Diplotaxis bidentata is a species of scarab beetle in the family Scarabaeidae. It is found in North America. The species is a small chafer that has been observed congregating on low vegetation, apparently to detect pheromone trails in search of mates.
Oxidus
greenhouse millipedes
Oxidus is a genus of flat-backed millipedes in the family Paradoxosomatidae, containing approximately nine described species, though recent revision recognizes five valid species with one species inquirenda. The genus is characterized by a cosmopolitan member, Oxidus gracilis (the greenhouse millipede), which has achieved global distribution in temperate and sub-tropical regions, while other species exhibit restricted endemic ranges. Phylogenetic analysis based on mitochondrial COI and 16S rRNA genes confirms Oxidus as monophyletic and closely related to the genus Tylopus. Species within the genus are distinguished primarily by gonopod morphology, coloration, and body size.
