1. what is the typical order in which insects begin to arrive on human remains?

Typically, blowflies (Calliphoridae) are the first to arrive, and are attracted to body fluids and gasses. They usually lay their eggs within two days after the body's death, and the stage of their life cycle when a body is found is a fair indicator of how long a body has lain undiscovered. As the body starts to decay, flesh flies (Sarcophagidae) are attracted to the decaying flesh and arrive next. Then, as the corpse begins to dry out and become too difficult for the maggot larvae to consume, different types of hide and carcass beetles begin to arrive. Some of these include carrion beetles (Silphidae) and Rove beetles (Staphlynidae) and have chewing mouthparts to better deal with the dried flesh, skin, and ligaments. Finally, moth larvae and mites, which feed on the hair, will finish off the process of consumption.
