Yeah, this is true. Interestingly, birds, reptiles, and most fish can also see in UV. They have 2 photoreceptors in their eyes that we have, 1 similar to us, and a UV photoreceptor that we do not have.
Our early mammalian ancestors lost 2 of their photoreceptors green (I believe) and UV since they were mostly nocturnal and those colors are useless/not present at night. As many mammals became diurnal, there was a duplication of one photoreceptor and subsequent mutation made it close to the green one we lost. We never got our UV back though, sadly. As a result, most vertebrates other than mammals can see in colors we can't even comprehend.

Ultraviolet light. Bee's can see as though it is daylight approximately two hours after the sun has gone down.
