Barklice

Groups of barklice can be found on tree trunks where they feed on lichens, decaying organic matter, dead insects, molds, fungi, and pollen. They do not harm living plants, but they may be found around wounds or damaged areas.

Barklice have very long antennae, dark stripes across the body, and a bulging “forehead” located between the antennae (Figures 1 & 2). Adults have wings but the nymphs do not. There is no need for control.
