Editing Strepsiptera (section)

==== Males ====
Males of the Strepsiptera have [[insect wing|wings]], [[arthropod leg|legs]], [[compound eye|eye]]s, and [[antenna (biology)|antennae]], though their [[Arthropod mouthparts|mouthparts]] cannot be used for feeding. Many have mouthparts modified into sensory structures. The males bear a superficial resemblance to flies.<ref name="insencyc" /> The forewings are modified into small club-shaped structures called [[halteres]], which sense [[gyroscopic]] information.<ref>{{Cite journal |last1=Pix |first1=W. |last2=Nalbach |first2=G. |last3=Zeil |first3=J. |date=August 1993 |title=Strepsipteran forewings are haltere-like organs of equilibrium |url=http://link.springer.com/10.1007/BF01138795 |journal=Naturwissenschaften |language=en |volume=80 |issue=8 |pages=371–374 |doi=10.1007/BF01138795 |bibcode=1993NW.....80..371P |s2cid=43790345 |issn=0028-1042}}</ref> A similar organ exists in flies, though in that group the hindwings are modified instead, and the two groups are thought to have independently evolved the structures.<ref>{{Cite journal |last1=Rokas |first1=Antonis |last2=Holland |first2=Peter W.H. |date=November 2000 |title=Rare genomic changes as a tool for phylogenetics |url=https://linkinghub.elsevier.com/retrieve/pii/S0169534700019674 |journal=Trends in Ecology & Evolution |language=en |volume=15 |issue=11 |pages=454–459 |doi=10.1016/S0169-5347(00)01967-4|pmid=11050348 }}</ref> The hindwings are generally fan-shaped, and have strongly reduced [[Insect wing#Venation|venation]].

Adult male Strepsiptera have eyes unlike those of any other [[insect]], resembling the eyes found in the [[trilobite]] group [[Phacopina]]. Instead of a [[compound eye]] consisting of hundreds to thousands of [[ommatidia]], that each produce a [[pixel]] of the entire image, the strepsipteran eyes consist of only a few dozen "eyelets"  that each produce a complete image. These eyelets are separated by cuticle and/or setae, giving the cluster eye as a whole a blackberry-like appearance.<ref name="insencyc" /><ref>{{cite journal |author1=Buschbeck, E. K. |author2=B.
