During the first instar stage the eggs hatch out into maggots (larva) and start feeding on the corpse and are 5mm long. During the second instar stage‚ (2-3 days) the maggots continue to

fertilized egg‚ once met with the free-floating sperm released by males‚ develops into a free-swimming blastula embryo in as few as 12 hours. Initially a simple ball of cells‚ the blastula soon transforms into a cone-shaped echinopluteus larva. In most species‚ this larva has 12 elongated arms lined with bands of cilia that capture food particles and transport them to the mouth. In a few species‚ the blastula contains supplies of nutrient yolk and lacks arms‚ since it has no need to feed. During early

way to reproduce and affect the farmer’s crops. Northern corn rootworm has a unique life cycle. The female insects lay eggs in late August. Those eggs then hatch starting in May. After the egg hatches the insect is in what we call a larva stage. The larva for a Northern corn rootworm is a worm and feed on roots. That is why they are called rootworm. The damage to the roots can cause the plant tip over because it has poor structure and it can affect the crops ability to bring up the nutrients

Drosophila melanogaster is a fruit fly‚ about 3mm in length‚ and it is the insect that flies around spoiled fruit. A model organism has these traits: short life cycles and rapid development‚ small average size‚ big population‚ and fast reproduction (NCBI). Drosophila melanogaster meet all of the criteria for being a model organism. Also‚ fruit flies were used because they are very easy to handle and they require minimal resources to survive‚ as opposed to other organisms that might need more food
