what is it?
Trichilogaster acaciaelongifoliae is a species of Australian chalcid wasps that parasitises, among others, Acacia longifolia (long-leaved wattle, or Sydney golden wattle), which has become an invasive pest in several countries. T. acaciaelongifoliae has been introduced into South Africa as a generally successful biological control agent of A. longifolia .
