Common Name: Honey bee Order: Hymenoptera Family: Apidae Photo Credit: John Obermeyer, Purdue University Pest Status: Honey bees are an extremely valuable insect, not only because they have been domesticated and produce honey and wax, but also because they are efficient plant pollinators. Appearance: Honey bees are about ½-inch long and have brown, hairy, yellow-striped abdomens. Life Cycle: Bees are social insects. Eggs are laid singly in cells in a wax honeycomb that is produced by the worker bees. Larvae are initially fed with jelly produced by the worker bees, but they eventually switch to honey and pollen. The larvae undergo several moltings before spinning a cocoon and pupating. Drones hatch from unfertilized eggs and females hatch from fertilized eggs. Where to Collect: Honey bees can be easily found around flowers and flowering trees. Beekeepers raise them in artificial hives by the thousands. Common Name: Horntail Order: Hymenoptera Family: Siricidae Pest Status: Horntail wasps are seldom found in sufficient numbers to be considered pests. Appearance: Adults resemble typical wasps, but each has a long abdomen with a spear-like plate on the last abdominal segment. They are relatively large and vary in length from ½ to ¾ inch. The females are marked with bright yellow and black and have long ovipositors. Males are mostly black. Life Cycle: Females deposit their eggs in “drilled” holes in the bark of trees. The larvae hatch and bore down into the tree, living there for up to two years before they pupate. When the adults emerge, they leave small holes in the timber. Where to Collect: Horntails can be found where there are many dead, dying, or recently felled trees.

Appearance: Horse flies are large (¾- to 1-inch long) and heavybodied with large heads. They can be brown, black, or gray and their eyes are sometimes crossed with red-gold bands. Life Cycle: Eggs are deposited in masses on vegetation near water. The eggs hatch within two weeks and the larvae drop down and burrow into moist soil found in marshes, stream banks, and bottoms of lakes and ponds. The larvae overwinter in these soils and eventually mature in the late spring. Pupation occurs in drier soil and usually lasts one week. The adults appear in early summer. Where to Collect: Horse flies are most active in hot weather. They also prefer wet environments. Photo Credit: John Obermeyer, Purdue University
Common Name: House fly Order: Diptera Family: Muscidae Pest Status: House flies are filth-breeding insects and can transmit diseases that adhere to their bodies. Appearance: Adults are ½-inch long and have gray thoraxes with four dark longitudinal lines on the back. The undersides of their abdomens are yellow, and their bodies are covered with hair. They have red, compound eyes. Life Cycle: Females lay their eggs singly in moist environments. The larvae develop over two weeks and the pupal stage lasts less than one week. Adults live for two months during warmer months. Where to Collect: During daylight hours, house flies will rest on floors, walls, and ceilings indoors. Outdoors, they will rest on plants, the ground, fence wires, and garbage cans. In all situations, they prefer edges or thin objects such as wires and strings. Photo Credit: John Obermeyer, Purdue University Common Name: Ichneumon wasp Order: Hymenoptera Family: Ichneumonidae Pest Status: Ichneumon wasps are parasites of wood-boring beetle grubs. Appearance: Adults can range in length from 1 ⁄8 to 5 inches. Most are slender. The most distinctive feature is that the female of many species has an extremely long ovipositor for laying eggs deep into the trunk of a tree. They have brown bodies with black and yellow markings and transparent wings. Life Cycle: Most species overwinter in cocoons as mature larvae. The larvae hatch from eggs inserted into tunnels in the bark of trees. The larvae develop through several instar stages before pupating. Adults emerge in the spring. Where to Collect: Ichneumonids are found around dead, deciduous trees. Photo Credit: John Obermeyer, Purdue University Common Name: Indian meal moth Order: Lepidoptera Family: Pyralidae Pest Status: Indian meal moths are common pests of stored foods in homes as well as in food handling establishments. Appearance: Adults are small ( 3 ⁄8-inch long) with a wingspan of about 5 ⁄8 inch. The overall body color is generally brown-gray, but the tip half of the wing is rust or bronze colored. Life Cycle: Female moths lay their eggs singly or in clusters on suitable larval food. The larvae hatch from the eggs and produce silken tunnels for protection while feeding. Larval development time varies with temperature and type of food material. Before pupating, the larvae leave the food source. Where to Collect: Moths are often found flying in kitchens and other rooms of the house. Sometimes, the appearance of moths is an indication of a breeding population of larvae in some type of stored food. Photo Credit: John Obermeyer, Purdue University
