Priorslee Balancing Lake and The Flash

16.0°C > 18.0°C: Mostly cloudy, often at low level. Beginning to lift and break after 09:15. Light north-westerly breeze. Good visibility.

Sunrise: 05:30 BST

* = a species photographed today
! = a new species for me here this year
!! = a new species for me in Shropshire

Priorslee Balancing Lake: 05:35 – 06:15 // 07:05 – 09:35

(167th visit of the year)

A delayed start with remnant of promised thunderstorms keeping me away.

Bird notes:
- I cannot recall when there were last as many as 24 Mallard here. Most seem to have finished their wing-moult and are able to fly. None is showing any real sign of acquiring breeding finery, Neither can I locate any of the late-hatched juveniles.
- It seems the Reed Warblers have had a good breeding season, at least so far as the noisy current number of juveniles begging.
- I have seen no Swifts here for a few days now. There were chasing groups of up to 15 birds around their breeding site in Newport on Tuesday (30 July). They seem to have gone now. This species is one of the last Summer visitors to arrive and the first to go and they have probably mostly departed. Any birds that had replacement broods could be seen for a few weeks yet.

Hardly sunrise. Rain delayed my arrival.

A Straw Grass-moth Agriphila straminella trying to hide - as they do. I was only able to positively identify less that a quarter of the grass-moths that were exploding from the vegetation in front of me. This was the best-marked example I found.

This one is somewhat worn. I have no idea why they rest with their antennae pointing upwards. Perhaps they get better reception.

One that has been in the wars and is missing part of a wing.

 Another with a chunk of wing missing and a very worn example. In many species of moth the imago (the flying stage of the life-cycle) does not feed and its sole job is to mate with the female then laying the next generation's eggs. It will typically live less than a week though some, usually larger species, survive longer and these species may well feed on nectar.

Not a good photo of an ichneumon but all I could manage. The insect has its head turned through 90 degrees toward me. The wasp waist shows well.

The only large hoverfly of the day – a male Common Dronefly Eristalis tenax.

A Common Twist-tail Sphaerophoria scripta visiting Meadowsweet Filipendula ulmaria with wings akimbo...

...and wings closed.

This fly is apparently one of the Limnophora sp. I am little the wiser.

Another fly to test me. It is Meiosimyza rorida in the family Lauxaniidae. Er? So I looked it up and was informed it is a family of acalyptrate flies. I am none the wise. I can say that it looks like a very small version of the Muscid fly Phaonia pallida. The flower is one of those on an umbel of a Common Hogweed Heracleum sphondylium.

One fly I can identify. It is my first Grass Fly or Yellow Swarming Fly Thaumatomyia notata of the year. They are very small.

 I wonder what this was before it was eaten? The strength of the veins suggest Alder Fly though that species ceased flying many weeks ago.

 This tiny creature on a petal of Greater Bindweed Convolvulus sylvaticus is called a Potato Leafhopper Eupteryx aurata though quite why is unclear as it is very common(ly overlooked) on all types of vegetation.

This bug was sprinting across the leaf and about to run around to the underside – where it wasn't when I looked. It is most likely a Common Flower Bug Anthocoris nemorum though the genus contains several species that are 'problematic'.

An instar of a Common Green Shieldbug Palomena prasina.

One of the Long-jawed Orb-web Spiders Metellina sp.

I have no idea what this is. I noticed on the underside of a leaf where it seemed to have a pair of claspers at one end – I have no idea which might be front or back. Is it a chrysalis? Whatever it is / was it appears to be tied down by a spider's threads.

Dead on the path I noted this small mammal. I believe it to be a Water Shrew Neomys fodiens. The sharp contrast between the upper and lower coat and especially what seems to be white hairs on the underside of the rail seems to clinch the ID. I used both Obsidentify and Google Lens to try and identify it. Granted the specimen is a bit mangled but Obsidentify suggested "Caspian Gull"! Google Lens was slightly better suggesting Black Rat. I cannot recall seeing this species before, alive or dead. I fear it may be a victim of one of at least three cats that are now prowling the neighbourhood. Cats and wildlife do not mix.

In the Priorslee Avenue tunnel:

Flies:
- *5 cranefly Tipula lateralis

Other things:
- 16 White-legged Snake Millipedes Tachypodoiulus niger

The pale line down the centre of the abdomen and the markings in the wings identify this as the cranefly Tipula lateralis. Without ovipositor it is a male.

Somewhat confusing with shadow from the camera flash but here are a pair mating.

The Flash: 06:20 – 07:00

(170th visit of the year)

Bird notes:

Bird(s) noted flying over here:
- 2 Lesser Black-backed Gulls

Hirundines etc. noted:
- 2 House Martins

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

Noted on / around the water:
- 16 Canada Geese
- 2 Greylag Geese
- 2 + 3 (1 brood) Mute Swan
- 20 (?♂) Mallard
- 35 (?♂) Tufted Duck
- 4 + 3 (2 broods) Moorhens
- 58 + 3 (2 broods) Coots
- 2 Great Crested Grebes
- 1 Black-headed Gull

Noted elsewhere around The Flash:

Moths:
- *Garden Grass-veneer Chrysoteuchia culmella

Bees, wasps etc.
- wasp sp.: either German Wasp Vespula germanica or Common Wasp V. vulgaris

Spiders, harvestmen etc.
- 1 harvestman Dicranopalpus ramosus/caudatus

A very worn grass moth. I can detect the hint of a diagonal line toward the wing-tip which makes it a Garden Grass-veneer Chrysoteuchia culmella. This species has just about finished its flight period so it is not surprising that any still around would be worn.
