Found these bugs on a ficus tree trunk in San Diego, CA. There was one group of the bigger bugs, and anther group with a few of the large bugs that seemed to be herding the little striped bugs. The bigger bugs were about 1/4” long, maybe less.
Can you tell me what they are, and what they are doing.
This is our second posting this week of an aggregation of Barklice from San Diego. We are not certain of the species because this looks like an allegedly eastern species, Cerastipsocus venosus, that are commonly called by the Tree Cattle. Tree Cattle are benign insects that feed on lichens and pose no threat to the tree, garden or gardener. We don’t know if the eastern species has been accidentally introduced to the west, if this is a heretofore unknown species or if there is just little documentation on the presence of this insect in Southern California. Time will no doubt provide some revelations.
