HORTICULTURE

Detailed explanation-1: -From the moment of death flies are attracted to bodies. Without the normal defences of a living animal, blowflies and house flies are able to lay eggs around wounds and natural body openings (mouth, nose, eyes, anus, genitalia). These eggs hatch and move into the body, often within 24 hours.

Detailed explanation-2: -Adult female blow flies arrive within minutes to lay eggs on a cadaver. Each deposits about 250 eggs in the natural openings of the body and open wounds. The eggs hatch into first-stage maggots within 24 hours.

Detailed explanation-3: -Blow flies have a keen sense of smell and this means that some species can detect a dead body from up to 16 kilometres away. They are one of the most important groups for estimating the PMI because of how fast they can arrive at a body. In some cases, they’ve been known to turn up within just 10 minutes!
