Roosting cluster of Vespid wasps ?? Idaho, July, 5000ft, -
Nr. Arco, Idaho, Moore , Lost River Range County, Idaho, USA July 13, 2007 Size: c.1"
I know they are "yellowjacket" type wasps of the Vespid.family, but I cannot identify the species at all. They seemed to be unusually black and white with yellow legs, and a decided violet blue tone to their wings.
They simply clustered at sundown in this clump on a single exposed dried weed stalk perhaps 30" high, in an open field c.20 feet away from a moist irrigation ditch with scraggly cottonwoods (spp). This was near Arco in Idaho, at an elevation of perhaps 5500ft, in early July. They remained in this clump of perhaps 50 - 100 individuals through the night until the sun warmed things up, then they all left to do waspish things during the day. I saw no sign of a queen or any mating or nest building behaviour. Every night they returned, for the week we were there, though towards the end they were definately fewer, though we tried not to disturb them.
