Title Summary Date ID Author(s)
Aphids, or plant lice, are small, soft-bodied insects. There are hundreds of different species of aphids, some of which attack only one host plant while others attack numerous hosts. Most aphids are about 1/10 inch long (2.54 mm), and though green and black are the most common colors, they may be gray, brown, pink, red, yellow, or lavender. A characteristic common to all is the presence of two tubes, called cornicles, on the back ends of their bodies. The cornicles secrete defensive substances. In some species they are quite long, while in others they are very short and difficult to see. Aphids feed in clusters and generally prefer new, succulent shoots or young leaves. Some species, known as wooly aphids, are covered with white, waxy filaments, which they produce from special glands. Order: Homoptera, Family: Aphididae

Aphids in Virginia Small Grains: Life Cycles, Damage and Control

Four species of aphids attack small grains in Virginia -- greenbug, corn leaf aphid, bird cherry-oat aphid, and English grain aphid. In general, these aphids are small pear-shaped insects (1/16 to 1/8 inch long) that are green to nearly black, or sometimes pinkish in color. Immature aphids look just like adults except smaller. Both winged and wing-less forms can occur in the same colony. All grain aphids have a pair of conicles, tailpipe-like projections, on the top side of the tail end. Aphids feed singly or in colonies on upper and lower leaf surfaces and stems. They feed near plant bases when plants are young or during cold weather, and on upper-canopy leaves, stems, and even grain heads later in the season.

Asparagus Beetles

Two species of asparagus beetles are found in Virginia, the asparagus beetle, Crioceris asparagi (L.), and the spotted asparagus beetle Crioceris duodecimpunctata (L.). Adults of the asparagus beetle are 1/4 inch (6.25 mm) long, metallic blue to black, and have wing covers with three or four white spots and reddish margins. The thorax is red and usually marked with two black spots. The spotted asparagus beetle is about 1/3 inch (8.3 mm) long and orange with 12 spots on its wing covers. Larvae of both are olive green to dark gray with a black heads and legs. Larvae measure about 6/100 inch (1.5 mm) at hatching, and as they develop they become plump and attain a length of about 1/3 inch (8 mm). Both have eggs that are approximately 4/100 inch (1 mm) long, oblong, shiny, black,\ and are attached by one end to asparagus spears.

Asparagus Beetles on Asparagus

The asparagus beetle is a sporadic pest that can be aggravating for asparagus growers throughout Virginia. The shoot damage not only reduces the quality of the spears but this beetle is also unique in the pest world, as it is an insect that is controlled because the eggs laid on the shoots is objectionable to consumers. With a little background on this pest most growers are able develop an effective pest management program.

Bark Beetles
Species identification is difficult because the adult beetles of the various species are very similar, cylindrical and hard-shelled. Over 600 species in the sub-family. Adult beetles are between 1/8 and 1/3 inch long. Nearly all bark beetles are black or brown. Bark beetles are in the Order: Coleoptera, Family: Curculionidae, Sub Family: Scolytinae.

Beet Webworm Apr 25, 2011 3104-1542
Black Vine Weevil

Plants Attacked: The adults feed on a wide variety of evergreen, deciduous, and herbaceous plants. The larval form is destructive on yew (taxus), hemlock, rhododendron, and several other broad-leaved evergreens. Adults and larvae will sometimes feed on strawberry and impatiens.

Description of Damage: Two kinds of damage are conspicuous: Adults chew marginal notches in leaves, causing damage that quite often is confused with a disease or chemical injury. The adults feed from the outer margin of the leaf inward, creating characteristic notches, and these notches can be used as an early indicator of potential larvae in the soil. Adults cut notches on the margins only; they never create holes on the center of the leaf. On yew, needles nearer to the main trunk, down inside of the shrub, show notching and feeding scars. Broadleaved evergreens exhibit notching similar to that caused by the two-banded Japanese weevil and Fullers rose beetle. Larvae, the most destructive form of this weevil, feed on roots. When large numbers of larvae are feeding on the roots, the plants will wilt, turn brown, and die.

