How Would You Describe a Ant Lion?

An insect known for its aggressive capture of prey during its larval stage is the ant lion. The larva digs a funnel-shaped sandy pit by using its oval, bristled abdomen, then buries itself in the pit with only its powerful jaws uncovered. Any small insect that ventures over the pit’s edge slips to the bottom and is seized by the ant lion, which sucks the contents of its victim and throws out the empty skin. The adult ant lion does not feed. The best known of the 65 described species occurs in North America and Europe.
