spider mite can be recognized by two dark spots on its body.
Recognizing mealybugs
You can recognize mealybugs at first glance by the fluffy white spots near the veins of the leaves. This is a substance that the mealybugs secrete.
Adult mealybug
If you remove the waxy threads you will see small white to light pink creatures appear. They are 4-5 mm in size.
Mealybug honeydew
The leaves may feel sticky due to honeydew. Honeydew is a sugary substance excreted by mealybugs. Sooty molds can grow on the sugars.
Mealybug damage
Most damage is caused by mealybugs sucking plant sap, which weakens the plant and makes it grow less quickly.
Yellow leaves due to mealybug
Leaves may turn yellow and fall off. Flowers or fruits can also eventually fall off.
Recognizing vine weevil
The vine weevil, also known as the vine weevil, is easy to recognize by the damage it causes to the plant. The round bites from the side of the leaf indicate its presence.
Adult vine weevil
The vine beetle is a small, dark beetle measuring 7 to 10 mm. He has light spots on his elytra. and cannot fly.
What plants does the vine weevil eat?
During the day the weevil hides, but at night it happily nibbles on leaves of rhododendron, cyclamen, azalea and strawberry.
Catching vine weevil
You can catch the adult beetle by placing a plank of wood in the garden with grooves on the underside. The Taxus beetle crawls into the groove and can be removed during the day.
Recognizing whiteflies
Whitefly is a small insect about 3 mm in size with white, powdery wings. As soon as you shake the plant, the bugs fly up.
Whitefly larvae
The larvae of whiteflies are transparent in color and are located on the underside of the leaf. Here they suck on the plant sap of the plant.
Whitefly damage
Adult whiteflies also suck on the leaves. This weakens the plant. They secrete the excess sugars that the whiteflies ingest. This sweet, sticky substance is called honeydew. Sooty molds like to grow on honeydew, which is not a nice sight on the plant.
Whitefly species
In the Netherlands there are 3 species of whitefly: tobacco whitefly, greenhouse whitefly and cabbage whitefly. In the photo you can see greenhouse whitefly. The greenhouse whitefly has its wings slightly crossed, in the shape of a triangle.
Recognizing grubs
In the lawn you can recognize grubs by yellow spots in the grass. The beetle larvae gnaw on the roots of the grass, causing the grass to die.
Grubs appearance
Grubs are larvae of different species of beetles. The larvae can be recognized by their milky white, worm-shaped body that curls up like the letter 'C'.
Grubs and leatherjackets
Many people confuse grubs with leatherjackets. Grubs are easy to distinguish from leatherjackets by looking at the legs and head. Grubs have a rusty brown head with 3 pairs of legs, which are missing in leatherjackets.
Recognizing leatherjackets
Leatherjackets are the larvae of crane flies. They also nibble on the roots of grass, causing bare spots in the lawn.
Leatherjackets and birds
If you see many birds in the lawn, this may also indicate leatherjackets. The birds peck, dig and toss in the grass to find and eat the leatherjackets. This can cause additional damage to the lawn and lead to bare spots.
Leatherette appearance
Leatherjackets look like gray-brown, fat worms of 1 to 5 cm in size. No clear head can be distinguished. Leatherjackets have no legs, unlike grubs and wireworms.
Discovering Emelten
Leatherjackets are located in the top layer of the lawn. You can find the leatherjackets by removing some dead gas and digging with a shovel.
Recognizing box tree moth
Box tree moths do not cause any damage, only the box tree caterpillars. The caterpillars eat the leaves of boxwood bushes, causing the boxwood bush to become completely bare. The damage often starts at the bottom of the shrub. Spinning also appears between the leaves.
Boxwood caterpillar appearance
To find boxwood caterpillars, you have to look carefully between the leaves of the boxwood shrubs. The young caterpillar is green in color and therefore easily disappears between the green leaves. The animal is easily recognizable due to its black head. When the caterpillar is a bit older, the black longitudinal stripes on the body are more visible.
Box tree moth appearance
The adult boxwood moth has white wings with a dark brown edge. The moth is active at night and is therefore less visible during the day.
