As the weather forecast was good, I decided to catch a bus out to the White Peak this morning. I alighted at Calver Sough and had a leisurely stroll up Coombs Dale, looking for wildflowers and butterflies.
Coombs Dale is not as picturesque as some of the other Derbyshire Dales, having been the scene of much mining and quarrying in the recent past. As a result, it's not very popular with walkers and tourists - I didn't see more than half a dozen people all day.
Coombs Dale is a particularly good spot for butterflies. It contains just the right mixture of habitats - open grassland with an abundance wildflowers, plus woodland, scrub and ruderal herbs.
The dale's 'speciality' is the dark green fritillary (Argynnis aglaja). The best time to see them is mid-July, but there were still quite a few around today. Many of them were rather pale and tattered, indicating that their flight period is nearly at an end.
The dark green fritillary is a difficult butterfly to photograph. It flies very fast and seldom seems to settle for more than a few seconds. I got several shots of dog-eared individuals that looked as if they were on their last legs. I eventually managed to get one half-decent picture of a fresh specimen. You can just about make out the dark green colouration at the base of the underwing, from which the species gets its name.
