This specimen of lepidoptera appeared on my patio today, and I think it will be around for awhile. It seems to have a much sturdier wing than one customarily sees on these insects so it should withstand wind and rain and any predatory birds flying by. I'm glad it's decided to make a permanent home in my garden. I think it will be a good addition to the neighborhood.
This is the best type of insect to live on your plants! Lovely. I do not understand the fibonacci sequence even though I looked it up after i read your comment. I can tell it is a pattern and seems to naturally occur in nature. Math was not my strong suit. ;-( I am sure others will be researching it as well. ;-)
On a serious not we have a butterfly bush in our garden (Buddleja) and I am looking forward to when it flowers so I can get some real butterflies :)
(and RE: black squirrels, I did get a good shot of one this pat winter: http://365project.org/cglist/365/2010-12-26)
