Larval northern dune tiger beetles can pick small enemies up one at a time and execute them. They remain hidden in the ground and only expose themselves for 10 seconds to attack when a single viable targets is within vision radius.
Small and large beetles attack by biting. They can stun enemies.
Large beetles can carve enemies and damage them over time. This ability hits 3 times.
Antlions were originally planned as challenge mode enemies for wood ant missions. They were rejected because their burrows were difficult to implement using hexagonal grid.
