Bark Lice on Tree

During your winter garden activities, you may notice a group of insects massed together on tree trunks.  If you touch the area, the insects will scatter.  These are bark lice or psocids which are considered beneficial as bark cleaners.  They do not harm the tree but are an interesting organism common in landscapes.
