Stiletto Fly captured by a crab spider on Sandpaper Plant - Ammonaios confusus - male

Stiletto Fly captured by a crab spider on Sandpaper Plant - Ammonaios confusus - Male
Anza-Borrego Desert State Park, San Diego County, California, USA
October 29, 1995
Size: BL ~ 10 mm
This Stiletto Fly male was captured by a crab spider on Sandpaper Plant (Petalonyx thurberi) at Hoberg Canyon, ABDSP on the 29 Oct 1995. We collected the dead fly and brought it home to pin. Cole in The Flies of Western North America lists a fly collected in Borrego (where we found this fly) and other desert areas, Thereva semitaria. He describes it as having almond-shaped eyes (which our specimen seems to have) and whitish wings with a brown costal region. I have no way of knowing if that is the correct species--or even genus.

This is a male of Ammonaios c
This is a male of Ammonaios confusus. It is closely related to semitaria which is now in the genus Arenigena. Ammonaios confusus is a widely distributed species, but it was only described a few years ago (by Irwin and myself ;-).

 
Ammonaios confusus
Thank you so much, Dr. Hauser. I am delighted to know the actual name of this Stiletto Fly that I have been trying to learn since 1995! I will look up your publication to learn more about it.
