These bugs were found clustered on a burgundy oxalis. Are they harmful to plants?
They dispersed quickly when I brushed them off.
These look like newly hatched Grasshoppers. We cannot be certain of the species. Grasshoppers feed on plants, and their presence in such numbers on your purple shamrocks indicates that the eggs may have been laid in the flower pot, however, it does not appear that they are feeding on the shamrock. The plant is in the genus Oxalis and the plant contains oxalic acid, which may deter insects from feeding upon it.
