Priorslee Lake and The Flash

11.0°C > 17.0°C: Overnight rain clouds clearing to the East. Then variable amounts of cloud with some good sunny spells. Moderate and fresh-feeling north-westerly breeze. Excellent visibility.

Sunrise: 04:49 BST

I have run out of rime; a selection of photographs from today will be included in tomorrow's blog.

+ = my first sighting of this species at this site this year.
++ = new species for me at this site.

The overnight rain, cooler temperature and brisk wind reduced the number of moths seen.
