The representative species of this group, such as Gambrus sp. (A) and Itoplectis conquisitor (Say) (B), are larger than other parasitic wasps. They have a slender body; very distinct head, thorax and abdomen; two pairs of membranous wings and long, segmented antennae. The female’s needle-like ovipositor (at the tip of the abdomen) is as long as or longer than its body. They are harmless to humans. Note: These wasps are extremely sensitive to most broad-spectrum insecticides.
