Found this on crepe myrtle tree whilst pruning today–they traveled together in 20-30 bug groups, moving then stopping on the bark. What is this?

These are benign Barklice. Home gardeners may find the presence of aggregations of Barklice or Tree Cattle as they are commonly called, alarming because generally insects found in large groups on plants are injurious, Barklice will not harm your crepe myrtle tree. Barklice feed on lichens on tree bark and fence posts. We hope future encounters do not meet with Unnecessary Carnage because it appears the Barklice in your image have succumbed to pesticide spray.
