The Q&A Archives: White "wormy-like" Designs Running Through Green Bean Leaves

Question: I have white, squiggly looking lines running through my green bean plant's leaves. They seem to be curling up and wilting quickly as well. Can you please tell me what this is and how to treat?

Answer: It sounds like some type of leafminer, which is the larval form of many different flies, moths and beetles. Sometimes, if you hold the leaf up to the light, you can seen the larvae at the end of the line. The easiest method of control is to remove the affected leaves or to crush the grub.
