Al Guhl on August 12, 2014 at 9:07 am Reply Thank you for doing such a fine photographic effort of this butterfly. They’ve been heading north through Tucson AZ over the last few weeks and I’ve gotten only one (possibly two) good pix, but have yet to see a male. I swear that the Sennae Sulphurs have been so numerous that just about any time I have a look out of my living room window I see one or two! That cannot be said of many other butterflies here. Thank you again for your skillful captures and then sharing them!
