Habronattus dossenus
A small jumping spider in the genus Habronattus, native to Mexico and the southwestern United States. Males are renowned for producing complex multimodal courtship displays combining visual signals with seismic (vibratory) signals generated by dorsoventral abdominal vibrations against the substrate. Signal efficacy varies dramatically by substrate type, with leaf litter providing the most favorable transmission environment compared to rocks or sand.
