Texas Beetle

This beetle has a light brown elongated oval body between four and eight millimetres long. The head is slightly wider than it is long and there are globular, protruding eyes. The antennae have ten segments, the distal six expanded on one side to form pectinate clubs, though these are less developed in the female. The prothorax is wider than it is long and widest posteriorly. The elytra have nine weakly impressed punctate striae and are broadly rounded at the posterior. The hind wings are as long as they are wide and have oblique, apically dividing, linear sclerites. The male beetle is smaller than the female and is much the same width for most of its length whereas the female is broadest in the posterior third of its length. The larva is pale coloured, up to fifteen millimetres long, flattened and broadly ovate. The head is dark and much narrower than the prothorax. The antennae and legs are well developed. There are fairly long lateral lobes lined with elongate feathery lobules on all the thoracic segments and on the first eight abdominal segments. The upper side is armed with heavily sclerotized, scale-like setae. …

B. fulva occurs in Mexico and in the southern United States in the states of Arizona, California, Colorado, New Mexico, Texas and Utah.
