Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies may have been among the evolutionarily earliest pollinators responsible for early plant pollination. Flies can be annoyances especially in some parts of the world where they can occur in large numbers, buzzing and settling on the skin or eyes to bite or seek fluids. The possession of a single pair of wings distinguishes most true flies from other insects with “fly” in their names. Common house fly, Musca domestica. The phylogenetic position of Diptera has been controversial. Lepidoptera, Coleoptera, Hymenoptera and Diptera, and it is the relationships between these groups which has caused difficulties.

Diptera has been grouped with Siphonaptera and Mecoptera in the Antliophora, but this has not been confirmed by molecular studies. The Nematocera are recognized by their elongated bodies and many-segmented, often feathery antennae as represented by mosquitoes and crane flies. The Brachycera have rounder bodies and much shorter antennae. Subsequent studies have identified the Nematocera as being non-monophyletic with modern phylogenies placing the Brachycera within grades of groups formerly placed in the Nematocera. The construction of a phylogenetic tree has been the subject of ongoing research. The following cladogram is based on the FLYTREE project.

Imago of Blepharicera fasciata as Asthenia fasciata in Westwood 1842, plate 94. Clogmia Albipunctata or moth fly. Hermetia illucens Black soldier fly edit1. Mosca cernidora de la grosella. Flies are often abundant and are found in almost all terrestrial habitats in the world apart from Antarctica. They include many familiar insects such as house flies, blow flies, mosquitoes, gnats, black flies, midges and fruit flies.

The suborder Nematocera include generally small, slender insects with long antennae such as mosquitoes, gnats, midges and crane-flies, while the Brachycera includes broader, more robust flies with short antennae. Many nematoceran larvae are aquatic. There are estimated to be a total of about 19,000 species of Diptera in Europe, 22,000 in the Nearctic region, 20,000 in the Afrotropical region, 23,000 in the Oriental region and 19,000 in the Australasian region. Brachycera are ecologically very diverse, with many being predatory at the larval stage and some being parasitic. In wet and colder environments flies are significantly more important as pollinators. Compared to bees, they need less food as they do not need to provision their young.
