The Striped Blister Beetle uses familiar warning colors to keep predators at bay. Insects and people who do not heed the warnings suffer for it.
When threatened, this blister beetle secretes an acidic yellowish fluid onto its legs. Predators and people that come into contact with this fluid are burned by this substance and blisters form in the area of contact.
Their habitat includes gardens, parks and farm fields. Adults eat potatoes and other garden plants, making them a potential pest to backyard gardeners.
Larvae feed on buried grasshopper eggs and overwinter in the ground. This diet keeps crop-destroying grasshopper populations in check, making them beneficial insects to have around to farmers and backyard gardeners.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
