AZ BugGuide Gathering Micropeza - Micropeza bisetosa

AZ BugGuide Gathering Micropeza - Micropeza bisetosa
Off Ruby Road, Pena Springs area, Pajarito Mountains, Santa Cruz County, Arizona, USA
July 27, 2013
During our mid-day field stop on the 3rd day of the AZ BugGuide gathering, while exploring near a small side-canyon creekbed, Troy Bartlett mentioned to me having just seen a micropezid in a nearby field, and I excitedly asked it he could direct me to it. I had read about micropezids but never seen one.

Troy said he thought he might be able find it again, and walked about 60 feet away into a large non-descript area of grass and herbs with few distinguishing landmarks...what looked to me like a difficult place to try to refind a tiny fly. But calm, steady, keen-eyed Troy proceeded to search, and in a short while relocated the quarry. I was delighted, and eagerly commenced photographing the thin little stilt-legged fly.

After a few shots the micropezid flew and I lost track of it. I don't remember if Troy found "it" again or I did (I vaguely recall the former)...but when studying the photographs long afterwards, the 2nd micropezid (found within minutes and feet of the 1st) turned out to be a different species! That 2nd species appears in the post below:



The one in this post keys clearly, in both Merritt & James(1) and Cresson (1938), to subgenus Neriocephalus (see here) and species Micropeza bistosa (see here). The two notopleural bristles (visible in last image of series) indicate the subgenus, and the presence of a black arista and the two shining lines on the vertex between the inner and outer vertical bristles (again, see last image) indicates species bisetosa. The description in Cresson fits well, and the locale here is within the range...in fact, Merritt (1972) lists "Santa Cruz Co., Ruby" as an AZ location for M. bisetosa.