Blister Beetles

Blister beetles have seven instars and overwinter as mature larvae in the soil. After pupation in the spring, adults begin to emerge in early summer and by midsummer reach their peak population. During summer months blister beetles feed on plant foliage or flowers and mate. Eggs are laid in the soil in groups of 50 to 300 eggs. Ten to 21 days’ later larvae emerge from these eggs and search for their preferred food--grasshopper eggs. As larvae molt and grow their activity decreases. When they reach the fifth instar they move into the soil, molt again, and remain overwinter in the soil as sixth instars.

Blow Flies

Adult blow flies are generally

medium to large, robust flies. They vary in

length, with the largest species measuring about 16 mm (0.6 inches) long. They can be green, blue, or black with metallic reflections. Some species have conspicuous bristles. All adults have large, noticeable reddish-brown eyes. The wings are transparent and held flat over the back. Adults often cluster in the sun on warm sides of buildings, outcroppings, fences, and other prominent structures. They are sometimes found visiting flowers and feeding on nectar.

Brown Marmorated Stink Bug

Homoptera: Penatomidae: Halyomorpha halys

Distribution and Hosts

The brown marmorated stink bug, (BMSB), is an invasive insect not native to North America. It was accidentally introduced near Allentown, PA in 1996 and has spread since that time. It was found in Virginia in 2004 and by 2010, it was found throughout most of the Commonwealth. The BMSB feeds on a wide range of tree fruits and seedpods as well as many vegetables including tomatoes, peppers, beans, cucurbits, and sweet corn. High densities of this pest species have also been seen in soybeans and corn. However, so far in Virginia, the most severely damaged crops have been tree fruit (apples and peaches). For homeowners, it is mainly a nuisance pest, as it invades houses in the winter looking for a place to over-winter. For businesses such as hotels and restaurants and other commercial settings with public interface, the presence of high numbers of these bugs in the fall can have economic consequences.

Brown Recluse Spider

Brown recluse spiders belong to a group of spiders commonly known as violin spiders or fiddlebacks. Their name refers to a characteristic fiddle-shaped pattern on their head region directly behind their eyes (never on the abdomen). Brown recluse spiders range in color from tan to dark brown, but often they are a golden brown. The coloration is generally uniform (head and abdomen are about the same color) with no stripes or bands on the legs. The fiddle marking is usually dark brown or black, with the neck of the fiddle pointing towards the abdomen. Hairs on the body are fine, not coarse, and the fiddle pattern is often shiny. The body measures 8–10 mm long (about 0.4 inch).

Carpet Beetles

 The four most important and most common species are the black carpet beetle (Attagenus mezatoma) shown here, the varied carpet beetle (Anthrenus verbasci) , the common carpet beetle (Anthrenus scrophulariae) , and the furniture beetle (Anthrenus flavipes) . The adults feed primarily on pollen and nectar and can be found on outdoor plants during the summer. The adult stages of carpet beetles are small, oval insects, usually less than 1/4 inch long. Carpet beetle larvae are usually about the size of the adult beetle, 1/4 inch or less in length but they have dense tufts of long setae (bristles) on their bodies. Black carpet beetle larvae have a long tuft of hair at the end of their bodies. Adult carpet beetles are commonly found indoors at windows. Carpet beetle larvae often wander about the infested location-- from room to room in a house. This behavior results in spreading the infestation throughout the house. Coleoptera: Dermestidae.

Catalpa Sphinx Caterpillar

Catalpa sphinx caterpillars, also known as “Catalpa worms”, are major defoliators of catalpa, their only host. With their chewing mouthparts, they strip away large portions of the leaves. In heavy infestations they can completely defoliate the entire tree. Apparently trees on high ground with poor soil are rarely, if ever, attacked. In some years, depending on the region, many trees will have all their leaves stripped away by the end of the summer. This may be followed by years with no defoliation observed at all. The fluctuation between outbreak and no defoliation is largely due to the activity of parasites.

