Sure. That's taxonomy, as practised by biologists. People who merely go
out and catch insects as a hobby aren't responsible for drawing up the
taxonomy. I suppose they may be able to contribute to it if they catch
something new. But after all, if a collector catches something not in his
bug book, what then? Suppose he invents a name for it, and assigns it a
place in the taxonomy, based on its resemblance or apparent relationship
to something already described. Is this science? Possibly, if his
classification is based on sound biological reasoning. In which case a
stamp collector might be said to be practising science if he did
something similar with a rare stamp. Indeed, a hypothesis about the
origins of a stamp might well be more testable than a hypothesis about
the appropriate classification of a butterfly.

No, science seeks to address the "why", not just the "what". I think this
is what Rutherford meant by "stamp collecting"- that too often people
deceive themselves into thinking they have explained something, when in
fact all they have done is given it a name.
The difference between anatomy and physiology is a good example.
Anatomy names the parts of the body and provides schemes for
classifying them, whereas physiology seeks to explain how they actually
function. Of course in practice the two disciplines necessarily co-exist.
