Arachnode

The Arachnode is an awrapnid that, resembles a cocoon while dormant on its web but reveals its true form once a Pikmin or leader gets caught in the web; it uncurls its legs and wanders up to its prey, consuming them quickly once it has reached them. It may also wander around the web freely in order to avoid Pikmin that are being thrown at it.

In Pikmin: Decayed Leaf
Arachnodes  are a returning enemy in Pikmin: Decayed Leaf. The spider tends to stay in its web; which is usually in the path that Winged Pikmin take. Pikmin caught in the web will be eaten by the spider. However, throwing a fire starter will burn the web and cause the spider to fall down. On the ground, it will attempt to either run away or eat Pikmin; although it’s much more weaker. The Arachnode can also be knocked out of its nest by a Rock Pikmin.
