I planned to meet up with Tom Stock yesterday morning in the Frederick Municipal Watershed Forest off Gambrill Park Road in Frederick Co., but a late start and traffic snarls on I-70 east of Frederick had me pulling up at 10 am, just as Tom was coming off the trail after successfully scoring three FOY Edwards’ hairstreaks in the weedy fields and scrub oak where they’ve been observed for some years. Somehow I couldn’t manage to convince him to walk back to the fields again, and anyhow it was getting even hotter and the hairstreak show would most likely be over for the day — they tend to stay low and visible only early in the morning. But I decided to give it the old college try and headed off down the trail.
Very little else was flying; I did see two cloudless sulphurs, common wood nymphs, and both current duskywings, Horace’s and wild indigo. But despite our concerns about it getting too late in the day, I picked up one Edward’s — pretty worn — as soon as I entered the field where we usually find these hairstreaks. Over the next hour, in between picking and eating a lot of blueberries, I managed another four Edwards’ — two worn like the first one, and two fairly fresh. The last one I saw was around 1130 hours, and I was ready to head back to the car’s A/C.
I left Frederick Forest at about noon to twitch for the great white heron that has been reported in Ft. Frederick State Park near Big Pool in Allegany County. It was a ridiculously easy find, standing in plain view of the road in the beaver pond near the campground. Butterfly hunting around the beaver pond train was, to be gracious, uneventful. Saw very few leps the rest of the day, but I still had an Edwards’ and white heron celebratory dinner at the Hancock Park ‘N Dine (where one can spend a lot of the meal trying to identify the British butterflies on the menu and wallpaper).
