The Diptera are flies with only a single pair of wings, the second pair being reduced to halters (knobs on short stems). True flies can thus be distinguished from other flying insects, such as mayflies, dragonflies, damselflies, etc. Some true flies, however, have become secondarily wingless.
The Diptera are one of the largest insect orders, containing an estimated 240,000 species worldwide. They are also of significant ecological, medical, and economic importance.
As in most island faunas, the Diptera of the Galapagos are unbalanced or disharmonic compared to the mainland fauna.
The diversity and ecology of the Diptera in the Neotropical source area determines which of them can and cannot not arrive and survive in Galapagos. For example, the absence or poor representation of many aquatic groups is because most of the islands lack permanent fresh water.
