Priorslee Balancing Lake and The Flash

15.0°C > 18.0°C: Low overcast. Spell of drizzle after 07:45. Beginning to lift as I was leaving. Moderate south-westerly wind. Moderate visibility, poor in drizzle

Sunrise: 05:18 BST

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

Priorslee Balancing Lake: 05:00 – 06:15 // 07:00 – 09:25

(160th visit of the year)

Severn Trent contractors have mown an area of the long grass as part of a regime to try and improve the plant species diversity by allowing light to reach the ground. Another cut is planned in a few weeks. The mowings are to be gathered in to heaps. It is apparently too expensive to pay the contractors to take the grass-cuttings away.

Bird Notes

New Bird Species
Best today was a Linnet flying East at c.07:10. Surprisingly this is the first I have recorded here this year and bring my 2024 site bird list to 98.

Other bird notes:
- I still cannot work out which pair of Mute Swans is doing the chasing.
- A well-grown Mallard duckling seen. I probably overlooked it yesterday and would have done so today had it not scrambled ashore showing its stubby wings as it kept its balance.

Counts of birds noted flying over:
- 42 Canada Geese: outbound in six groups
- 1 Greylag Goose: outbound

Noted on the street lamps poles pre-dawn:

Spiders etc.:
- *Bridge Orb-web Spider Larinioides sclopetarius
- *several Noble False Widow Steatoda nobilis
- *other unidentified spiders

Other things
- *1 Common European Earwig Forficula dentata: dead?

Noted later:
The only insects of note were two different female horseflies that were biting me. Neither identified as both deceased. I have only ever logged one horsefly here previously. That was a male.

Butterflies:
- none

Moths:
- *Horse-chestnut Leaf-miner Cameraria ohridella

Bees, wasps etc.:
- Garden Bumblebee Bombus hortorum

Hoverflies:
The first name is that used by Stephen Falk. The name in square brackets is that given by Obsidentify or other sources if different. Scientific names are normally common. The species are presented in alphabetic order of those scientific names.
- *Chequered Hoverfly Melanostoma scalare [Long-winged Duskyface]

Damsel-/dragon-flies:
- none

Other flies:
- *Little Snipe Fly Chrysopilus asiliformis
- *otherwise only unidentified flies noted

Bugs etc.:
- none

Beetles:
- none

Molluscs:
- White-lipped Snail Cepaea hortensis

Spiders etc.:
- none

New flowers noted:
- none

As best I could shooting against the leaden sky. One of a party of Long-tailed Tits.

Not any better I am afraid.

Same with this Chiffchaff!

To illustrate the size of Horse-chestnut Leaf-miner moths Cameraria ohridella one is dead-centre of the photo amongst the remnants of severely chewed Horse-chestnut leaf.

 The tiny moth kindly stayed put and allowed me to take this close-up photo. An attractive moth behaving slightly less manically in the dull weather – usually several are flying around and around and never seem to land in view.

The only hoverfly I noted was this Chequered Hoverfly Melanostoma scalare here sitting on one petal of a Greater Bindweed flowers Convolvulus sylvaticus.

The green eyes and dark wing cloud identify this small fly as a Little Snipe Fly Chrysopilus asiliformis.

Strangely all the flies I noted were small flies seeming at risk of annihilation by rain drops. An unidentified fly sits on a grass stem surrounded by water droplets.

A collection of spiders lurking at the top of a street lamp at dawn. I do not have a solid identity for any of them. The species with its web (egg sac?) was suggested as a salt-water spider crab by Obsidentify. The lower right spider with a white band around the edge of the abdomen is likely a Noble False Widow Steatoda nobilis.

And another collection of spiders on another street lamp. One of them seems to have successfully trapped a Common European Earwig Forficula dentata. The spider bottom left looks to be a Bridge Orb-web Spider Larinioides sclopetarius.

In the Priorslee Avenue tunnel:

Moths:
- *!1 Dingy Dowd Blastobasis adustella

Other things:
- 4 White-legged Snake Millipede Tachypodoiulus niger

This is a Dingy Dowd moth Blastobasis adustella, a species I see most years. The pale shoulders and inverted pale 'V' mark are the best identification marks.

The Flash: 06:20 – 06:55

(163rd visit of the year)

Bird notes:
- most of the geese have found and are using their new wings.
- probably an incomplete count of the Coots: the birds standing on the edge of the island were had to discern in the poor light.

Bird(s) noted flying over here:
None

Hirundines etc. noted:
- 3 House Martins

Warblers noted (the figure in brackets relates to birds heard singing):
- 6 (1) Chiffchaffs
- no Blackcaps
'nominal' warbler:
- no Goldcrests

- 14 Greylag Geese
- no Canada x Greylag Goose
- 2 + 3 (1 brood) Mute Swan
- 19 (?♂) Mallard
- 26 (?♂) Tufted Duck

Beetles:
- Alder Leaf Beetle Agelastica alni: larva

Spiders etc.:
- 2 harvestmen Dicranopalpus ramosus/caudatus

The Swallow Prominent moth Pheosia tremula had moved slightly allowing me to get a side-on view to better show the 'prominent' where the wing-tips meet.
