Porterweed and a Zebra Heliconian

Drinking coffee, looking out the kitchen door, I saw this Zebra Longwing flopping about my garden this morning. I followed it for a bit as it flitted around my Blue Porterweed. For what I was trying to do—capture something in motion in filtered light—my aperture was too wide and my f-stop too slow, but it turned out a pretty cool effect. They're such slow-moving, easy-going butterflies (unlike most Swallowtails), it's easy to get a closeup shot, as I did below.
