Ant-lions: adult (flying) and carnivorous larva (jaws emerging from sand-pit). Antlions are a family of insects, classified as Myrmeleontidae, from the Greek "myrmex", meaning "ant", and "leon", meaning "lion". Antlions are small, fully developed larvae being 1.5 cm, and adults being 4 cm. Antlions are omnivorous. The antlion larvae eat ants and other insects, while the adult antlion eats pollen and nectar. The antlion is most often called a "doodlebug". 固opFoto / Fortean
