2015 has been an interesting year for the butterflies of Dorset, we've even had two separate sightings of the rare Long-tailed Blue (Lampides boeticus) in what has been named nationally as the second largest influx of this species to the UK!

The recent mild autumnal weather has given rise to a number of late sightings including a Speckled Wood and two Clouded Yellows on 1st November.
