S. American Longhorn Beetle (Prionacalus cacius).
Sporting both extremely long antennae like longhorn beetles and mandibles like stag beetles, these guys have it all! Unfortunately, I couldn’t find much information about them, so they must not be well studied.
Insects come from entomological supply companies. They are farm-raised by locals dedicated to conservation.
Art is 6" x 6". Comes with picture wire mount on the back for hanging. I also sell small easels if you prefer to display them to standing in your curio cabinet.
