chilly bugs
Hey Bugman, these little critters were obviously chilly one morning. After the sun came out they were gone, then back the next morning. We are in West Tennessee. Don’t know where to look them up since we have no clue what they are. Thanks. As always, love your informative site.

Hi Richard,
We wrote to Eric Eaton for help identifying your aggregation. Here is his response: “Wow! Spectacular images of barklice, order Psocoptera, family Psocidae. Also known as “tree cattle,” especially in the nymphal stage. Some species create webbing on the bark, but I have never heard of them becoming pests. Pretty sure they feed on fungal spores and the like. Eric “
