Allantus nigritibialis
Allantus nigritibialis is a sawfly species in the family Tenthredinidae, described by Rohwer in 1911. Like other members of the genus Allantus, this species likely has larvae that feed on rose foliage, though specific life history details for this particular species are poorly documented. Adult sawflies are small wasp-like insects with saw-like ovipositors used to insert eggs into plant tissue. The species name 'nigritibialis' refers to dark or black tibiae (leg segments), suggesting a distinguishing color pattern on the legs.
Boethus
Boethus is a genus of parasitoid wasps in the family Ichneumonidae. Species in this genus are known to attack sawfly hosts, with Boethus thoracicus documented as a parasitoid of Arge rosae (rose sawfly). The genus belongs to the superfamily Ichneumonoidea, one of the largest groups of parasitoid wasps.
