I can't shoot a single photo of a flower these days without bees, butterflies, late hummingbirds, and even birds, competing with me for their attention. It's really incredible how Nature knows the seasons are changing and they change their innate behaviors without thought. I've noticed that each insect stays a bit longer at each flower. They aren't so anxious to use any energy to find their glorious nectar. In spring and summer, these same insects are just fast as can be, flitting here and there, from flower to flower, excited about the next, and the next, and the NEXT bit of nectar! These days, they're happy to sit on each petal and suck it all down for everything its worth. 'Til it's sucked dry.
October Connecticut flowers are like 2 am Last Calls: Earlier than you'd like but later than some places, lol.
