Braconidae and Ichneumonidae

Jeff Hahn, University of Minnesota


Jeff Hahn, University of Minnesota

Size: Variable; Up to 4 1/2 inches including ovipositor.

Description: Generally slender, cylindrical bodies; long antennae, often as long or longer than its body; ovipositor generally as long as body; color variable.

Where/When: Occasionally found indoors, primarily in the winter. They parasitize wood borers that may be found in wood, especially firewood.

Significance: Even though they have a long ovipositor, they do not harm people. They do not infest wood or otherwise damage property and are only a nuisance.
