Cheers, Wurzel - I'm beginning to think that these late season Small Whites are all appearing with dusky and cryptic markings just to get your attention!

There haven't been more than a small handful each day either. Common Blues have carried on into November in both the last two years, so maybe they will again - they've certainly had a good October again this time round (though the usual banker blue species, the Hollies, have been uncharacteristically absent since the start of the month).
Thursday 17th October was probably all you could ask for at this time of year - lots of sunshine and temperatures up to 19 degrees. The remaining butterflies responded to the sun, and I counted 32 of 7 different species on my local ramble today.
Red Admiral 14
Speckled Wood 6
Common Blue 3
Peacock 3
Small White 3
Small Copper 2
Large White 1
Several of the Red Admirals were seen in flight again, but the majority were making the most of the ivy, which was fast going over now.

- there are four in this view
For some reason, Peacocks don't seem to go for ivy nectar, and prefer lower growing sources.

- symmetrically damaged hindwings - one to recognise after hibernation if it makes it through
The Specklies were starting to look a bit tired, though the others I saw today were in two sets of tussling males that appeared to still have plenty of energy.
Another Small White for your consideration, Wurzel...
One Common Blue today was reasonably whole...
...but a second had seen better days...
The third one settled on the "wrong" side of me, so I took some unconventional views
from underneath.
I had seen the venerable Small Copper again, but it was busy in the sunshine chasing the second of the Common Blues which had dared to nectar on its personal ragwort plant. Consequently I didn't get any more photos, and sadly this was its last appearance. However, right at the end of my walk, close to the spot where the damaged Peacock was nectaring, a bright red blur caught my eye - a female Small Copper. It settled to nectar on a dandelion, but annoyingly quickly shut its wings and sat end-on to me.
I managed to get one better shot before it flew off at speed along the bottom of the hedge and I lost it against the sun.
The last time I saw a Small Copper on this bit of my local patch was in July last year, though they have turned up here sporadically over the years. There is certainly plenty of healthy sorrel around, so with luck the butterfly was on an egg-laying mission.
As ever, there is always some little extra something to make the walk memorable.
