Biology and Habits
- Most species of blister beetles have one generation per year. Adults lay eggs in the soil. Larvae undergo several changes before overwintering as pseudopupae. First instar larvae seek out subterranean grasshopper egg pods (genus Epicauta) and bee eggs (genus Meloe) to complete the immature stages of development. Adult beetles are soft bodied with short wings. In some sp…
