Although they prey on cicadas, cicada-killer wasps are themselves preyed upon by a group of wasps called velvet ants. The female velvet ant sneaks into the cicada-killer’s tunnel and lays an egg in a nest cell. The cicada-killer larva eats its cicada and grows; when it pupates, the velvet ant larva eats the pupa.
