5 major types of arthropods

Calliphoridae, sacrophagidae, muscidae, silphidae, dermestid, staphylinidae

6 families of insects

Calliphoridae

Shiny blue/green, early arrivers, feed on bloat/active decay, consumption, recycling, dispersion carrion nutrients

Sacrophagidae

feed on organic matter, larviposits

Muscidae

feeds on active remains if has to, but prefers not to

Silphidae

burying and carrion beetles

Dermestidae

Make more rich fertilizer
