   We held the Catahoula NWR NABA Butterfly Count on August 1st this year. The count organizer was Craig Marks, and there were 9 participants: J. Clark, B. Kaufman, C. Marks, B. Moon, D. Patton, R. Seidler, J. Trahan, J. Trahan, P. Wallace. Due to the COVID situation, with did things a little differently this year. Parties traveling together on the count stayed in separate vehicles, and of course folks were careful to maintain a safe distance from one another when butterflying the same area on foot. The participants divided up into from 2 to 5 parties, depending on location and time.

   The count circle is centered at the NWR HQ and covers an area 15 miles in diameter in La Salle and Catahoula Parishes. This includes the Headquarters, Willow Lake, and French Fork Units of the NWR and portions of the Bushley Bayou Unit, as well as many areas not on the refuge. Much of the circle is bottomlands, with the habitats including bottomland hardwood forest, secondgrowth, fields, wetlands and bodies of water. There's also significant upland areas in the northern part of the circle, where the dominant habitat is "piney-woods"--largely pine plantation--with hardwood creek bottoms. Less of the upland area is accessible to the public, being mostly private land and with houses along much of the public roads. Areas we covered this year include the Headquarters, Willow Lake, French Fork (Muddy Bayou Rd) and Bushley Bayou (Minnow Ponds Rd and Dry Bayou Rd) Units of Catahoula NWR, the Archie/Little River Recreation Area, and for the uplands Blade Loop Road.

   This year's count had an inauspicious beginning, with overcast skies and a drizzling rain for a little while. Butterflies were generally hard to come by for the first couple of hours. However, the rain stopped soon enough, and before noon the skies were sunny. With the sun came the butterflies, and we ended up with a decent number of individuals and species.

Zebra Swallowtail, seen by the Trahans, was a new species for the Catahoula count. The 85 Gulf Fritillaries seen this time was a high count for this species on the Catahoula NWR count. Silvery Checkerspots (found in the upland area) were much less common this year than on the 2019 count when they were surprisingly numerous.
