Putney Heath - classic heathland scene with flowering Heather (Calluna vulgaris), and Silver Birch in the distance
Silver Birch with Heather beneath on a damp part of Wimbledon Common
Heathland succesion at the margin of a damp glade - Gorse, Silver Birch and Aspen (or a similar-looking Poplar hybrid) gaining ground amongst Heather
The more notable plants included Tormentil, a Cudweed species, several Meadow Vetchling, a single Agrimony, a couple of ditches in close proximity containing runs of Blackberry with more ferny than usual 'Oregon Thornless' type leaves and a Downy Birch.
The weather was patchy, sometimes rather overcast, so not many butterflies were seen. A Gorse Shield Bug (Piezodorus lituratus) was found. Also several kinds of Odonata. A Migrant Hawker settled on Gorse. A Common Darter was seen. A close view was had of a pair of tandem Ruddy Darters ovipositing amongst grass on a damp pathway. 2 or 3 (Large) Red-eyed Damselflies were utilising an isolated patch of Heather, away from water, with a Gorse plant in it.
I wasn't paying much attention to birds but a Jay was spotted.
As I left the north end of Putney Heath there was a heavy downpour, but I managed to avoid getting too much of a soaking by getting to a sheltered bus stop. Later in the afternoon large amounts of water were noted pouring off the ends of the modern, but badly designed glass roof at the entrance to East Croydon station. Any sensible set-up would be capturing that water for later use.
