Bark lice

6596.      I found these beetle juice and looking bugs around my Hammock lines. Never seen them before are they new? They had a weird sway to them. Any info would be great thanks. Tiny, Ontario. Canada

Number 6596. These are bark lice (Psocodea: Psocidae); likely Cerastipsocus venosus, a species often referred to as ‘tree cattle.’ They do not cause any harm as they feed on fungi, algae, lichen, dead bark and other materials that occur on tree trunks and large limbs;  Click here for details on their life cycle.
