Hi Rodney

I'm not an expert on butterfly behaviour so if I get this wrong I'm
sure I will be corrected but as nobody's replied I thought I'd have my
tup'pence worth.

>From what I've seen butterflies are indeed territorial, most commonly
flying at other butterflies but indeed seems to chase almost anything
that moves. I would assume that its a breeding strategy whereby its
chasing off other males (assuming its a male) so that it increases the
chances of it breeding with more females in its domain.
