Vegetable Insects

Hornworms are large green caterpillars, often found feeding on tomato leaves.

This copper colored beetle resembles the Mexican bean beetle but is larger and has 14 spots as compared to 16 spots. It feeds on the tissue between leaf veins. Squash, cucumber, pumpkin, and squash may all serve as host plants.

The larvae of the spotted cucumber beetle can injure vegetable seedlings.

Seeds that fail to germinate or seeds that are damaged or have a white maggot inside may be infested with seedcorn maggots. This is most common on warm–season crops with large seeds such as corn, bean, pea, and melon.

Roots with nodules or bumps may have root-knot nematodes.

Root aphids are sometimes found feeding on roots of beans and corn.

Potato tuberworms feed between leaf surfaces and bore into stems of potato plants.

Small holes in bean leaves may be caused by Mexican bean beetle chewing.

Flea beetles are shiny black beetles that jump and make tiny holes in vegetable leaves.

These orange and black bugs are pests on broccoli, cauliflower, and kale.
