Despite the strong winds, most of the RPS Nature Group on an outing to Sharpenhoe yesterday managed to photograph two of the target species - the Chalkhill Blues (all males so probably early in the season) and Dark Green Fritillaries (getting a bit worn and mainly females so late in their season). However, the favourite was a Brimstone male emerging from its cocoon. Also shown Large Skipper, Red Admiral, Small White and Holly Blue.
