Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
within minutes of a death, insects arrive to the warm body and:
A
begin to feed on it
B
lay their eggs on it
C
colonize it as their new home
D
None of the above
Explanation: 

Detailed explanation-1: -The first insects to arrive at decomposing remains are usually Calliphoridae, commonly referred to as blow flies. These flies have been reported to arrive within minutes of death or exposure, and deposit eggs within 1–3 hours.

Detailed explanation-2: -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. The life cycle of a fly from egg to maggot to fly takes from two to three weeks.

Detailed explanation-3: -Blow flies and flesh flies are the most useful crime scene insects for determining the postmortem interval, or time of death. Through laboratory studies, scientists have established the developmental rates of necrophagous species, based on constant temperatures in a laboratory environment.
