Never assume anything about the insect and spider world.
Never. You'll be proven wrong most of the time. This fly here is endangered and I wish I could do something to save it. But I can't atm as I don't have the credentials for such a thing. Hopefully someday I will.
Wikipedia provides some rather substantial info on Rhaphiomidas terminatus abdominalis:
The Delhi Sands flower-loving fly (Rhaphiomidas terminatus abdominalis) is a mydid fly in the genus Rhaphiomidas, and the only fly presently on the Endangered Species List.
This subspecies is restricted to the Delhi Sands formation, an area of ancient inland dunes of which only a few hundred acres out of more than 40 square miles (100 km2) remain.
The rest largely now forming much or all of the foundation on which the towns of Colton, Fontana, and Ontario California are built. The adults are only active for a few weeks each year, feeding on flowers, in August and September.
This fly was emergency-listed by the United States Fish and Wildlife Service on September 23, 1993, and it has been an extremely contentious listing ever since. Political officials and news services from the region have repeatedly decried this fly as a disease-carrying pest, despite documentation that it is not.
There have been repeated attempts by local officials to have the species de-listed. Residential and commercial development, agricultural conversion, sand mining, invasion by exotic species, dumping of cow manure and trash, and off-road vehicle use have resulted in significant loss and modification of the species' habitat.
Estimates are that over 97% of the original habitat is already gone, and only a portion of what remains is suitable habitat for these flies.
I swear when I hear stuff like this I feel more and more ashamed of what we're doing. People need to get their act together and do something already.
Poor fly....Hang in there. The human species is despicable.
