Grammar!

[Colin Cracknell]

This may seem an odd place in which to ask a grammatical question, but 
which of the following is (are?) correct?

        1) Diptera is a taxon.
        2) Diptera are a taxon.
        3) "Diptera" is a taxon.

In the first case, a taxon is a set of organisms. In the second case, a 
taxon is the organisms in a set, and n the third case a taxon is the 
*name* of a set of organisms.

All opinions are my own, but Darter Systems agrees with me.
