maggot

A maggot is the larval stage of a fly, typically from families such as Calliphoridae (blowflies) and Muscidae (houseflies). Maggots are legless, worm-like creatures that vary in size depending on species and age.

Maggots hatch from eggs laid on decaying organic matter, carrion, feces, or sometimes wounds. The larval stage usually progresses through three instars, during which the organisms feed voraciously before entering the pupal stage. Development from egg to adult is influenced by temperature and can range from a few days to several weeks. Adults emerge to mate and reproduce, continuing the life cycle.

Ecology and human relevance: Maggots are important decomposers, helping recycle nutrients from dead material. Some species colonize living tissue and can cause myiasis in animals or humans. Maggot growth on wounds can indicate an infestation. In medicine, sterile larvae of certain species, notably Lucilia sericata, are used in maggot debridement therapy to clean necrotic tissue and promote healing.

Uses and implications: Maggots are used as fishing bait and are studied in forensic entomology to estimate the postmortem interval, based on larval development rates at various temperatures. They can also pose as pests in food storage and unhygienic environments, underscoring the importance of sanitation and pest control.

Habitat: Maggots are commonly found in rotting organic matter, manure, carrion, feces, and, in some cases, wounds. They are typically temporary visitors that appear where flies lay eggs.
