Cicindela tranquebarica tranquebarica
Oblique-lined Tiger Beetle, Oblique-lined Tiger Beetle (nominate subspecies)
Cicindela tranquebarica tranquebarica is the nominate subspecies of the oblique-lined tiger beetle, found across eastern North America. Adults are active in spring and fall, with a life cycle requiring at least one year. The species shows notable habitat flexibility, occurring on dry sandy soils, clay substrates, and saline environments. Adults are generalist predators with large eyes and fast running ability, though they must stop periodically to refocus visually when pursuing prey. The subspecies is distinguished from western populations (C. t. kirbyi) by narrower white elytral maculations.
Erythrodiplax
Dragonlets
Erythrodiplax is a large Neotropical genus of small to medium-sized dragonflies in the family Libellulidae, commonly known as dragonlets. The genus contains numerous species distributed across the Americas, with some members exhibiting unique ecological adaptations. Erythrodiplax berenice, the Seaside Dragonlet, is the only odonate known to develop in saline water, tolerating salinities up to 48%. Species within this genus display diverse reproductive behaviors, with males exhibiting territorial or satellite strategies and engaging in mate guarding during oviposition.
Ochthebiinae
minute moss beetles
Ochthebiinae is a subfamily of minute moss beetles (family Hydraenidae) comprising approximately 14 genera and over 650 described species. It represents the second most species-rich subfamily within Hydraenidae and exhibits exceptional ecological diversity, including terrestrial species and those inhabiting nearly all aquatic environments from freshwater to hypersaline waters. The subfamily contains two tribes: Ochtheosini (four species in three genera) and the much larger Ochthebiini. Molecular phylogenetic studies have revised the classification of Ochthebiini, recognizing six genera and establishing multiple subgenera within the diverse genus Ochthebius.