Clothes Moths

The Webbing Cloths Moth, Tineola bisselliella, is commonly found under wool carpets and other situations where wool or hides rest on a floor or a surface. The larva is a caterpillar that can be up to пњљ inch long and has a shiny hairless pale appearance. Often the color of the dye on the wool on which they feed is visible through their bodies. In addition to leaving webbing where they feed, they also make web tunnels and leave droppings. The adult is a very small yellow moth with long hairs on the head.

Cluster Fly

Adult cluster flies are medium-sized, robust, somewhat bristly flies about 7 mm (0.3 inches) long. They are brownish-gray with numerous short yellow hairs on the thorax, a checkered pattern on the abdomen, and large, reddish-brown eyes. Adults are typically slow fliers. In the fall they begin to cluster in the sun on the warm sides of buildings, outcroppings, fences, and other prominent structures as they seek protected places to overwinter. They may enter houses and other buildings in large numbers. Homes built on the top of a hill or otherwise stand out in the landscape may attract many cluster flies. While cluster flies are a nuisance in the home, they do not bite, are not associated with the transmission of disease, and do not reproduce inside buildings. Cluster fly larvae (maggots) are parasites of earthworms and develop in the soil. They are not known to reduce earthworm populations to the extent that they disrupt soil ecology.

Corn Earworm Biology and Management in Soybeans

Corn earworm, Helicoverpa zea, is the most common and destructive insect pest of soybeans grown in Virginia. Although infestation severity varies, about one-third of our acreage is treated annually. This costs farmers 1.5 to 2 million dollars annually, and requires the application of many pounds of insecticide to crop lands. We may never eliminate this pest from Virginia soybeans, but knowledge of the biology and use of best management practices can help limit insecticide controls to those fields that meet economic threshold criteria. This publication provides current information on corn earworm biology, prediction of outbreaks, pest advisories, scouting procedures, and recently revised economic thresholds.

Dogwood Borer
Larvae feed in the inner bark of live, healthy dogwood trees. The damaged area of the trunk or branch swells and eventually the bark will fall off. Leaves turning red prematurely in mid-summer on a lone branch are an early sign of dogwood borers. Infested branches and limbs will die. Dogwood borers often will not kill the tree in the first year, but reinfestation in successive years will. Plants attacked include: Dogwood, pecan, elm, hickory, and willow.
Nov 18, 2014 2808-1010 (ENTO-90NP)
Dogwood Twig Borer

The larvae tunnel in live twigs and feed down the center of the branch, making a long series of closely placed round holes for the exudation of frass. Periodically, the larvae cut off portions of the twig from within and continue to feed inside the twig on the green wood working their way down.

Earwigs in Virginia

Earwigs can be up to 1 and 1/4 inches (25.4 - 31.8mm). Most are Red-brown to black in color. Adult earwigs are flattened insects, up to 1 and 1/4 inches in length, and light red-brown to black. Some species are wingless but others have a pair of leathery forewings covering a few segments of the  abdomen and the membranous hind wings, which have the tips protruding. The forceps-like appendages at the end of the abdomen are strongly curved in the male. The female's appendages are smaller and less curved. The forceps are used primarily for defense and during courtship and cannot harm people. Earwigs are primarily scavengers on dead insects and rotted plant materials. Some species are predators. Only a few of the winged species are good fliers. They are often transported great distances in plant materials and occasionally in other freight. The most common earwig in Virginia is the European earwig, Forficula auricularia. Dermaptera: Forficulidae.

Emerald Ash Borer

The first indication of damage by the emerald ash borer is cracks in the branch’s high in the tree followed by canopy dieback. Tunneling by the larvae cause girdling and death of branches and the trunk. Early feeding damage by emerald ash borer will be difficult to detect because trees show few symptoms. Woodpeckers feeding on EAB larvae leave holes in the bark that can be seen by looking up into the tree. As the infestation progresses the trees starts to thin out and branches in the top sections of the tree start to die. Many trees will have a large number of new shoots on the trunk called epicormic branching. Often these branches occur at the junction of thelive and dead sections of the trees. Epicormic branching may also occur at the base of the tree after the tree has died. EAB can live in twigs as small as 1 inch in diameter but can also breed in trunks of fully mature trees. It usually takes 2-5 years for damage to be noticed and the EAB damage kills the tree shortly thereafter.

