Gyascutus caelatus
Gyascutus caelatus is a species of metallic wood-boring beetle in the family Buprestidae. The species is distributed across Central America and North America. Field observations from Arizona indicate adults are active during summer months and are associated with Acacia species, particularly sweet acacia (Acacia rigidula).
Xenorhipis osborni
Xenorhipis osborni is a metallic wood-boring beetle in the family Buprestidae, tribe Xenorhipidini. It is native to west Texas and adjacent regions of North America. The species exhibits pronounced sexual dimorphism in antennae, with males possessing highly modified flabellate antennae bearing numerous olfactory sensillae, presumably for detecting female sex pheromones. Larval development occurs in dead branches of acacia species (Fabaceae), particularly black acacia (Vachellia rigidula) and catclaw acacia (Senegalia greggii).
