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 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).

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.

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.

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.

Iris Borer

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.

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).
