    Psocid Barklice - (Cerastipsocus venosus)

    Psocid Barklice nymphs travel in large groups and look troublesome, but their diet of exterior plant material make them good tree cleaners.

    Staff Writer (8/2/2017): The term 'lice' tends to make people uneasy, but these are not the blood-sucking lice normally associated with the human body. Apart from their small size, they have nothing in common with human lice. Psocid Barklice are chewing insects and they do a stand up job of eating fungus, lichen, algae, dead bark and other plant debris off of tree trunks. They prefer damp areas where the humidity helps foster growth and degradation of their food. Their nymphs often congregate around an area of the tree with algae or lichens on it and they remove that patch, moving on to another. Like most large groups of adolescents, they tend to cause apprehension in observing adults, but Psocid Barklice are harmless. They do not sting or bite people and they do not harm the tree they are gleaning from.

    Look for them in forests and wooded areas. Conifers and deciduous trees are both likely to have them if they are laden with growth on the exterior trunk. They are active from spring to autumn in colder states and provinces, and yearound in wamer southern areas. Adults are winged and may be seen near nymphs.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
