Every September, many local lepidopteraphiles (butterfly lovers) make a pilgrimage to the
Flat River Waterfowl Impoundment in north Durham county, North Carolina. Located just north of Historic Stagville along Old Oxford Highway, the impoundment offers a gravel loop trail through wetland habitat. The area abounds with alternate wingstem (
Verbesina alternifolia), passionflower (
Passiflora incarnata), (
Helenium amarum), and willows (
Salix spp), all of which are attractive to adult butterflies or their larvae.

Today, as we started walking the trail at the Flat River Waterfowl Impoundment, Buckeyes frequently intercepted our path. Occasionally, they were accompanied by Clouded Skippers. In years past, we have seen a much larger number and variety of skippers, although we often go two to three weeks later in the season.

Further down the trail, a large willow -- which we call "the butterfly tree" -- was alive with Hackberry Emperors and Horseflies gleaning sap. Beneath the willow, a Question Mark hung upside-down from a blackberry (
Rubus spp).

Dung piles are excellent microhabitats for beetles, flies, and butterflies. On one pile of raccoon scat (filled with crayfish and persimmon seeds), we found a Viceroy and Hackberry Emperor competing for the rich trove of much needed nutrients, included salts and amino acids.

As the morning heated up, we were greeted by the bright orange of the Fiery Skipper. We also saw three Variegated Fritillaries near blossoming
Passiflora incarnata, a known host for Variegated Fritillary caterpillars.

This is a great walk, indeed - wonderful pictures. When I went in July I was too tempted by the multitudes of blackberries just across the ditch of the gravel road - since I didn't shower til bedtime, I ended up with about 100 red bug bites! My fault, and it is a fine natural area to explore.
