How do doodlebugs move?

Doodlebugs, also known as antlions, don't actually "move" in the traditional sense. They are the larval stage of antlion insects, and their primary mode of "movement" is by creating a pitfall trap. Here's how it works:

1. Digging the Pit: The antlion larva uses its strong jaws to dig a conical pit in loose, sandy soil. This pit usually slopes downwards, making it difficult for prey to climb out.

2. Waiting for Prey: The larva then buries itself at the bottom of the pit, leaving only its powerful jaws exposed.

3. Catching Prey: When an ant or other small insect falls into the pit, the antlion uses its powerful jaws to quickly grab it and drag it beneath the sand.

4. Feeding: The antlion then injects digestive enzymes into its prey, liquefying its insides and sucking out the nutrients.

Therefore, the antlion larva's "movement" is more about creating a trap than about moving its body. The larva itself remains relatively still at the bottom of the pit, waiting for its prey to fall in.
