Strigoderma knausi
A small scarab beetle endemic to the Great Plains sand dune systems of south-central Kansas, Oklahoma, and northern Texas. Males are frequently encountered by sweeping low vegetation or at light traps, where they adopt a characteristic horizontal posture with forelegs extended and antennal clubs spread to detect female sex pheromones. The species was described from specimens collected by Warren Knaus in 1923–1925 at the type locality near Medora, Kansas, and named in his honor. Females are extraordinarily rare in collections, with only a single specimen among nearly 100 examined by Bader (1992).
