What a gorgeous bug. Extremely photogenic! I've found a nice article on them from Utah state,

In Europe it cites a few predators. They are actually from Europe and therefore have no common enemy in the USA... but no matter where you're from there's not much you can do beside drown them lol! If you lived in the US I'd say to document what they eat... I've never seen em here in Texas personally. They almost look like ladybugs. Dyou know why they're called 'Firebugs' ?
