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. |
