Back to Mercer County Park later in the afternoon; I am combining sightings from the power lines area and the “abandoned roadway” area. There was a sustained 15 mph wind and it was mostly sunny and 91º F at 3:15, when I arrived. I spent 45 minutes at the power lines and another hour at the roadway. At the power lines there were 3 Falcate orangetips, 1 Eastern tailed-blue, 1 Spring Azure and 1 Juvenal’s duskywing; all the other butterflies were from the abandoned roadway and surrounding wooded areas. Nearly all were females (18 of 22 overall). There was one fly-by swallowtail (fortunately it was a Black Swallowtail male - easily identified).