Euonymus Scale
Eggs are laid early in the spring and hatch in late May or early June. The crawlers settle quickly and produce a second brood by mid-July. A third brood is produced in October. There is continuous overlapping of broods, so that all stages may be found during favorable conditions. Two to three-plus generations per year may occur in Virginia. The overwintering stage is the adult female.

European Corn Borer

Description of Damage

European corn borer (ECB) is a major pest of corn grown for grain in Virginia. This pest is found throughout the commonwealth, but its population density fluctuates from year to year in a given locality. Typical damage to corn plants caused by this insect are reduced plant vigor leading to subsequent ear drop and stalk lodging.


When fully grown, ECB larvae are 3/4 to 1 inch in length and creamy-white to pink in color. The larval head capsule is dark brown and, on top of each abdominal ring or segment, there are several small dark brown or black spots. (Figure 1)

Galls and Rust made by Mites

Galls are abnormal growths of plant tissue induced by insects and other organisms. Gall-making parasites release growth-regulating chemicals as they feed, causing adjacent plant tissues to form a gall. The parasite then develops within the relative security of the gall. Galls come in an endless variety of forms. Many are strikingly colored or curiously shaped. Each gall-making species causes a gall structurally different from all others. By noting the type of host plant and the structure of the gall, one can identify the gall-making mite without actually seeing it.

Size: about 0.75 inch (1.9 cm) Color: Black and yellow-brown Giant resin bees are large with a cylindrical body and large jaws. They have a dark head and abdomen with yellow-brown hair on the face, thorax, and the first segment of the abdomen behind the "waist." The wings are a transparent brown color that darkens toward the tips. Male giant resin bees have a truncated, squared abdomen while the females have a more tapered, pointed abdomen. Giant resin bees can be distinguished from bumblebees and carpenter bees by their cylindrical bodies and the appearance of their abdomens. Giant resin bees do not have hairy abdomens like bumblebees, nor are their abdomens shiny like carpenter bees. Hymenoptera: Megachilidae Megachile sculpturalis Smith.

House fly

Adult house flies are medium-sized flies about 6 mm (0.25 inch) long. They are grayish-black in color, with 4 dark bands running the length of the thorax and conspicuous bristles on the body. The abdomen is usually yellowish or gray, with a dark midline. The large eyes are reddish-brown and there are silvery patches between the eyes on the face. There are two pairs of wings, but the hind wings are small and modified for balance during flight. Adults often cluster in the sun on the warm sides of buildings, outcroppings, fences, and other prominent structures. House fly larvae (maggots) are found in dung, garbage, and rotting organic materials. Homeowners may find house fly maggots in garbage cans that have been left uncovered and not emptied regularly, or in improperly stored food.

Lace Bugs - Hemiptera: Tingidae

Lace bug damage is first noticed as yellow spots on the upper leaf surfaces of affected plants. Lace bugs actually feed on the undersides of leaves with their piercing-sucking mouthparts, but because they kill surrounding cells as they feed, they cause the yellow spots to appear on upper sides of the leaves. The first yellow spots that appear are very similar to mite damage, but the spots made by lace bugs are much larger. When feeding damage becomes severe, the leaves take on a gray, blotched appearance or can turn completely brown. As lace bugs feed they produce brown varnish like droppings that spot the underside of the leaves. These droppings further distinguish lace bug damage from mite damage. When large numbers of lace bugs are present cast skins can be found attached to the leaves. Hemiptera: Tingidae

Lice Found on Humans

Human head and body lice are wingless, flattened insects with mouthparts for sucking blood. The head is somewhat narrower than the rest of the elongated body. Adults are small, about the size of a sesame seed (2.5–3.5 mm; 0.1 inch). Head and body lice are gray to tan in color. If they have fed recently, the blood meal will be visible through the body and make them appear darker. Bloodsucking lice have a large claw at the end of each leg that fits snugly around a hair shaft, allowing them to cling securely to their host or the fibers of their clothing. Lice cannot fly or jump; they can only crawl.

