Derobrachus hovorei
Palo Verde Root Borer, Palo Verde Beetle, Palo Verde Borer Beetle
Derobrachus hovorei is a large longhorn beetle native to the southwestern United States and northern Mexico. It was formally described as a distinct species by Santos-Silva in 2007, having been previously confused with D. geminatus for over a century. Adults are among the largest beetles in North America, reaching up to 3.5 inches in length. The species is named for its larval association with palo verde trees (Parkinsonia spp.), though it has been observed feeding on roots of various other tree species in urban environments.
Faculta
Palo Verde Webworm (F. inaequalis)
Faculta is a genus of small moths in the family Gelechiidae, established by Busck in 1939. The genus contains three described species: F. inaequalis, F. synthetica, and F. triangulella. F. inaequalis, commonly known as the Palo Verde Webworm, is the best-known species due to its conspicuous larval behavior of spinning silken tubes on host trees. The genus is restricted to arid regions of the southwestern United States and adjacent Mexico.
Faculta inaequalis
Palo Verde webworm
Faculta inaequalis is a small gelechiid moth commonly known as the Palo Verde webworm. The species is endemic to the southwestern United States and northwestern Mexico, where its larvae construct conspicuous silken tubes on Palo Verde trees. Despite being abundant and easily observed, many aspects of its biology remain poorly documented. The moth poses no significant economic threat to its host plants.
Stenosphenus sobrius
Stenosphenus sobrius is a species of longhorned beetle in the family Cerambycidae, described by Newman in 1840. Adults have been observed on fresh wind-thrown branches of palo verde (Cercidium floridum) in the San Lucan xeric scrub of Baja California Sur, Mexico. The species appears to be associated with woody legume hosts and has a distribution spanning Middle America and North America.
