Tiny round holes in leaves

Possible Causes for 

Bean Leaf Beetle

Small yellow, tan or reddish beetles, often with black spots, that chew round holes in leaves and may also scar developing bean pods.

Diamondback Moth

Small grey-brown moth; its small green caterpillars wriggle when disturbed and chew holes or “windowpanes” in leaves.

Flea Beetle

Tiny, shiny beetles that jump like fleas when disturbed. They chew numerous small, round holes in leaves, giving them a distinctive “shot-hole” appearance. Seedlings and young plants may have leaves riddled with holes.
