Diathrausta 1 (of 2) ...

Looks like The Padelfords, Balabans & Margarethe all got a shot of these. I foto'd one each night, in different locations, and the difference I note, as did jane & john is in the shoulder area. My Diathrausta 1 was taken at Santa Rita Experimental Range, Florida Station on 7/25/13. My Diathrausta 2 was taken at Madera Canyon on 7/26/13. 1 looks more like Margarethe's with the shoulder area filled in with orange color and 2 looks more like The Padelfords & Balabans with 2 stripes/bars, not filled in with orange marking.

Amount of orange markings varies greatly, but that's what gave it the common name. In the east we get some without orange markings. Maybe some day they will be declared two species. (no rsvp, thanks).
