thorny lacewings
Symphrasinae is a subfamily of thorny lacewings within Rhachiberothidae (Neuroptera), recently transferred from Mantispidae. It comprises three genera—Anchieta, Plega, and Trichoscelia—with 60 described species distributed exclusively in the New World from the southwestern United States to southern Argentina. Members possess raptorial forelegs for prey capture. The genus Plega has been documented as an ectoparasitoid of sawfly larvae and pupae.
