Colin Mather sent this news: "16-Feb-2018: Found today a dead Green-veined White in Henley-on-Thames, Oxon in good condition." [NB this doesn't count as a first sighting because the butterfly wasn't seen flying outdoors. David]

Paul Bowyer and Karen Roberts sent this sighting: "16-Feb-2018: We saw a Red Admiral in our back garden at Flackwell Heath, Bucks (SU894897) this morning and wondered if there were any nectar sources close by. We got the answer in the afternoon when we saw it in the front garden on winter flowering heather. It must have been with us for a few hours."

Jed Cleeter reported on oxonbirding.blogspot.co.uk that he saw a Comma at Fyfield Wick, Oxon on 16th February.

Paul Lacey sent this sighting: "02-Feb-2018: I had an immaculate specimen of a Red Admiral flying in my garden on Woosehill in Wokingham, Berks at 1pm today. Quite a surprise, though at least one was in my shed last year over winter."

John Lindley sent this news: "28-Jan-2018: I saw a Male Brimstone, flying in the sunshine this morning on a footpath in Little Stoke, Oxon. Also of interest, a small area with several active Buff-tailed Bumblebees - there must have been a nest nearby."

Judy and Terry Wood sent this news: "23-Jan-2018: We were surprised to see a Red Admiral flying in the garden at Little Chalfont, Bucks as it was drizzling and breezy. We assume it had been disturbed from its slumbers but it looked like it disappeared into a large dense conifer so hopefully soon found some shelter."
