Antlion

The Antlion is an enemy found in Deserts during the day, and are also found in Underground Deserts. They remain stationary with their head sticking out of the ground, and will shoot stackable sand at players when they enter their line of sight. They can only launch their projectile at an upwards angle (within about 45 degrees to the left and right), so approaching from lower ground means you will usually be out of their line of fire. They can be rather annoying to less experienced Terraria players.

On the, the Albino Antlion variant also appears.

Trivia

 * The Antlion is based on real life larvae, which dig sand pits as traps for other insects. The antlion will throw sand at escaping prey, causing its victims to tumble down into the center of the pit where the hungry antlion is waiting. When the larvae grow up, they resemble the Antlion Swarmer.
 * The NPC ID image contains only the head. The body is stored not by an ID, but rather by its name: "AntlionBody.png"
 * The projectiles the Antlion shoots can damage other enemies, not just the player. This is possible because it is a sand ball, almost, if not exactly the same as the one fired by the Sandgun.
 * "Antlion" is commonly mispronounced as "antillion", when, since it's based on the insect, it can be assumed that one would pronounce it the same as the insect – "ant-lion".
 * This is one of only two or three creatures besides the player that can place blocks in the world. (The other being the Snow Balla, and debatably the Wall of Flesh.)
