Phasia robertsonii
ball-nosed planthopper
A tachinid fly species in the genus Phasia, originally described from North America. The species has been reclassified from the genus Fitchiella, where it was previously placed as a planthopper. As a member of the Tachinidae family, it is a parasitoid fly. A 1995 study by Day documented biological observations identifying it as a native parasite of adult plant bugs (Miridae) feeding on alfalfa and grasses.
