What is a wingless insect?
Wingless flies. True flies are insects of the order Diptera. The name is derived from the Greek di- = two, and ptera = wings. Most insects of this order have two wings (not counting the halteres, club-like limbs which are homologous to the second pair of wings found on insects of other orders).
Hexapoda is then divided into two classes: the Entognatha includes primitively wingless hexapods such as springtails, while all the ‘true’ insects are subdivided into five major groups also know as superorders, the Apterygota, Palaeoptera, Polyneoptera, Paraneoptera and Endopterygota.
Sep 26, 2023 · Wingless flies and mosquitoes have evolved to live in different environments, such as underground or in water. Some examples of wingless dipterans include crane flies, which are known for their long legs, and black flies, which are adapted to living in fast-flowing water.
- Order Thysanura. The silverfish and firebrats are found in the order Thysanura. They are wingless insects often found in people's attics, and have a lifespan of several years.
- Order Diplura. Diplurans are the most primitive insect species, with no eyes or wings. They have the unusual ability among insects to regenerate body parts.
- Order Protura. Another very primitive group, the proturans have no eyes, no antennae, and no wings. They are uncommon, with perhaps less than 100 species known.
- Order Collembola. The order Collembola includes the springtails, primitive insects without wings. There are approximately 2,000 species of Collembola worldwide.
- Overview
- Distinguishing taxonomic features
The wings are the most distinctive feature of Diptera; they consist of a pair of functional forewings and reduced hind wings called halteres that serve as balancing organs. Except for male scale insects, only Diptera have hind wings modified into halteres. The thorax consists almost entirely of mesothorax filled with muscles that operate the forewings. This feature is useful in identifying wingless flies. The single pair of wings also distinguishes Diptera from other insects called flies (e.g., caddisflies, dragonflies), while the posterior halteres separate the Diptera from other insects that have one pair of wings (e.g., some mayflies and beetles).
Division into suborders is based on structure of antennae and wing venation. Another major feature is chaetotaxy, the arrangement of strong bristles, many in fixed positions and given individual or group names. Separation of Diptera into families is based on habitats and habits (e.g., feeding) of larvae and adults. Genera and species are distinguished by details of head structure, shape and degree of separation of eyes, profile of head, and shape and proportions of leg segments. Abdominal shape often determines characteristic appearance of a genus, but it is difficult to define; the shape varies as the insect is starved, well fed, or pregnant (viviparous flies, such as tsetse).

The Diptera are familiar to everyone as just 'flies' - such as house flies and blue bottles - and this order of insects also includes daddy long legs, midges and mosquitoes. Most flying insects - the Pterygota - have four wings, and the ancestors of the Diptera had four wings.
Jan 1, 2009 · The Diptera, commonly called true flies or two-winged flies, are a group of familiar insects that includes mosquitoes, black flies, midges, fruit flies, and house flies. The Diptera are among the most diverse insect orders, with approximately 150,000 described species.
