It is an attractive insect with metallic green thorax and bronzy red or green abdomen. Legs are a dull milky yellow colour.

    Life History

    The ovipositor is so long that when the female Torymus bedeguaris lands on the gall, she can push it through the gall to deposit her eggs inside. When these hatch her larvae will parisitise the larvae of the cynipid wasps.
