I took a photo of just one of the numerous clusters of unidentified insects just sitting in these clusters, not moving too much, on our magnolia tree. If you zoom in on the photo you can see two distinct looking insects, possibly the male and female? We first noticed them about 3 days ago and they are still there, not doing much except huddling in these large masses. Can you tell me what they are and if they are dangerous? I live in Olean, NY.

Dear Pat,
These are Barklice, and they are sometimes called Tree Cattle.  They are benign insects that feed on lichens, and they will not harm your trees.  The striped individuals are immature nymphs and the dark individuals are winged adults.

Thanks so much, Daniel!  We’re relieved to hear they’re harmless critters.  You da man!  Thanks for the great vice you provide.
