Adults measure 15–25 mm in length and are characterized by reddish-brown coloration with four narrow dark abdominal bands and distinctive violet-blue wings. Females hunt and paralyze large wandering spiders, particularly wolf spiders (Lycosidae), to provision underground nests for their larvae. Males exhibit perching behavior on elevated structures and compete for access to females. The species includes nine recognized subspecies with variable geographic distributions.

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.

Xerochares expulsus is a species of spider wasp in the family Pompilidae, described by Schulz in 1906. It belongs to the genus Xerochares, which comprises spider wasps adapted to arid and semi-arid environments. The species has been documented in observational databases but remains poorly studied in scientific literature.
Zatypota anomala
Zatypota anomala is a koinobiont ichneumonid wasp in the tribe Ephialtini that parasitizes mesh web weaving spiders in the family Dictynidae. It is strictly specialized on Dictyna and Nigma spiders in Europe, with a distribution concentrated at mid-elevations in central European forest ecotones. The species exhibits elevation-dependent host partitioning, parasitizing Nigma at lower elevations (179–254 m a.s.l.) and Dictyna at higher elevations (361–870 m a.s.l.). First recorded from Italy in 2022, parasitizing Dictyna pusilla.
