Chloriontinae
Chloriontinae is a subfamily of thread-waisted wasps within the family Sphecidae, established by Fernald in 1905. The group is centered on the genus *Chlorion*, which comprises solitary wasps known for their specialized hunting behaviors. Members of this subfamily are part of the apoid wasp lineage, though they are sometimes classified within broader sphecid or crabronid groupings depending on taxonomic treatment. The subfamily is relatively small and morphologically cohesive.
Podium luctuosum
Podium luctuosum is a species of thread-waisted wasp in the family Sphecidae, first described by Frederick Smith in 1856. It has been documented provisioning its nests with Parcoblatta cockroaches as prey for its developing larvae. The species occurs in Middle and North America, with 614 observations recorded on iNaturalist. Like other members of its genus, it exhibits the characteristic elongated petiole (thread-waisted morphology) typical of sphecid wasps.
