When i first learned of its name, I thought there has been a mistake. The insect in the picture does not do justice to such a ferocious name. It has a slender, beautiful body with delicate wings and big round eyes and does not come across as a ferocious predator. Turns out, I’m right (well, at least partially).
The adult antlion (the one you see in the picture) feeds on nectar and pollen. The “lion” in its name comes more because of it’s larval stage when it traps and hunts many soft bodied insects that wander near its pit.
