The presence of blowflies attracts predators such as skin beetles, mites, ants, wasps, and spiders, to the cadaver, which then feed on or parasitize their eggs and larvae. Vultures and other scavengers, as well as other, large meat-eating animals, may also descend upon the body.

biochemical pathway - chain of chemical reactions that occur in living things to produce a chemical compound. Fuller, M.E. 1934. The insect inhabitants of carrion: a study in animal ecology. Council for Scientific and Industrial Research. Bulletin No. 82. 63 pp.A decomposing body significantly alters the chemistry of the soil beneath, causing changes that may persist for years. Purging releases nutrients into the underlying soil, and maggot migration transfers much of the energy in a body to the wider environment. Eventually, the whole process creates a ‘cadaver decomposition island,’ a highly concentrated area of organically rich soil. As well as releasing nutrients into the wider ecosystem, the cadaver also attracts other organic materials, such as dead insects and faecal matter from larger animals.

Bacteria break down tissues and cells, releasing fluids into body cavities. They often respire in the absence of oxygen (anaerobically) and produce various gases including hydrogen sulphide, methane, cadaverine and putrescine as by-products. People might find these gases foul smelling, but they are very attractive to a variety of insects. It might take a little bit of force to break this up,” says mortician Holly Williams, lifting John’s arm and gently bending it at the fingers, elbow and wrist. “Usually, the fresher a body is, the easier it is for me to work on.” Morovic-Budak, A. 1965. Experiences in the process of putrefaction in corpses buried in earth. Medicine, Science and the Law. 5: 40-43. The build up of gas resulting from the intense activity of the multiplying bacteria, creates pressure within the body. This pressure inflates the body and forces fluids out of cells and blood vessels and into the body cavity. Insect activity

Stage 5: Butyric fermentation - 20 to 50 days after death

The so-called gut microbiome is one of the hottest research topics in biology at the moment. Some researchers are convinced that gut bacteria play essential roles in human health and disease, but we still know very little about our make-up of these mysterious microbial passengers, let alone about how they might influence our bodily functions. On an even smaller scale, enzymes inside individual cells are released when the cell dies. These enzymes break down the cell and its connections with other cells. Insect activity

This change is a result of drying, and the activities and by-products of the corpse fauna. Different groups of animals find the corpse attractive at different stages of decomposition and the resultant change in the animal community is called a succession.Insects can be useful for estimating time of death of a badly decomposing body. In theory, an entomologist arriving at a crime scene can use their knowledge of insects’ life cycles to estimate the time of death. And, because many insect species have a limited geographical distribution, the presence of a given species can link a body to a certain location, or show that it has been moved from one place to another.
