As a member of the genus Eleodes, it shares the characteristic defensive head-standing behavior common to clown beetles. The species is found in arid regions of western North America. Like other Eleodes species, it possesses chemical defense glands that produce noxious secretions when disturbed.
Eleodes nigrina
desert stink beetle
Eleodes nigrina is a species of darkling beetle in the family Tenebrionidae, commonly referred to as a desert stink beetle. It belongs to the genus Eleodes, a group known for defensive head-stand posturing when disturbed. The species was described by LeConte in 1858. Available information on this species is limited, with few detailed ecological or behavioral studies published.
Embaphion contusum
Embaphion contusum is a species of darkling beetle in the family Tenebrionidae. The species was described by LeConte in 1858 and contains three recognized subspecies: E. c. contusum (the nominate subspecies), E. c. laminatum (Casey, 1890), and E. c. grande (Blaisdell, 1909). Like other members of the genus Embaphion, this species exhibits the explanate (flattened and expanded) body form characteristic of the group. The genus Embaphion is part of the diverse darkling beetle fauna of western North America.
Eupompha fissiceps
Cleft-headed Blister Beetle
Eupompha fissiceps is a blister beetle in the family Meloidae, commonly known as the cleft-headed blister beetle. The species occurs in arid regions of southwestern North America and Central America. Adults have been observed feeding on creosote bush (Larrea tridentata) flowers, often in mating aggregations. The specific epithet 'fissiceps' refers to a characteristic division or cleft in the head structure.
Gyascutus planicosta
Gyascutus planicosta is a large metallic wood-boring beetle in the family Buprestidae. Adults reach up to 50 mm in length and display brilliant metallic coloration. The species occurs in the desert southwest of North America, with larvae developing in living roots of host plants rather than dead wood. Three subspecies are recognized, with G. p. obliteratus occurring in western Texas and southern New Mexico.
Harpalus gravis
Harpalus gravis is a species of ground beetle in the subfamily Harpalinae, described by John Lawrence LeConte in 1858. It belongs to the large and diverse genus Harpalus, which contains numerous ground beetle species found across North America. Like other members of this genus, H. gravis is likely a nocturnal or crepuscular predator that forages on the ground surface. The specific epithet 'gravis' (Latin for 'heavy' or 'serious') may allude to some aspect of its physical characteristics or behavior.
