Priorslee Balancing Lake and The Flash

13.0°C > 16.0°C: Cloudy after overnight rain. A clearance from the West was making slow progress and just about reached here when I had to leave. Brisk moderate even fresh north-westerly breeze. Excellent visibility.

Sunrise: 04:51 BST

* = a species photographed today
$ = my first sighting of the species for this year
$$ = my first ever recorded sighting of the species in the area

Priorslee Balancing Lake: 05:05 – 06:20 // 07:35 – 09:25

(162nd visit of the year)

Bird notes:
- the Canada and Greylag goslings all still present and correct.
- on the last few mornings both Mute Swans have been together as I arrived but thereafter the pen disappears, I assume to the nest site. Why? Surely the eggs, if any, will not now hatch.
- again only two groups of Mallard ducklings seen: today those with four and a single duckling. It is possible that two of those counted as adults are actually fully-grown juveniles.
- the duck Pochard had made her way to the East end of the water. Could this mean that as she undertakes her annual moult she will be able to fly again?
- the Little Grebe heard only once and calling very quietly.
- I still could not determine how many juveniles were with the third pair of Great Crested Grebes.
- a Common Kestrel flew West along the length of Teece Drive and away c.07:45.
- very few corvids (Jackdaws and Rooks) passing, most being a group of 16 Jackdaws inbound at 05:40.

One of the latest brood of Great Crested Grebes appears to be something of a back-seat driver.

A moulting second year Lesser Black-backed Gull. Three and a half inner primaries are regrown with the adjacent few missing and yet to regrow with the four outermost still to be dropped.

A new moth species for me identified thanks to the Shropshire recorder. It is a Common Knapweed Tortrix Eucosma hohenwartiana . Snazzy species name! Perhaps derived from German "hohen" = "high"; "wart" = "guard or lookout"; "iana" = "associated with". So a moth looking out from high up? Must be correct - Google's AI says so.

Another view.

A moth from a group that is very difficult to identify unless the specimens are very fresh. I think this is a Common Grey Scoparia ambigualis.

This a male Small Skipper Thymelicus sylvestris. Note the scent gland in the forewing is curved and longer than on the Essex Skipper T. lineola in yesterday's photos.

A more-or-less pristine Speckled Wood Pararge aegeria. It won't stay that way long. A punchy species always battling to control its territory.

Do I need to say? Red Admiral Vanessa atalanta

"Please sir: may I..." Actually this Chequered Hoverfly Melanostoma scalare is using one of its legs to clean its eye and not asking to be excused.

Not commonly seen though there must be many: this is a male Chequered Hoverfly with the more quadrate yellow spots (the female's are triangular)

One of the most distinctive hoverflies: a Pellucid Fly Volucella pellucens.

A very distinctive small fly which seems only to have a scientific name – Dryomyza anilis.

A Common Nettle Bug Liocoris tripustulatus.

I nailed this one! This Harlequin Ladybird Harmonia axyridis is of the form conspicua with one orange spot on each wing, the spots often sullied with some dusky markings just off-centre. Just about visible here.

A Rough-haired Lagria Beetle Lagria hirta

On one of the street lamp poles there were four male harvestmen from the species pair Leiobunum blackwalli / rotundum. males are impossible to separate unless you can see the eye surround. Not here! Three obvious individuals and a few legs of the fourth at the top.

In the Priorslee Avenue tunnel:

Moths:
1 Slender Pug Eupithecia tenuiata
1 unidentified pug Eupithecia sp.

Hoverflies:
1 Hornet Hoverfly Volucella zonaria [Hornet Plumehorn]

Other flies:
1 Muscid fly
6 moth flies Psychodidae sp. [Drain Fly or Owl Fly]
15 midges of various species.

I cannot get an identity for this pug moth from the Eupithecia group. Google Lens thought Common Pug Eupithecia vulgata. I am not sure.

Not a species I expected to be asleep in the tunnel: a Hornet Hoverfly Volucella zonaria.

Or for that matter this unidentified Muscid fly.

The Flash: 06:25 – 07:30

(160th visit of the year)

Bird notes:
- the geese were all together though with the Canada Geese separated from the Greylags so today's totals are probably my most accurate of this year's moulting season. There is the lone mainly white goose but none of the usual Canada x Greylag hybrids.
- six adult Mute Swans remain.
- the late brood of two Mallard ducklings not seen. A few of the Mallard still have enough flight feathers to manage to sit on house roofs/
- among a group of ten Tufted Duck was a drake Pochard: a strange date to see this species which is usually a mid-winter visitor (though this species does breed in the Midlands in small numbers]
- twelve Tufted Duck all-told.
- still only two Great Crested Grebes noted.
- a trio of Lesser Black-backed Gulls arrived, staying only briefly: two adults and a second year bird.
- the Great (White) Egret noted again.

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

Noted on / around the water:

- 12 (10♂) Tufted Duck
- 4 Moorhens
- 54 + 7 (three broods) Coots
- 2 Great Crested Grebes
- 3 Lesser Black-backed Gulls
- 1 Great (White) Egret

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

Noted around the area:

Butterflies:
none

Moths [on street lamp poles and in the grass]
1 Riband Wave Idaea aversata
1 Garden Grass-moth Chrysoteuchia culmella [was Garden Grass-veneer]
1 $ Common Zebra Moth Helcystogramma rufescens [was Orange Crest]
2 $$ Coleophora species: not further identifiable from photos
both of these with help from the recorder.

Bees, wasps etc.:
Honey Bee Apis mellifera
Buff-tailed Bumblebee Bombus terrestris

Hoverflies:
Marmalade Hoverfly Episyrphus balteatus
Chequered Hoverfly Melanostoma scalare [Long-winged Duskyface]

Dragon-/Damsel-flies:
none

Other flies:
numerous different midges and flies

Bugs:
Common Flower Bug Anthocoris nemorum

Beetles:
larvae of Alder Leaf Beetle Agelastica alni
Harlequin Ladybird Harmonia axyridis var. succinea
Rough-haired Lagria Beetle Lagria hirta

Common Red Soldier Beetle Rhagonycha fulva [Hogweed Bonking-beetle]

Spiders, harvestmen etc.:
*$ harvestman Dicranopalpus ramosus/caudatus

New flowers for the year:
$ Hemp-agrimony Eupatorium cannabinum

This moth is one of two from the Coleophora species group. These small moths are not further identifiable from photos and indeed their presence is most easily determined from the unique pattern the larvae of each species makes as it mines leaves in its food plant.

A Common Zebra Moth Helcystogramma rufescens characterised by the long palps curving back over its head. It was known as Orange Crest when the orange is miniscule and soon wears away. I am not sure "Zebra" is any more appropriate!

A soggy bee after the overnight rain. I am not sure I can identify it for certain.

Only a Marmalade Hoverfly Episyrphus balteatus but a pleasing view.

My first White-clubbed Glasswing hoverfly Scaeva pyrastri this year. The older name Pied Hoverfly seems somewhat more appropriate. A Common Red Soldier Beetle Rhagonycha fulva gate-crashes the party.

The Common Red Soldier Beetles love Common Knapweed Centaurea nigra. The photo revealed a hitherto unnoticed Honey Bee Apis mellifera.

A plant that occurs here in abundance but is not seen at the Balancing Lake: Hemp-agrimony Eupatorium cannabinum.
