September 2024
Monday 23rd . Today wasn’t the best day to be out chasing butterflies, lots of cloud, some of it heavy enough to cause showers and a strong wind just in case that wasn’t enough! Nevertheless, temperatures didn’t look too bad, so I set off to explore the sea wall near East Tilbury. I have David Lazurus’s sterling and heroic work for tipping me off to the site, I thought I did a lot of walking! I didn’t realise just how close it was to Cliffe Pools in Kent, which gets a fair bit of mention on the Kent butterfly group on Facebook, including the Pale Clouded Yellow a few years back.
Anyway, despite the weather I had a little bit of activity walking from the station, some Whites to start with, then a Red Admiral and a few Speckled Wood.
Just approaching an open, rather desolate looking field I disturbed a few of one of the targets, some Walls. They’d obviously come out during an earlier sunny spell and now every one I disturbed scarpered out of sight.
From there it was just a 5 minute walk to the sea wall where David had reported some sort of Wall Nirvana. Sadly my arrival coincided with an extended gloomy spell and the was little activity to be found as far as butterflies were concerned but peering over the sea wall I saw the tide was out and lots of Avocet were working the mud flats and shallows.

- Later in the afternoon when the sun was out and the tide was coming in.
Thankfully the cloud thinned enough to wake up some butterflies and precisely where David recorded his Walls, I started finding them.
I was also here to look for the Clouded Yellows that David had recorded but they were nowhere to be seen. Common Blue, Small Heath and a few Whites were active though.
The weather improved as the afternoon wore on, and although the wind didn’t ease up the Walls came out in significant numbers and with so many about, amorous males were bound to stumble across passing females, some encounters more successful than others.
As the sun sank down in the west, Walls were glued to the wall which here faces due west. Curiously they were mostly females.
Most definitely worth the trip, thanks Mr. Lazurus
