Spiders of the genus Lutica are fossorial inhabitants of coastal dunes of southern California, Baja California and the California Channel Islands. They live in silk-lined burrows concentrated beneath dune vegetation. Lutica are sit-and-wait predators that subdue insects that walk near or over burrows . They are sedentary and do not engage in aerial dispersal via ballooning . Adult males abandon their burrows during the late summer and early fall to wander in search of females . Females produce eggsacs and guard them till they die; spiderlings emerge in the spring. Dune trapdoor spiders (Aptostichus simus) prey on Lutica, while the larvae of a therevid fly are external parasites.
