Detailed explanation-1: -Wasps are insects that consume the larvae and eggs of flies. In this case, they usually arrive after the blowflies.

Detailed explanation-2: -Blowfly larvae have three larvae life cycle stages called the first, second, and third instar larvae, and it is the third form that is commonly known as a maggot. The stage of life where an insect transforms from its immature form as a larva to its adult form after metamorphosis.

Detailed explanation-3: -The eggs hatch into first-stage maggots within 24 hours. These feed and then molt into second-stage maggots, which feed for several hours, and then molt into third-stage maggots.

Detailed explanation-4: -Adult blow flies feed on a variety of materials, but the larvae of most species are scavengers that live on carrion or dung. The adults lay their eggs on the carcasses of dead animals, and the larvae (maggots) feed on the decaying flesh.

Detailed explanation-5: -The correct answer is B. The spiracle slits of the blowfly larva changes as it goes through the different larval stages: instar 1, instar 2, and instar 3. In instar 1, there is only one spiracle slit near the anus of the larva, whereas there are two spiracle slits formed during instar 2.
