I've been away for a couple of days. Yesterday, I visited Flag Fen near Peterborough, where I spotted a Small Tortoiseshell along with several Whites.

Later that same day, I went to Grimes Graves near Thetford. I saw 3 Common Blue butterflies chasing one another as I walked across the car park. Common Blue and Small Heath butterflies were plentiful.

I also saw a couple of small brown butterflies, possibly Dingy Skippers but I'm not sure, and in the distance a Brimstone butterfly.
I did manage to get a photograph of one of the Cinnabar Moths at Grimes Graves; these are day-flying moths often mistaken for butterflies.

At this time of year, you will see more butterflies out in the countryside than in the garden. However, my husband reports a blue in my garden today - possibly a Common Blue butterfly.
