Blow Fly Maggots
Blow fly larvae are also known as maggots. Measuring 9 to 22 mm in length, maggots are equipped with hook-like mouthparts and spiracles for breathing. They are soft and pale in color and appear similar to worms or grains of rice. Each body segment of the blow fly maggot has a median row of fleshy tubercles that resemble hair.
Blow fly maggots are generally seen near dead animals. Blow fly eggs are laid in rotting meat, where maggots feed and complete their development before seeking a dry location within which to pupate. After maturing, larvae create outer skins, known as puparia, that look like rat droppings or cockroach egg cases. Pupae develop within the puparium, maturing into adult blowflies.
