photographing and learning about wildlife
Bodies elongate-cylindrical and black overall. The head is narrower than the thorax. Provided we are correct with the family, which I think we are, given the pictures I have seen online, a characteristic of these beetles may be that they are also able to produce acoustical signals, in some cases more than many vertebrates. Adults produce the sounds by rubbing the upper surface of the abdomen against the hind wings. The larvae produce the sounds by rubbing the third leg against a striated area on the coxa of the second leg.
