~ 9th April 2018 ~

From Peter Law: "06-Apr-2018: Whilst gardening in the sunshine today at King's Copse Park, Garsington, Oxon I witnessed two male Large Whites emerge from underneath my park home. Both flopped onto nearby blooms, then after a few minutes flew up and away. I thought this was early and having just checked the sightings log find this may be the year's first sighting. Last autumn there was a huge brood of Large White larvae on weeds just outside the boundary fence and as one panel was down many of these pupated on the walls of my home. All of those were eaten by birds but it seems some that concealed themselves effectively have survived to adulthood."

~ 8th April 2018 ~

From John Lindley: "06-Apr-2018: Sightings from Goring-on-Thames, Oxon today were one very small male Green-veined White, 10+ Brimstones including two females, one Peacock and one Small Tortoiseshell."

~ 7th April 2018 ~

From Dave Wilton: "06-Apr-2018: There was just enough hazy sunshine to walk my first butterfly transect of the year this afternoon in some private woodland near Grendon Underwood, Bucks. 25 individuals from three species (Brimstone, Small Tortoiseshell & Comma) was just about as expected, although I was disappointed not to find a Peacock. Don't tell Nick Bowles, but I committed the cardinal sin of stopping the transect for ten minutes when I saw a pair of Commas chasing each other through some quite dense low-growing vegetation. The female then settled and after a very quick "antennae massage" from the male they paired up at the base of an ash sapling and were then very tolerant of me pulling numerous grass stems out of the way to get the picture below."

From Dave Cleal: "05-Apr-2018: 1 Peacock and 1 Tortoiseshell along the Roundmoor Ditch on Dorney Common, Bucks today."

From Mark Griffiths: "05-Apr-2018: After a few Brimstones earlier this year we had a male Brimstone, two Small Tortoiseshells (one in hot pursuit of the other), a Comma and a Peacock in our garden in Garsington, Oxon (SP580023) today."
