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.

The linear regression of this relationship gives the following model for one strepsipteran developing in a host: Strepsipteran head width = 0.
When three strepsipterans develop in the same host, their size appears to be reduced from what would be expected when only a single strepsipteran utilizes a host.
Size has often been used in distinguishing strepsipteran species (Kifune & Hirashima 1980).
invicta, but the range of this ant now includes South Carolina (USDA-ARS 2007), and fire ant mounds are abundant in the area where the strepsipteran was collected.
