Barklice - Cerastipsocus trifasciatus

Barklice - Cerastipsocus trifasciatus
Ozark Mountains, Searcy County, Arkansas, USA
June 18, 2007
Size: 3mm
Circling around and around a rock in our flower bed border ... another congregation on a nearby rock in the border ... assume they came out of the flower bed ... seem to be in various stages of wing development ... we'd just received a couple of thundershowers that dumped a couple inches of rain.

Cerastipsocus trifasciatus
This is really interesting, these are adult and nymph Cerastipsocus trifasciatus; Family Psocidae. I have never seen them in the wild before but based on the photos in Bug Guide they seem to practice the same communal grazing behaviour that I often see in their nearest relative C. venosus. C. venosus nymphs have yellow and brown stripped abdomens and C. trifasciatus nymphs can be ID by their red heads and white and brown stripped abdomens.

These are barklice
in the order Psocoptera and the family Psocidae. They are surprisingly pretty! These "herds" seem pretty common, but I've never seen them like that. :-(

Nice photos!

Thanks for the ID, Graham
As far as I can tell, these critters spent all night going around and around that rock. At least, they were still at it the next morning. However, once the sun started hitting that flower bed, it didn't take them long to disappear again ... Marvin.

Anyone know whether some
of the images currently posted under Psocidae are actually Cerastipsocus venosus?

I certainly don't,
but the ones under Cerastipsocus venosus do look exactly the same as everything else in Psocidae.
