Bark Lice

People are noticing an interesting group of insects on trees such as crape myrtles, citrus, and oaks. These clusters of insects are bark lice or psocids. They do not harm the tree at all but are considered bark cleaners, feeding on spores, lichens, and dead animals. They will often move in groups and are therefore referred to as ‘tree cattle’. Later you may see a web around the trunks and branches that the bark lice spin for protection. This is just part of nature and worth your observation.
