Dielis
scoliid wasps
Dielis is a New World genus of scoliid wasps (Hymenoptera: Scoliidae) in the tribe Campsomerini, formerly treated as a subgenus of Campsomeris. The genus comprises 12 species of medium to large solitary aculeate wasps distributed from Canada to southern South America. Adults are nectar-feeders, while larvae develop as ectoparasitoids of scarab beetle grubs in soil. The genus is notable for pronounced sexual dimorphism in color pattern and body structure, and for unusual mitochondrial genome architecture including a split cox2 gene.
