Mosquito hawk? Yeah, that's quite spot on, I'd say. Hog less so though, imo. They, however, eat quite a range of insects though.
Their flying ability is awesome. Impressive. Some peopsies are afraid of them.. but that's not necessary. They do not sting and might only bite when someone tried to catch them by hand, maybe.
In prehistoric days, they lived alongside the dinosaurs/that time, these insects grew really big. Almost the exact same shape they had but quite a bit bigger.
Ah.. Sir D. Attenborough on the subject..
I know you believe in a god.. soit/I respect you.. but I hope you don't deny praehistory a/o the 'actual' age this planet has, QV.
