HORTICULTURE

Detailed explanation-1: -The first type of insect to arrive at a dead body is usually a blowfly (Calliphoridae), attracted by body fluids and gases. It lays its eggs within two days after death, so its stage of development-egg, larval stages, prepupal or pupal stage, adulthood-will suggest how long the corpse has been lying undetected.

Detailed explanation-2: -Insects colonize remains in a specific pattern, usually laying eggs first in the facial orifices, unless there are wounds, in which case they will colonize these first, then proceed down the body. If the maggot activity is centred away from the natural orifices, then it is likely that this is the site of a wound.

Detailed explanation-3: -Blowflies are important because they are typically the first insects to colonize a body after death. Shortly after death, blowflies discover the remains, oviposit, and feed on the remains.

Detailed explanation-4: -The underlying principle is as follows: Certain species of flies lay their eggs in the tissue of a corpse as early as one to two hours after death. A few days later, maggots hatch and grow in size with each passing day.
