José once opened some of
the bunches produced by Cryptocephalus vittatus. In them he found a
single egg each. The bunches are made of fecal pellets by
which the female covers her eggs egg.
The brown, coarse surface of an egg case serves as a camouflage on brown bark. Beside, the longish, bent and pointed ends of the pellets give the egg a good grip on the bark and makes it stick. The larvae hatching keep their egg case and wear it as a coat for their own protection. |