Mosquitos and their Control

Most common mosquitoes are brown to black with tan or white lines or markings. All pest mosquitoes have a long beak or proboscis that is used for feeding. In addition mosquitoes have three pairs of long, slender legs and are 1/4 to 1/2 inch long (6.4-12.7 mm). Immature mosquitoes are worm-like and called wrigglers because of the way they move in water. They are also 1/4 to 1/2 inch long (6.4-12.7 mm).

Multicolored Asian Lady Beetle in Virginia

Multicolored Asian Lady beetles enter the house through small openings around windows, doors, and utility access points. In addition, they can enter the house by cracks in the siding and trim and through attic vents. Sealing those entry sites is the best method to keep them from becoming indoor pests later. Conduct a thorough energy audit of your house, as places where cold air can enter the house are places where this lady beetle can gain access. Fill all cracks and leaks with a fine quality silicone or silicone-latex caulk.  Once inside, insecticides are not recommended except for severe cases. Sweep up with a broom and dustpan all beetles that collect in windowsills and on walls. Beetles can also be picked up with a vacuum cleaner but bags will need to be discarded so that beetles do not escape.

Obscure Scale

Heavily infested trees will have large numbers of scales on twigs and branches.
Scales may also be found on exposed roots and on the trunk of young trees. Scale insects feed on plant sap with their long thread-like mouthparts (stylets), which are several times longer than the insect itself.

Periodical Cicada

In Virginia both the 17-and 13-year cicadas damage many ornamental and hardwood trees. Oaks are commonly attacked but the most seriously damaged are newly planted fruit and ornamental trees such as apple, dogwood, peach, hickory, cherry, and pear. Pines and other conifers are not commonly attacked.

Rose Chafer

Rose chafer larvae overwinter in
the soil. As temperatures rise in the spring
larvae move up towards the soil surface and
pupate. In a few weeks adult beetles emerge
and begin feeding for a period of about four to
six weeks. Females deposit groups of 6-40
eggs about six inches below the soil surface in
sandy or grassy areas. Larvae hatch in one to
three weeks, depending on temperature, and
begin to feed on roots. One generation occurs
annually in Virginia.

Spotted Lanternfly

The spotted lanternfly (SLF) originates from China where its presence has been documented in detail dating as far back as the 12th century. In modern times, it was first recorded from a sample collected in Nankin, China. SLF is native to China, India, Japan, Korea, and Vietnam. In September 2014, the first detection of spotted lanternfly in the US was confirmed in eastern Pennsylvania. In 2015, the range expanded from two to four Pennsylvania counties; the geographical range is likely to expand further. SLF is likely to have arrived from China up to two years earlier on shipping materials, pointing to its ability to overwinter successfully. It is highly invasive and can spread rapidly when introduced to new areas. This is attributed to its wide host range (more than 70 host plant species) and a lack of natural native enemies.

Stink Bugs

Adults and nymphs suck sap, feeding primarily on buds and seedpods. This feeding results in weakened plants and malformed buds and fruit. On okra and bean pods, the damage appears as pimples or wart-like growths. On tomatoes and peppers, white marks, often resembling halos, appear on the fruit. On pecans and beans, the damage shows up as brown spots on the nutmeat or seed. On some tree fruit, stink bugs can cause a deforming condition called cat facing on the fruit.

Wheel Bug

The wheel bug is one of the largest members of the family of insects known as
assassin bugs. Most members of the family are predacious on other insects. The adult is brownishblack
and about an inch long. It has a distinctive semi-circular crest behind the head, which
resembles half a cogwheel (thus the name wheel bug). The long, slender antennae, beak, and ends
of the legs are reddish brown. The head is very narrow and slightly constricted behind the eyes
forming a slender "neck." Bending down and back from the front of the head is a rigid, 3- segmented beak. The nymphs are small and
lack the cogwheel crest. Their abdomens are
bright red and curl upward when they are

Yellow Poplar Weevil

Rice-shaped holes about 1/16 inches result from adult feeding. Larval feeding forms mines, usually two per leaf. If they are both on the same side of midrib, one is extensive, and the other dwarfed. If the insect lays eggs on opposite sides of the midrib, both mines develop normally.
