They arrive at corpses slightly later than the pioneer blowflies, but the eggs hatch in the uterus of the female, before she lays them, with the result that the larvae are deposited directly on the body.
What insects help with decomposition?

What are the five stages of decomposition?
Five general stages are used to describe the process of decomposition in vertebrate animals: fresh, bloat, active decay, advanced decay, and dry/remains. The general stages of decomposition are coupled with two stages of chemical decomposition: autolysis and putrefaction.
What does human decomposition smell like?
The gases and compounds produced in a decomposing body emit distinct odors. While not all compounds produce odors, several compounds do have recognizable odors, including: Cadaverine and putrescine smell like rotting flesh. Skatole has a strong feces odor.
What happens to a body in a sealed casket?
If the coffin is sealed in a very wet, heavy clay ground, the body tends to last longer because the air is not getting to the deceased. If the ground is light, dry soil, decomposition is quicker. As those coffins decompose, the remains will gradually sink to the bottom of the grave and merge.
