I found no common name other than the familiar name: “Longhorn Beetle.” This remarkably colored beetle is in the Prioninae, a subfamily of Cerambycidae (long-horned beetles). True to its name, its antennae are longer than its body, This beetle was 65 mm long which is the maximum size they reach. Its defense isn’t limited to the impressive 2 cm long mandibles, the head, prothorax and leading tip of the elytra are armed with very sharp spines. The surface of its entire body appears to have an iridescent metallic purple textured appearance.
Psalidognathus friendi is found in Venezuela, Colombia, Ecuador, Peru and Bolivia. The majority of the Prioninae beetles are nocturnal and are attracted to light. This one was found under a light in the Amazon rainforest of SE Ecuador. Little could be found of its habits or habitat, but the majority of the Prioninae whose biology is known are borers whose larvae feed on rotting wood or roots
I almost couldn't believe my eyes when I found this beetle. Not only was it huge, but the colors were unbelievable. Digging up information about it was a long process. There is an interesting video at the following link: https://www.shutterstock.com/video/clip-...
