Armed with my 90’s and 95’s in high school math, and my ‘D’ (Yep!) in college Calculus, I have endeavored to determine what fraction of Americans have ever seen this one in the wild. The results of my exhaustive research provide the shocker, some one in 54,000 of us have seen a Regal Fritillary Butterfly in its prairie habitat. That’s 0.000018 of us.
We had to take account of the extraordinary rarity of Regal Frits east of the Mississippi River, they found in just 2 different prairie/wet meadow habitats in Pennsylvania and Virginia. West of the Mississippi, their range is extensive, found from Oklahoma to Dakotas, but know that their habitat west is very, very localized.
I saw this male in the extensive meadows at Ft. Indiantown Gap Military Reserve, not far from Penn State University. I registered for the annual 4-days in June summer Open House at Ft. Indiantown Gap, and it was so worth it. The sun shone all day, and the Regals put on a show, accompanied by Monarchs, Coral Hairstreaks, Great Spangled Frits and more.
I did not want to ever have to pack it in (cease my field work) without having introduced myself to these splendid butterflies. I am among the one In 54,000.
