Large Red Damselfly
This is also good spot for butterflies, especially two fritillary species. I tracked down five Small Pearl-bordered Fritillaries and a lone, strong-flying Dark Green Fritillary too. There'll probably be more of these around in a week or two.
Small Pearl-bordered Fritillary
Dark Green FritillaryA few other common butterflies were on the wing, and a little later in the morning I got another Small Pearl-bordered Fritillary at Penrhiwfer. No Marsh Fritillaries though. A huge Golden-ringed Dragonfly wouldn't keep still for a photo and neither would a Burnet Companion moth.
