I live in St. Augustine, Florida. Today (December 23) I noticed clusters of small, black insects on one of the two crepe myrtles in our back yard. I took a picture to try to look it up online and I noticed another type (or possibly babies of the first?) of insect in the group. My parents and I want to know if this insect is harmless or if it’s something we should worry about.

  1. We found several groups of these on the branches of our magnolia tree. This morning they were in pods, not moving. Some were molting. Yesterday at dusk they were streaming along a few of the branches like ants.
