the wings both flap they could be the same color they both make the animal fly.
Actually, no animal has scales which can fly, other than perhaps the flying fish. Bats have skin, birds have feathers. Insects would not be considered to have scales either. Pterosaurs flew and may have had scales, but they are now extinct.
Hippos cannot fly, they are mammals and mammals can't fly, however their is an exception of the bat being a flying mammal.
They don't. Wombats are terrestrial-dwelling marsupials. They are not members of the bat family.
A bat fly is any of the family Nycteribiidae of flattened, spider-like parasitic flies, which do not have eyes or wings.
there are millions of flying bugs that suck yr blood............*
