Thanks a lot for those directions Martin! I went to
the (right) place this afternoon and was duly impressed by the gathering of
Imperial Hairstreaks. Quite a sight! The relationship between the ants and pupae
is also very interesting.
Most of the butterflies, however, seemed intent on
mating. At one point, one hairstreak emerged from its pupate stage and was
immediately seized upon by a waiting male. The two were mating before the
female's wings had even opened up!
Attached is one of the shots I managed to grab
during the hour or so I had there.
