Adult iris borers are stout, medium sized moths with a wingspan of 3.8–5 cm (1.5–2 inches). The head and forewings are covered with purplish brown scales and the hind wings are yellowish. The forewings have thin dark zigzag lines, a more conspicuous dark kidney-shaped spot, and variable sooty shading around the margins. The bottom edge of the forewings is noticeably scalloped. Eggs are highly sculptured and are found primarily in the folds of dried out, brown, dead leaves of iris plants. Initially a creamy color with a greenish tinge, the eggs turn lavender with age. Full grown caterpillars are cylindrical, smooth, and pinkish-white. They measure up to 4.4 cm (1.7 inches) long. Pupae are dark brown to nearly black and very shiny.

|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.

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.

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.

|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).

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.

|How to Identify a Bed Bug Infestation||
You cannot just “get” bed bugs. They have to be brought into your home. So what is your first clue that you have brought bed bugs home (say after a trip, or after purchasing a piece of used furniture that you bought at a garage sale)? Most people become suspicious of a bed bug infestation when they find unexplained bites on their bodies.

|Gypsy Moth in Virginia: An Update||
Most Virginians are aware that the gypsy moth is a serious pest of hardwoods in our state. Although this insect has maintained a low profile the past few years, there was a general resurgence in moth populations in 2000. This population increase serves as a reminder that, in areas where gypsy moth has become established, this pest is still present in the environment even when populations are too low to be noticed.
Gypsy moth is a native of Europe, Asia, and northern Africa. It was accidentally released in the U.S. over 130 years ago by a Frenchman who wanted to cross it with native silk moths. From its original introduction near Boston, Massachusetts, this pest has spread into the mid-Atlantic and Midwestern states (Fig. 1).

|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.

The Japanese weevil has a long list of hosts, but is especially found on cherry laurel, broad-leaved evergreens, pyracantha, privet, barberry, euonymus, and many others. This weevil has also damaged vegetable and field crops in Virginia.

|Magnolia Soft Scale||
Heavy magnolia soft scale infestations cause stunting of twigs and undersize leaves, visibly weakening the trees. Small trees may be killed. Large trees lose branches and tree shape may become irregular.

|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.

|Giant Resin Bee||
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.
