![]() Cetonine larvae, similar to those of geotrupids and lucanids, are often short, less C-shaped than most scarabaeids, hairy, active, and capable of locomotion on their backs through movement of body segments. Scarabaeid larvae are soft-bodied, thick, strongly C-shaped, and somewhat flattened beneath and round above. Larvae of the plant-feeding epilachnines often are yellow with black bristles. Coccinellid larvae-flattened, broad in the middle, and tapering at the back-sometimes have a few low projections (tubercles) bearing short hairs and are often strikingly coloured with red or yellow and black. Larva of the seven-spotted ladybird beetleĭermestid larvae, somewhat tapering and cylindrical, have whorls of short bristles and some longer ones and resemble hedgehogs or porcupines.

In warm weather when there are plenty of invertebrate decomposers, a small animal the size of our Hilton Pond frog may disintegrate almost completely in a week or so, leaving only bone and nearly indigestible dried skin to mark its passing.Īs unappetizing as this tale might seem, we should always be thankful for flies and carrion beetles and hitchhiking mites. Ants and wasps may get in on the feast, and much larger Black Vultures (above right) and mammalian scavengers will pick at the carcass, either consuming the tasty parts or breaking everything else into smaller pieces more accessible to insects. Other inch-long insects known as Rove Beetles often arrive and use their strong biting mouthparts to tear at the flesh of a dead animal. Of course, the decomposition story doesn't stop with carrion beetles, mites, and flies. Meanwhile, back at the old carcass, immature mites left behind may have linked up with beetle pupae underground thus, when a pupa opens after a few months and releases an adult carrion beetle, the new beetle already has its own complement of mites to transport on its maiden visit to a freshly dead animal. The beetle larvae eventually fall to the ground and form subterranean pupae, at which point the female beetle flies off to find another corpse-taking some of her mites with her. It's even been suggested that some mites perform maintenance on carrion beetles themselves, cleaning off bacteria the host insects are bound to pick up as they explore a carcass.Īfter a female carrion beetle's eggs hatch, her larvae dine on the corpse as long as food lasts. Carrion beetles return the favor by hauling the non-flying mites to the next banquet of fly eggs when yet another animal dies. Second, after being transported to a corpse by carrion beetles the mites quickly get down to the business of eating fly eggs and even small maggots, thus reducing the fly population and creating more space and food for beetle larvae. First, the mites demonstrate "phoresis," the symbiotic relationship in which a non-parasitic organism hitches a ride on another. or perhaps a related genus-we DO know what roles they play in our decomposition drama. ![]() ![]() Although we weren't able to specifically identify the mites-they could be Poecilochirus spp. ![]()
