Forensic Entomology Overview

These flashcards cover key vocabulary terms and concepts related to forensic entomology, focusing on the role of insects in determining postmortem intervals and analyzing decomposition.

Postmortem Interval (PMI)

The time that has elapsed since a person has died.

Insect Succession

The process by which different species of insects colonize a dead body over time, helping to estimate the PMI.

Carrion Beetles

Insects that are attracted to dead bodies and are also predators of the maggots feeding on the corpse.

Cheese Skipper Flies

Insects that arrive later in the decomposition process and are known for their jumping ability.

Forensic Entomologist

A specialist who studies insects to aid in legal investigations, particularly in estimating time of death.

Rate of Development

The speed at which insects develop from egg to adult, which is influenced by environmental temperatures.

Maggots

The larval stage of flies, which feed on decomposing tissues and are crucial in forensic entomology.

Life Cycle of Blow Flies

The developmental stages of blow flies, which can range from egg to adult in a matter of days, depending on temperature.

Optimal Temperature Range

The temperature range (typically between 70-80°F) where blow flies develop most efficiently.

Myiasis

A condition where maggots infest living tissue, often leading to necrosis, especially in immobile individuals.

Medical Grade Maggots

Sterile maggots used in medical settings to clean wounds by consuming only dead tissue.
