The study of insects in civil or criminal investigations.

Parasitic infestation of larvae in living humans, such as blowflies.

Sequential stages a body undergoes after death, impacting insect presence.

Predictable pattern of insect species colonizing a decomposing body.

Legal rule for evaluating the reliability of expert testimony in court.

Female blowflies lay eggs in moist tissues, usually in clusters.

Blowflies undergo complete metamorphosis: egg, larva (instars), pupa, adult.

Larvae have 3 instar stages with increasing size and duration.

Larvae have a slender anterior and rounded posterior with spiracles for breathing.

Larvae search for a dry area to pupate, where they form a hard case and transform.

Small flies that often appear on wrapped bodies and feed on decomposing flesh.

Beetles that arrive after flies to eat larvae and bury flesh with their eggs.

The process of laying eggs by insects, which is affected by environmental conditions.

Maggots that gather in large groups, which can increase local temperature and speed development.

Blowflies are key indicators used to estimate the postmortem interval (PMI).

Beetles that feed on fly eggs and larvae, aiding in decomposition.

Beetles that consume dried remains of decomposed corpses.

Factors like temperature and humidity that influence insect development and PMI estimation.

The final larval stage of blowflies, indicating a certain time frame for PMI.

Insects collected at a crime scene help forensic scientists estimate the time of death.
