Arachnid
Koch's Wolf Spider
Alopecosa kochiAlso known as Koch Wolf Spider
Koch's wolf spiders are active nocturnal hunters that sprint across leaf litter and open soil to ambush ground-dwelling insects rather than weaving webs. Females carry their silken egg sacs attached to their spinnerets and later transport dozens of newly hatched spiderlings on their abdomens. Their dark greyish-brown mottled body pattern provides effective camouflage against fallen leaves, bark, and rocky terrain across North American habitats.

Responsible observation
