I've been out looking for them too, but with no luck, yet! Perseverance is the key, I keep telling myself that anyway.
Perhaps we can manage a trip to your part of the world one day Guy, It would be great to put a face to the name, and to travel to a country where there is still some countryside with good numbers of butterfly, and a knowledgeable guide.

and teacher (if you don't do enough of that already!) No pressure though.
Cheers
