Most megastigmids range in colour from yellow to brown. However, some may feature patches of metallic green. Megastigmids can generally be recognized among other Chalcidoidea by the presence of an enlarged stigma on the wing, often with an
infuscate area around the stigma. They can be confused for Torymidae, within which they were formerly nested, due to their similar range in body sizes, and the long excised
ovipositor in females. However, the presence of this enlarged stigma and the presence of 6
flagellomeres between the
pedicel and
clava (instead of 8 in Torymidae) separate the megastigmids. ==Ecology==
