Strepsiptera

an order of insects containing very small parasitic individuals. The larvae parasitize bees and plant bugs; the females are wingless endoparasites, the males winged (hind wings only). Parasitized insects are said to be stylopised (after Stylops, one of the parasitizing genera) and cause the host sex organs to degenerate.

Understanding how Strepsiptera parasitoids outwit host defenses is particularly exciting, she says, because the order's 500-plus species manage to prey on insects in 34 families.

Several recent molecular phylogenetic studies that focused on Holometabola or other higherlevel groups of insects indicate that Strepsiptera are closely related to beetles, if not beetles themselves (2) (Misof et al.
Strepsiptera have not been included in any published analyses along with both a comprehensive sample of beetle suborders and an extensive sample of beetle families.
Consequently, future studies that (1) obtain data from multiple molecular markers for a broad cross-section of beetles, neuropterids and Strepsiptera, (2) incorporate the latest information from the beetle fossil record, and (3) use appropriate and statistically rigorous methods for estimating beetle phylogeny and divergence times will undoubtedly contribute further and more robust insights into beetle phylogeny and macroevolution, including factors contributing to the apparent success of the order.
