The vast majority of living strepispterans are placed within the grouping Stylopidia, which includes the families [[Corioxenidae]], [[Halictophagidae]], [[Callipharixenidae]], [[Bohartillidae]], [[Elenchidae]], [[Myrmecolacidae]], [[Stylopidae]], [[Protelencholacidae]] (extinct) and [[Xenidae]].<ref name=":0" /> All Stylopidia have endoparasitic females that have multiple genital openings.<ref name="insencyc" /> Two living families, [[Mengenillidae]] and [[Bahiaxenidae]], are placed outside of this group, along with several extinct families.<ref name=":0" />

The Stylopidae have four-segmented tarsi and four- to six-segmented antennae, with the third segment having a lateral process. The family Stylopidae may be [[paraphyletic]].<ref name="insencyc" /> The Elenchidae have two-segmented tarsi and four-segmented antennae, with the third segment having a lateral process. The Halictophagidae have three-segmented tarsi and seven-segmented antennae, with lateral processes from the third and fourth segments.<ref name="borror" />
The Stylopidae mostly parasitize wasps and bees, the Elenchidae are known to parasitize [[Fulgoroidea]], whereas the Halictophagidae are found on leafhoppers, treehoppers, and mole cricket hosts.<ref name="borror" />

Strepsipteran insects in the genus [[Xenos (insect)|''Xenos'']] parasitize ''[[Polistes carnifex]]'', a species of social wasps.<ref name="Kathirithamby">{{cite journal | last1 = Kathirithamby | first1 = Jeyaraney | last2 = Hughes | first2 = David | year = 2006 | title = Description and biological notes of the first species of Xenos (Strepsiptera: Stylopidae) parasitic in Polistes carnifex F.

Here they remain until they thrust through the cuticle and pupate (males) or release infective first-[[instar]] larvae onto flowers (females). These larvae are transported back to their nests by foraging wasps.<ref name="Hughes other">{{cite journal |author1=Hughes, D.
