Guides
Trypoxylon carinatum
Trypoxylon carinatum is a species of solitary spider-hunting wasp in the family Crabronidae. As a member of the subgenus Trypargilum, it is among the larger species in the genus. Like other Trypoxylon, females nest in pre-existing cavities and provision cells with paralyzed spiders for their offspring. The species is distributed across North America and Middle America.
Trypoxylon clavatum clavatum
Trypoxylon clavatum clavatum is a subspecies of spider-hunting wasp in the family Crabronidae. It belongs to the subgenus Trypargilum, characterized by medium to large body size within the genus. The wasp nests in pre-existing cavities such as hollow twigs, beetle borings, and abandoned mud dauber nests, provisioning cells with paralyzed spiders for its larvae. Males actively participate in nest guarding and maintenance, a behavior termed 'patriarchate' by naturalist Phil Rau.
Trypoxylon clavatum johannis
Trypoxylon clavatum johannis is a subspecies of spider-hunting wasp in the family Crabronidae. It belongs to the subgenus Trypargilum, which comprises medium-sized to large species within the genus. Like other members of Trypoxylon, this wasp nests in pre-existing cavities and provisions its cells with paralyzed spiders. The subspecies was described by Richards in 1934 and is distributed in North America, with records from Ontario, Canada.
Trypoxylon tridentatum
Trypoxylon tridentatum is a spider-hunting wasp in the family Crabronidae, subgenus Trypargilum. It inhabits mesic and xeric habitats in arid regions, particularly the Baja California peninsula. The wasp provisions nest cells with paralyzed spiders as food for its larvae, showing strong preference for orb-weaving spiders in the family Araneidae. Unlike its congener T. politum, which constructs free-standing mud nests, T. tridentatum nests in pre-existing cavities such as hollow twigs, beetle borings, and abandoned mud dauber nests.
Trypoxylon tridentatum archboldi
Trypoxylon tridentatum archboldi is a subspecies of spider-hunting wasp in the family Crabronidae. As a member of the subgenus Trypargilum, it belongs to a group of medium-sized to large Trypoxylon species that nest in pre-existing cavities rather than constructing free-standing mud nests. The species was described by Krombein in 1959 and is known from North America, with records from British Columbia, Canada. Like other Trypargilum species, it likely exhibits cooperative nesting behavior with males participating in nest guarding and maintenance, though specific behavioral documentation for this subspecies is limited.
