Hesperorhipis albofasciata
Hesperorhipis albofasciata is a species of metallic wood-boring beetle in the family Buprestidae, tribe Xenorhipidini. It is one of four species in the genus Hesperorhipis, which is restricted to Arizona and California. The species exhibits pronounced sexual dimorphism in antennal structure and elytral abbreviation, with males possessing highly modified flabellate antennae and more abbreviated elytra than females. It has been reared exclusively from walnut (Juglans sp.).
Phymatodes decussatus
Phymatodes decussatus is a species of longhorn beetle (Cerambycidae) originally described by LeConte in 1857. The species has undergone significant nomenclatural revision: the name P. decussatus was historically misapplied to a common oak-associated species now correctly called P. obliquus, while the true P. decussatus was previously known as P. juglandis. The species is associated with walnut (Juglans) rather than oak. A single subspecies, P. decussatus posticus, occurs in western North America and Mexico.
