Ambloplisus ornatus
Ambloplisus ornatus is a species of ichneumon wasp in the family Ichneumonidae, first described by Cresson in 1868. It is a parasitoid wasp belonging to the superfamily Ichneumonoidea, one of the most species-rich groups of parasitic wasps. The genus Ambloplisus is part of the diverse ichneumonid fauna of North America.
Exochus albifrons
Exochus albifrons is a species of ichneumon wasp described by Cresson in 1868. It belongs to the genus Exochus within the family Ichneumonidae, a large family of parasitoid wasps. The species has been documented from multiple locations in California and Alberta, Canada. Like other members of its genus, it is presumed to be a parasitoid, though specific host records for this species are not readily available in the provided sources.
Hoplisoides tricolor
sand wasp
Hoplisoides tricolor is a species of solitary sand wasp in the family Crabronidae, originally described by Cresson in 1868. It is one of approximately eighteen Hoplisoides species found in North America north of Mexico. Like congeners, it is a ground-nesting wasp that hunts treehoppers (Membracidae) as prey for its larvae. The species occurs across Central America and North America, with most Hoplisoides species concentrated in western North America.
Zagryphus nasutus
Zagryphus nasutus is a species of ichneumon wasp in the family Ichneumonidae, subfamily Ichneumoninae. First described by Cresson in 1868, this species belongs to a genus characterized by distinctive morphological features of the clypeus. The genus Zagryphus was established by Heinrich in 1962 with Z. nasutus as the type species. Like other ichneumon wasps, it is presumed to be parasitoid, though specific host relationships remain undocumented. The species has been recorded in the southwestern United States, particularly in Arizona.
