Kenshi Wiki

Primarily found in The Swamp, Blood Spiders hunt down and suck the nutrition of live prey. They deal approximately 70 damage per hit of equal amount blunt and cut.

They attack in groups and are more dangerous than, say, an average group of dust bandits. Blood Spiders are highly resistant to bleeding damage and recover consciousness quickly. They will try to eat an unconscious or dying character by draining their hunger.

There is also a rarer, and stronger, variant known as the Elder Blood Spider.
