| − | Species in the nine families of this small (~600 species) order of [[insect|insects]] are [[parasite]]s in other insects; their hosts include [[bee]]s, [[wasp]]s, leafhoppers, [[silverfish]], and [[cockroach]]es.

| − | Male '''Strepsiptera''' have wings, legs, eyes, and antennae, and look like flies, though they generally have no useful mouthparts. Females, in all families except the Mengenillidae, never leave their host and are [[neoteny|neotenic]] in form, lacking wings and legs. Males have a very short adult lifetime (usually less than five hours) and do not feed as adults. They search for and mate with a female (whose anterior region extrudes through the host's body). Sperm passes through an opening in the head of the female and from there directly into the body cavity (Haemocoel).

| − | Male Strepsipteran eyes are unlike those of any other [[insect]], resembling the schizochroal eyes found in the [[trilobite]] group known as [[Phacopida]]. Instead of [[compound eye]]s consisting of hundreds of [[ommatidia]], each of which sees one pixel, the strepsipteran eyes consist of a few dozen lenses, each with its own individual [[retina]].

| | + | The '''Strepsiptera''' (known in older literature as ''twisted-winged parasites'') are an order of parasitic insects with nine families making up about 600 species. Their hosts include bees, wasps, leafhoppers, silverfish, and cockroaches. |
| | | | |
| − | The order, named by Kirby in 1813, is named for the hind wings (twisted wing), which are held at a twisted angle when at rest. The forewings are reduced to [[halteres]].

| − | | + | Male Strepsiptera have wings, legs, eyes, and antennae, and look like flies, though they generally have no useful mouthparts. Females, in all families except the Mengenillidae, never leave their host and lack wings and legs. Males have a very short adult lifetime (usually less than five hours) and do not feed as adults. Many of their mouth parts are modified into sensory structures. |
| − | Strepsiptera present an enigma to taxonomists. Some believe they are the sister group to the beetle families [[Meloidae]] and [[Rhipiphoridae]], which have similar parasitic development and forewing reduction; some say they are the sister group to the [[beetle]]s; some say they are the sister group to the [[flies]], which have hindwing halteres.
