Housefly in the context of "Pupae"

A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops.

Some animals are disliked because they bite or sting; wolves, snakes, wasps, ants, bees, bed bugs, mosquitos, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food; beetles, which tunnel into the woodwork; and other animals that scuttle about on the floor at night, like rats, mice, and cockroaches, which are often associated with unsanitary conditions.

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, hoverflies, and blowflies, rather than larvae of the Nematocera, such as mosquitoes and crane flies.

Musca is a genus of flies. It includes Musca domestica (the housefly), as well as Musca autumnalis (the face fly or autumn housefly). It is part of the family Muscidae.

The Nematocera (nemato+cera meaning "thread-horns") are a suborder of elongated flies with thin, segmented antennae and mostly aquatic larvae. This group is paraphyletic, containing all flies except for those of the suborder Brachycera (the name meaning "short-horns"), which includes species such as the housefly or the common fruit fly. Thus, the equivalent clade to Nematocera would be the whole of Diptera, with Brachycera as a "subclade". Families in Nematocera include mosquitoes, crane flies, gnats, black flies, and multiple families commonly known as midges.

The nematoceran imago typically have elongated bodies and legs, and many species have relatively long abdomens. They also have fairly long, fine, finely-jointed antennae; in many species, such as most mosquitoes, the female antennae are more or less threadlike, but the males have spectacularly feather-like or plumose antennae.
