Sassacus
Leaf-beetle Jumping Spiders
Sassacus is a genus of jumping spiders (Salticidae) first described in 1895. Adults are exceptionally small, measuring 3-5 mm (males) or 4.4-5.5 mm (females). Many species exhibit iridescent coloration and compact bodies, suspected to mimic chemically defended leaf beetles (Chrysomelidae). The genus occurs across North America from southern British Columbia through Central America, inhabiting broadleaved plants in open fields and forest edges.
