Ah, an eleven-spot ladybird beetle. They are NOT bugs, despite being commonly called ‘ladybugs’ in North America. Ladybird beetles, tiger beetles, dragonflies, and hellgrammites are, weight-for-weight, the most vicious predators on Earth. Ladybirds prefer aphids, but will go for other prey if aphids aren’t available. Dragonflies and hellgrammites go for flies and mosquitos, mostly. Tiger beetles go for anything which holds still long enough.
