Suu

From the Super Mario Wiki

Suu are spider enemies of the Easton Kingdom found in the game Super Mario Land. They attack by trying to drop on Mario from the ceiling. To defeat these arachnids the plumber had avoid getting hit on the Suu's descent, then jump or shoot two superballs at the spider to earn 400 points. Suus only appear in World 3-2 of the Easton Kingdom. A similar enemy named Scuttle Bugs appear to share a yellow-black pattern on their abdomens. This may imply that Suus are related to Scuttle Bugs.
