Summary

Curtonotidae, also known as quasimodo flies, is a small family of dipteran flies characterized by their humpbacked appearance and scavenging habits. With a global distribution, they are primarily found in tropical regions and remain understudied since the 1930s.

Physical Characteristics

Small to medium-sized flies, approximately 7 mm in length. They are grey to dark brown and have a humpbacked appearance. The postvertical bristles on the head are well developed and cruciate, with three orbital bristles on each side of the frons. The arista has long plumosity.

Identification Tips

Identification can be made by examining the arrangement of postvertical and orbital bristles, as well as wing structure—specifically, the interruptions in the costa and the fused posterior basal wing cell and discoidal wing cell.

Habitat

Most members are found in tropical to subtropical latitudes, particularly in Africa and the Neotropics. They can be located in decaying organic materials or habitats like burrows of warthogs and ant bears.

Distribution

Widespread globally with 1 species recorded from the Palaearctic, 1 from Nearctic, 1 from Australasian/Oceanian, and many species from the Afrotropical region.

Diet

The immature stages are scavengers, typically found within egg pods of locusts or in human waste. Other species have been observed in decomposing organic matter.

Life Cycle

The life cycle involves scavenging for food during immature stages, with some species residing within specific organic environments until reaching adulthood.

Reproduction

Details about specific reproductive behaviors are not well-documented. However, they likely involve laying eggs on or near scavenged organic matter.

Ecosystem Role

As scavengers, they potentially play a role in the decomposition of organic matter and nutrient cycling within their ecosystems.

Collecting Methods

Netting adults from foliage or organic matter
Collecting immature stages from burrows or organic deposits

Preservation Methods

Ethyl alcohol preservation
Pinned specimens for adults

Evolution

The family Curtonotidae has been historically placed in different families such as Drosophilidae, Diastatidae, and Ephydridae, with its current classification widely accepted after Duda's proposal in 1934.

Misconceptions

None specifically noted, but they are sometimes confused with other small dipterans due to their size and coloration.
