The first insects to be attracted to a corpse are the _____. blowfly maggots blowfly larvae blowfly pupae blowfly adults looking
Alla [95]

Answer:

Blowfly adults looking for a place to lay their eggs

Explanation:

Blowfly adults are attracted to the gases and fluids of a dead body and usually lay their eggs on a dead body within the first two days after death.

The eggs then turn into larvae then enter pupal stages and then become adults themselves. Forensic entomologists can determine how long a body has been dead by the stage of development of the blowfly with the ambient temperatures that have been present.
