Leucospis
Leucospis is a genus of large chalcidoid wasps in the family Leucospidae. Adults are typically 2–14 mm long with distinctive yellow and black coloration that resembles mason wasps. Females possess a uniquely curved ovipositor that arches over the back, used to drill into wood and reach host larvae in sealed cells. Larvae develop as ectoparasites on solitary bees and wasps, with typically only one parasite emerging per host cell. The genus has a global distribution in tropical and temperate regions.
Leucospis affinis floridana
Leucospis affinis floridana is a subspecies of chalcidoid wasp in the family Leucospidae. As a member of this family, it is notably large compared to typical chalcid wasps and possesses distinctive morphological adaptations for parasitism. The species is a parasitoid of solitary bees, particularly megachilid bees including mason bees and leafcutter bees. Females use a specialized ovipositor that curves over the abdomen to drill through wood and deposit eggs in host nests.
