The Arachnode is a Spider-like creature in Pikmin 3. Upon seeing one, they'll take on a cocoon appearance, but once a Pikmin or leader is caught in its web, it will reveal its true form and try to kill them.

They act as hazards for Winged Pikmin. When Winged Pikmin are carrying anything back to the Onion, and a Arachnode and its web are in the way, the Winged Pikmin will get stuck, putting them at risk of being eaten.

Strategy

To defeat it, a Pikmin or leader must be thrown at its web. After being caught in the web, the creature will try to eat the immobilized Pikmin or leader. At this time, throw another Pikmin (preferably Rock Pikmin) directly at it to cause damage. Once defeated, its web will break apart and the creature will be ready to be taken to back to the Onion.
