Agrilus walsinghami
Agrilus walsinghami is a sexually dimorphic jewel beetle (family Buprestidae) found across western North America. It is among the most visually striking species in its genus, with males exhibiting bronzy-brown and brassy coloration while females are uniformly blue to greenish-blue. Adults are active during late summer and early fall, an unusual seasonality for wood-boring beetles in this region. The species is strongly associated with gray rabbitbrush (Ericameria nauseosa), which is presumed to serve as its larval host despite the absence of confirmed rearing records.
Bothrotes plumbeus
Bothrotes plumbeus is a species of darkling beetle in the family Tenebrionidae. Records indicate it has been collected in the southwestern United States, with observations from locations in New Mexico and surrounding regions. The species is associated with arid and semi-arid habitats, including grasslands and open woodlands. Like other tenebrionids, it is likely nocturnal and ground-dwelling, though specific behavioral details remain limited.
Cicindela pimeriana
Cochise Tiger Beetle
Cicindela pimeriana, known as the Cochise tiger beetle, is a species of flashy tiger beetle in the family Cicindelidae. It occurs in North America, with records from the southwestern United States and Mexico. The species is associated with open, sandy habitats including playa edges. Observations suggest late-season activity, with adults encountered in September.
Cicindelidia tenuisignata
Thin-lined Tiger Beetle
A tiger beetle species in the genus Cicindelidia, found in alkaline wetland margins and lake shores in the southwestern United States. Adults are active during late summer and fall, with records from September in New Mexico. The species is less commonly encountered than related alkali-adapted tiger beetles and is attracted to ultraviolet light at night.
Gyascutus planicosta obliteratus
Gyascutus planicosta obliteratus is a subspecies of metallic wood-boring beetle (family Buprestidae) found in the southwestern United States. The species is associated with saltbush habitats, particularly Atriplex canescens (four-winged saltbush), on which adults have been observed perching. The subspecies represents one of several regional forms within the Gyascutus planicosta complex. Field observations from southeastern New Mexico indicate late-season adult activity in September.
Paradejeania rutilioides nigrescens
Spiny Tachinid Fly, Hedgehog Fly
Paradejeania rutilioides nigrescens is a subspecies of the spiny tachinid fly, a large, robust parasitoid fly in the family Tachinidae. It is distinguished from the nominate subspecies by darker coloration. The species is known from western North America, where adults are active in late summer and fall, commonly visiting flowers of rabbitbrush and other late-season blooms. Like other tachinids, it parasitizes caterpillars, with documented hosts including tiger moths in the family Erebidae.
