Blister Beetles

Blister beetles, in the Meloidae family of beetles, earned their name from their defense system. They secrete a caustic chemical, cantharidin, which is an effective repellent for predators and can cause blisters on the skin when the beetles are handled.

The bodies of blister beetles are usually long and slender and often bi-colored. Their antennae are threadlike or beadlike.

Blister beetles use their strong jaws to chew the flowers and foliage that they feed on.

The bright red and black pattern on the blister beetle pictured above is a warning sign of their toxicity to predators.

Beetles, forming the largest order of insects with nearly 400,000 identified species, account for nearly 40% of all insects. So I guess it’s no surprise that my collection of beetle images is one of my largest!
