Blister Beetles

Blister Beetles

Although markings vary greatly depending on the species, blister beetles are easily identified by their physique: the middle section of the body is noticeably smaller than the head or abdomen. The majority of these pests are well under an inch long.

Target: Many flowers and vegetables, especially those belonging to the tomato family.

Damage: Leaves are chewed. When large populations of beetles appear suddenly, damage can be serious.

Life cycle: Adults lay eggs beneath the soil, where the newly hatched grubs feed on grasshopper eggs. The grubs remain underground in a dormant state for up to 2 years, then become active, pupate, and emerge as plant- feeding adults in late spring or early Summer.

Notes: Use gloves if hand picking these beetles, since they exude a substance that can cause painful blisters
