Priorslee Lake and The Flash

15.0°C: Low cloudy tended to lift somewhat and even threatened to break as I was leaving – but didn't. Light / moderate ENE wind. Very good visibility.

Sunrise: 05:16 BST

* = a photo today

Priorslee Lake: 04:15 – 06:00 // 06:55 – 09:00

(156th visit of the year)

Bird notes:
- Some adult Coots presumably hiding in the reeds? Low number today.
- A second pair of Great Crested Grebes have at least one juvenile. The original pair had both their juveniles on the water this morning.
- A Peregrine blasted through at 05:35 scattering the Black-headed Gull (which I am sure it wasn't interested in) and disappeared.
- The 'new' Sedge Warbler was not seen or heard. One of the breeding pair was seen carrying food, with another seen in flight close-by.

Fungus
- I have been unable to relocate the fungus I photographed on Thursday to update the identification

A long-range blurred special. Just about visible is at least one juvenile on the back of the furthest Great Crested Grebe – the second pair to produce this week.

Our nesting Sedge Warbler trying to sneak in to feed its young with a big beakful.

I stood stock-still and it started to move around again.

One more photo and I retreated to let it get on with feeding its off-spring.

All the warblers are getting a bit worn as the end of the breeding season approaches. They will soon be moulting to get new feathers for the flight to their winter quarters. I would expect this to be a female Common Whitethroat as a male was still display-flighting very close. It shows no hint of being a juvenile.

I was hoping this would be a Silky Wave but not so. It may look 'silky' but that species lacks the black spot in each wing so it is yet another Small Fan-footed Wave (Idaea biselata).

And for a change a different Small Fan-footed Wave taken by natural light. Not sure I have ever seen one in the day previously.

My first Cinnabar moth caterpillar (Tyria jacobaeae) on its preferred food-plant Common Ragwort (Jacobaea vulgaris). In real life it is more yellow-toned than it appears here. I have no idea why as the Ragwort looks the correct colour. I had never appreciated that the caterpillar has white hairs sticking out.

A Dun-bar moth (Cosmia trapezina). Variable in the amount of contrast forming the dun-bar but the shape of the cross-lines narrowest where the wings join is consistent.

It is a good job that Honey Bees (Apis mellifera) are not at all aggressive. Did you realise they were so fuzzy?

Not everyone will agree this is a better view of this strikingly marked Noble False Widow spider (Steatoda nobilis). I wonder if the users of the sailing club shelter realise what is lurking in the corners?

A rear-end view of one of the Leiobunum rotundum/blackwalli harvestman. The black saddle means this is a female. Those are not eyes on stalks they are the palps sticking out at the front of the insect.
