 Not at the lake – I was not there to see the colourful sunrise. This as I left home.

Most days there are still as many as six Song Thrushes singing away around dawn. This one is getting on with the task of feeding.

I am getting better: my sharpest Common Marble moth Celypha lacunana to date.

Better than yesterday's Small Fan-footed Wave moth Idaea biselata, here on one of the street lamp poles.

Short-cloaked Moth Nola cucullatella. Apart from one in the Priorslee Avenue tunnel on 8 July 2014 this, on a street lamp pole, is my only Shropshire record of this species.

This is a braconid parasitic wasp of genus Meteorus. Note the long ovipositor indicating it is a female.

This view shows the ovipositor more clearly.

A sharper image of one of the long-legged flies. Note that, unusually for flies, the modified hindwing forming halteres is visible beside where the hind-leg joins the abdomen.

A different species of long-legged fly.

A stubby-looking tiny fly. The colour seems to be interference patterns rather than base-colour.

Yet another unidentified fly.

And another. This one with a small head and thick thighs on all its legs, especially the hind legs.

I photographed one of these small, hairy flies that sits with wings held well apart yesterday. This is a much better photo.

 Last unknown fly for the day. About time Obsidentify got to grips with this group of insects.

A tiny midge hanging upside down. No idea as to species.

Note the length of the antennae on this insect.

From this angle the antennae do not show but do help to identify it as most likely a Mirid bug Campyloneura virgula.

A Harlequin Ladybird Harmonia axyridis of the form succinea..

A Common Red Soldier Beetle Rhagonycha fulva on a street lamp pole some way from any....

...Common Hogweed Heracleum sphondylium where they can live up to their recently given name of Hogweed Bonking-beetles.

Poor thing. A dead (European) Mole Talpa europaea. No idea about the cause of death. One fly has already started work on disposing of the body.

A tiny spider that seems to be a very young Garden Spider Araneus diadematus. All adult spiders grow throughout this part of the life-cycle, shedding their exoskeleton regularly. I am unsure what is alongside the spider: could it be the egg that the spider has just emerged from?

Another tiny spider. This long-legged spider is climbing through the hairs on the back of my hand, hairs that I have trouble seeing with my eyes. The palps on the spider indicate it is a male.

A morning when I decided to get to grips with identifying thistles. This is a Spear Thistle Cirsium vulgare.

Whereas this is a Marsh Thistle Cirsium palustre.

And a Creeping Thistle Cirsium arvense.

In the Priorslee Avenue tunnel:

Nothing of note

The Flash: 06:15 – 07:10

(148th visit of the year)

Bird notes:
- the adult pen Mute Swan seen with her three cygnets briefly before they disappeared, presumably inside the island. The cob was visible most of the time chasing geese. The extra swan that lurks out of the way was not seen.
- some of the Tufted Duck were sitting on the island. More out of sight?
- fewer Coots noted today as the light-level was not so good as yesterday for separating those standing close together.

Bird(s) noted flying over here:
- 1 Lesser Black-backed Gull
- 1 Jackdaw

Hirundines etc. noted:
- 2 Swifts
- 7 House Martins

Warblers noted (the figure in brackets relates to birds heard singing):
- 3 (2) Chiffchaffs
- 3 (3) Blackcaps
'nominal' warbler:
- 1 (1) Goldcrest

Noted on / around the water:
- 218 Canada Geese
- 68 Greylag Geese
- no Canada x Greylag Goose
- 2 + 3 (1 brood) Mute Swan
- 32 Mallard: sexes not determined
- 10 (9♂) Tufted Duck
- 5 + 4 (4 broods) Moorhens
- 55 + 2 (2 broods) Coots
- 2 Great Crested Grebes

Noted elsewhere around The Flash:

Moths:
- *!!Foxglove Pug Eupithecia pulchellata
- *!Barred Red Hylaea fasciaria

Beetles:
- Alder Leaf Beetle Agelastica alni: adult

I cannot find any previous entries in my logs for Foxglove Pug moths Eupithecia pulchellata which this is.

This moth is a Barred Red Hylaea fasciaria. It is certainly barred: it is not very red.
