Diet

Blister Beetle adults feed on leaves in the tops of a plant but are especially attracted to flowers where they feed on nectar and pollen. These beetles are mid to late summer insects, active in mid-July and early August

Reproduction

Female blister beetles lay clusters of eggs in the soil in late summer. The small, active larvae that hatch from these eggs crawl over the soil surface entering cracks in search for grasshopper egg pods. On finding a grasshopper eggmass, the larvae become immobile and spend the rest of their larval time as legless grubs . The next summer they pupate soon emerge as adults . Blister beetle populations follow closely the abundance of grasshoppers the year previous.
