Laelius is a genus of hymenopteranparasitoids in the family Bethylidae. Laelius species are ectoparasitoids of immature stages of beetles, such as Dermestidae, and thus are commonly taken indoors. There are 57 extent species worldwide and 4 additional species known from fossil records in amber.[1][2] A number of species have recently been moved from the genus Rhabdepyris to Laelius.[3]
