tangle-veined fly
Neorhynchocephalus sackenii is a species of tangle-veined fly in the family Nemestrinidae. It is known primarily as a parasitoid of grasshoppers, with documented associations to at least two rangeland grasshopper species in western North America. The species constructs specialized respiratory pores in its host and has been observed to cause significant mortality in grasshopper populations, with parasitism rates varying from 0 to 40 percent in field studies.
