Flies

True flies (order Diptera) are an immense group with over 100,000 known species. They all have their hind pair of wings reduced to pin-shaped structures called halteres which act as gyroscopes to maintain balance in flight. Most feed on liquids, including nectar and blood.

The Dipterist's Forum offers a huge range of support for those interested in this group.

The families in the gallery below represent flies that are in the dipteran sub-orders Brachycera and Cyclorrhapha which are 'higher' flies, meaning later to evolve than the Nematocera which are displayed in the Craneflies, Gnats & Midges gallery. All families are displayed in taxonomic order. Note that Hoverflies (Syrphidae family) are displayed in a separate gallery.

Rhagionidae - Snipe flies

Rhagionidae are medium to large flies with slender bodies and stilt-like legs. The mouthparts are adapted for piercing and many species feed on blood, whilst others are predatory on other insects. They are typically brown and yellow flies, and lack bristles. The larvae are also predatory and are mostly terrestrial, although some are aquatic. Snipe flies in the genus Rhagio are sometimes called "down-looker" flies after their habit of perching head-downward on tree trunks.
