Cicindelinae
tiger beetles
Cicindelinae is a subfamily of predatory beetles commonly known as tiger beetles. Adults are characterized by large eyes, long slender legs, and powerful mandibles adapted for capturing fast-moving prey. They exhibit a distinctive run-stop-run hunting pattern necessitated by their visual processing limitations at high speeds. The subfamily contains approximately 2,822 species in 120 genera distributed worldwide, though they are most diverse in tropical and subtropical regions. Many species show strong habitat specificity, with some restricted to particular sand dune systems, riparian zones, or rock outcrops.
Patrobina
Patrobina is a subtribe of ground beetles (Carabidae) within the tribe Patrobini, established by Kirby in 1837. Members of this subtribe are small to medium-sized beetles associated with moist, often riparian or wetland habitats. The subtribe includes genera such as Patrobus and others, though the precise generic composition has been subject to taxonomic revision. Patrobina beetles are part of the diverse carabid fauna that contributes to predatory control of invertebrate populations in temperate ecosystems.
Pelophilini
Pelophilini is a small tribe of ground beetles (Carabidae) in the subfamily Nebriinae, established by Kavanaugh in 1996. The tribe contains a single genus, Pelophila, with species distributed in cool, moist habitats across the Northern Hemisphere. Members are characterized by adaptations to riparian and shoreline environments.
Taphrocerus sulcifrons
Taphrocerus sulcifrons is a small buprestid beetle described by Fisher in 1922. The species belongs to the genus Taphrocerus, a group of minute metallic beetles often associated with sedges and other herbaceous plants in moist habitats. Based on collection records, this species occurs in both Middle America and North America. Field observations indicate adults are active in spring and early summer, with specimens collected by sweeping vegetation near water sources.
