Mystery bug on red cedar
November 16, 2009
These pictures were in Eastern Long Island in August. They were on eastern red cedar in a “grove”. Trees had cedar quince rust, even on trunks. I think they may be involved in disease spread. Move very fast in “herd” like fashion. Third image is azalea lacebug, thought you might be interested..it shows the helmet and cowl fairly clearly!

Dear Dr. Andy,
The Barklice you wanted identified are perfectly harmless. They are sometimes called Tree Cattle. The pictured individuals are immature and the adults will have wings. Thanks for also including the photo of the Azalea Lace Bug.
