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.
