Plant bug is a leaf feeding pest common on Honeylocust trees. Plant bug causes disfigurement of new leaves, shoot growth, and can contribute to tree stress. Repeated annual infestations can cause accumulation of deadwood in tree (due to reduced photosynthesis), excess leaf litter, and vector diseases and viruses.
What it is:
-Very common leaf feeding pest on Honeylocust trees
Why:
