How many Palamedes Swallowtails did we see those 5 days in Florida’s Big Bend Wildlife Management Area? I’d say 65 to 75 Palamedes. Spicebush Swallowtails? More than 5 Spicebush. Tiger Swallowtails? A good 10 or so. Georgia Satyrs? Some 15 or more. What I think were Zabulon Skippers? Probably 20 Zabulons. Viceroy Butterflies? About 20 Viceroys.
When I saw my first Gulf Fritillary, on our 4th day in the field, I was triggered. April 11, 2019, in the Florida Panhandle, and all we’ve seen was one (!) Gulf. When we climbed back into our truck the next day, April 12th, our Gulf Frit counted stood at that one Gulf Fritillary. Sunny, days, highs by 1:30 PM reaching 81F, and just that one Gulf.
I tossed that around in my head, and I’m still weighing the criteria. Passionflowers, the hostplant for Gulf Fritillaries were not seen anywhere that week, not in any of the diverse habitat that Big Bend boasts. Glassberg in his A Swift Guide to the Butterflies of North America cites them as “most common in late summer/fall.”
The Plan always impresses me. There is complex timing for all you’d see in such a destination as Big Bend WMArea. Regretably, the No-See-Ums (Sandflies ?) seem to resist such restraints.
This sweet Gulf here was seen in 2018 at Harris Neck National Wildlife Refuge along the Georgia coast in August, where there were then, legions like him, on the wing.
