Butterflies

When I was out in Carlos Avery on Thursday there were quite a few butterflies and moths flying around. I know absolutely nothing about these creatures, and I think I'm going to need a new field guide. :) Anyway, from what I can tell based upon an Internet search and a little help from the Minnesota Zoo Butterfly ID chart, this is a Great Spangled Fritillary. (If this is the wrong ID, please let me know.)
