Title: Red bugs have appeared on my Texas mountain laurel
Answered by: Guy Thompson
QUESTION:
What should I do about the red bugs on my mountain laurel?ANSWER:
The red bugs are most likely Lopidea major. These lnsects can disfigure the TX mountain laurel foliage, but they do not cause serious damage. They are difficult to eliminate with insecticides because they are members of the True bug order, which feed on foliage by piercing the leaves and sucking out the contents. They thereby avoid insecticides sprayed onto the leaf surfaces. And the waxy leaf cuticle prevents the plant to efficiently take up systemic-type insecticides. It is probably best to leave them alone or, for cosmetic purposes, spray them off with a hose. In any case, they willl disappear in time, leaving the plant unharmed.
