About Tromatobia ovivora
Tromatobia ovivora has larvae that consume spider eggs inside egg sacs.
Ecology and introduction history
Tromatobia ovivora has larvae that consume spider eggs inside egg sacs. Hawaiian literature also recorded it under Tromatobia rufopectus. This egg-sac association differs from a wasp that captures adult spiders to provision a nest. Kauaʻi is within its documented island distribution. The record does not identify all spider species attacked locally or quantify the effect on native spiders.
