Trapinch is an orange, insectoid Pokémon. It has a round body with a white underside and four stumpy legs. It also has a proportionally large head, small black eyes with twinkle-shaped pupils, and a zigzagging mouth.
Trapinch's large jaws are powerful enough to crush boulders. It lives in arid deserts, and it can go a week without water. Instead of actively hunting prey, it digs into the sand to build its bowl- or cone-shaped nests, where it waits for prey to stumble inside and become trapped. The weight of this Pokémon's large head makes Trapinch move slower but becomes vulnerable after falling or rolling into their backs. Its natural predator is Sandile.
Trapinch's base Attack stat is higher than that of its evolved form and is the same as that of its final evolved form. That may be a reference to the fact that antlion larvae are more aggressive and predatory than their adult stages.
It also has the highest base Attack stat of all Pokémon that can evolve twice.
Because of this, evolving a Trapinch in Pokémon GO will result in its CP going down, a trait otherwise only seen in cocoon Pokémon such as Kakuna.
