Rabid Wolf (Rabidosa rabida)

The Rabid Wolf is a species of yellow spiders that are found in limited regions in North America. They are often confused for rabies-carriers because of their name; however, the term ‘rabid’ refers to their fast-moving and erratic movements marked by excessive enthusiasm.

Eggs

The egg sacs are between 7 and 10 mm in diameter.The female of the species drags their egg mass around along with them. The mass is attached to their bodies by a silken cocoon spun around it. As the time for the eggs to hatch nears, the cocoon gradually turns darker – from glossy white to a muddy brown.

They are not considered poisonous according to government and academic sources. They are also not aggressive and usually run away if they feel threatened, or in danger.
