Maggot vs. Worm — What's the Difference?

A maggot is the larva of a fly (order Diptera); it is applied in particular to the larvae of Brachycera flies, such as houseflies, cheese flies, and blowflies, rather than larvae of the Nematocera, such as mosquitoes and crane flies. A 2012 study estimated the population of maggots in North America to be in excess of 3×1017.
