It inhabits moist forest environments and has been documented from multiple counties in Oregon and California.
Euagridae
Spiny Curtain-web Spiders
Euagridae is a family of mygalomorph spiders commonly known as Spiny Curtain-web Spiders. The group was established as a tribe by Robert Raven in 1979, elevated to subfamily rank in 1985, and recognized as a full family by Opatova et al. in 2020 based on molecular phylogenetic analyses. As of 2025, the family comprises fourteen genera. Members are distinguished by their spiny morphology and curtain-web construction behavior.
Knulliana
banded hickory borer
Knulliana is a monotypic genus of longhorn beetles (family Cerambycidae) containing the single species Knulliana cincta, commonly known as the banded hickory borer. The genus was established by Linsley in 1962 and is classified within the tribe Bothriospilini. The sole species ranges across the eastern half of North America from Canada to the Bahamas and Mexico, with one subspecies extending into the Sonoran Desert. Adults are associated with hickory and oak trees, where larvae develop as wood-borers.
Neobarrettia
arid-land katydid, spiny predatory katydid
Neobarrettia is a genus of nine North American predatory katydids distinguished by prominent spines and powerful mandibles adapted for carnivory. These insects inhabit arid and semi-arid regions from the southwestern United States through Mexico. They are known for aggressive threat displays and the ability to inflict painful bites when handled.
Patapius spinosus
