Ironclad Beetle

Zopherus nodulosus haldemani


Ironclad beetles range in size from about ½ to 1 1/4 inches in length. Some of the species are entirely black but some are strikingly marked with white and black patterns, which can make it very difficult to locate them on the trunk of trees. These beetles are unique in that they have no hind wings and their elytra (front wings) are fused together. Thus they do not fly but crawl from place to place. Its exoskeleton (integument) is extremely hard.

The exoskeletons of these beetles is extremely thick, hence their name. This species is living jewelry in Mexico where the beetles are decorated by jewelers.

From what I have read about the hardness of their exoskeleton, it really is.
