The Six Wasp Special - #3 of 6 - Tachytes distinctus - male

The Six Wasp Special - #3 of 6 - Tachytes distinctus - Male
Tonopah Desert, Maricopa County, Arizona, USA
May 11, 2015
Size: 15mm
This is the third of six Wasps that I filmed on this day. This is the male and I will link the female's master image. (below) They appear to be the same species.
These are images of a Square-headed Wasp that I believe is a male Tachytes distinctus. Please note that this is a new species for the BugGuide.
