The orange sulphur (sometimes
misspelled as sulfur) butterfly had a banner year in 2002. These
butterflies, along with their nearly identical cousins, the clouded
sulphurs, were everywhere by the thousands. 2003, 2004, and now 2005
do not look to be good for these beautiful creatures. It's now July
first and I've only seen a very few. (Footnote, June 2007 - the
orange sulphurs have never reappeared in anywhere near the numbers
of 2002). |
