A recent field trip to Mount Remarkable National Park to collect bees and wasps was very successful when we found an unexpected population of a small parasitoid wasp from the genus Gasteruption. These wasps were flying low over the walking track inspecting holes and crevices. This wasp is very interested as it is very similar to a described species, Gasteruption angusticeps but has some morphological differences, could this mean it is an undescribed species? Or just variation? Ben Parslow, a PhD student in the LEGS lab is currently working in the systematics and host associations of this genus and will hopefully shed some light of this strange wasp group.
