Diplotaxis brevisetosa
Diplotaxis brevisetosa is a species of scarab beetle in the family Scarabaeidae, tribe Diplotaxini, described by Linell in 1897. It is a small chafer beetle occurring in the Nearctic region, specifically known from Texas. Like other members of its genus, it is attracted to lights at night and has been observed congregating on low vegetation. The specific epithet 'brevisetosa' refers to short setae (bristles), a distinctive morphological feature of this species.
Diplotaxis subangulata
Diplotaxis subangulata is a small scarab beetle in the family Scarabaeidae, subfamily Melolonthinae, described by LeConte in 1856. The genus Diplotaxis comprises small chafers, and this species occurs across western North America from British Columbia to Baja California, with records throughout the southwestern United States. Adults have been observed congregating on low vegetation, apparently to intercept pheromone trails in search of mates. The species is attracted to lights at night.
