Priorslee Balancing Lake and The Flash

7.0°C > 15.0°C: A mixed bag. Mainly clear start. Clouded after 07:15 with a very light shower c.08:30. The skies cleared after 09:00. Light mainly easterly breeze. Very good visibility.

Sunrise: 04:59 BST

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

Priorslee Balancing Lake: 05:10 – 06:20 // 07:25 – 09:45

(112th visit of the year)

Bird notes:
- *an Oystercatcher was an unexpected visitor. It flew in from the East to the south-west grass at 05:50 and left to the West at 05:55.
- a Lesser Whitethroat was singing in the south-west wooded area at 09:00. I heard (and saw) it in the same area a month ago and this raises the possibility that it paired and bred here and is singing again to re-establish its territory and pair bond between broods. Of course it could as well be a bird that has failed a breeding attempt elsewhere and setting up a new territory.

More or less sunrise.

And looking the other way for a change, up the concrete ramp with the new fencing in full view.

The Oystercatcher that dropped in for a few minutes.

And off he goes. I say 'he' because it was calling loudly but thinking about they all seem to be noisy so perhaps females call loudly as well.

My first Common Blue butterfly Polyommatus icarus of the year. A male.

This is a Bramble Sawfly Arge cyanocrocea.

The red on the thorax identify this as an Alder Sawfly Eriocampa ovata.

Yes well. A black ant Lasius sp. is about as far as I can go with this. It was apparently on its own – a scout?

This is a Common Dronefly Eristalis tenax. Not very east to separate from Tapered Dronefly E. pertinax from this angle.

Easy from this angle when the dark front legs identify it. Tapered Dronefly has extensively pale front legs.

This had me perplexed. It seems it is 'just' a Tiger Hoverfly Helophilus pendulus but was about two-thirds the usual size.

Not a bumblebee: it cannot be a bee as it has short antennae. It is a Bumblebee Plume-horned Hoverfly Volucella bombylans. The plume 'horns' (antennae) are just about visible.

Struggling out of its larva case is what I believe will turn in to a Common Blue Damselfly Enallagma cyathigerum.

A Red-eyed Damselfly Erythromma najas. I have noted very many more of this species this year and also seen them in many different places around the water.

The third of this morning's trio of damselfly species: a Blue-tailed Damselfly Ischnura elegans.

Two plumed midges on the ID label of one of the street lamps. They are somewhat dew covered but they seem to be different species of males. One has dark marks in its wings and the head shapes look different. No idea about their identity.

A very smart fly. It is a Muscid fly Graphomya maculata . It can be identified as a female both by the eyes being well separated and the lack of the males orange markings on its abdomen. As far as I can tell this is a new (newly recognised?) species for me.

The only caddis fly I find easy to identify is this Grouse Wing caddis fly Mystacides longicornis with the patterned body and long antennae. There is a form with an unmarked body!

A better photo of a cranefly Nephrotoma quadrifaria than the one I took of a specimen on a street lamp pole yesterday morning. Very smart.

A soldier beetle Cantharis nigricans.

A female Swollen-thighed Beetle Oedemera nobilis. Unusually, so far this year, I have seen more females than males.

Superficially like a Nettle Weevil Phyllobius pomaceus but with a much shorter 'snout'. The dark tips to the antennae identify it as Polydrusus formosus. Another new species for me.

A wolf spider Pardosa sp. With 'boxing glove' palps this must be a male.

Not sure what to make of these three apparently dead flies. There seemed to be no spider around and none of the flies looks to have been eaten.

The Flash: 06:25 – 07:20

(115th visit of the year)

Bird notes:
- there seems to be the beginnings of a build-up of the geese ahead of their post-breeding wing-moult when they become flightless for several weeks.
- that said one of the 'juvenile' Mute Swans chased nine of the Canada Geese away.

Bird(s) noted flying over here:
None

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

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

Noted on / around the water:
- 42 Canada Geese
- 1 Canada x Greylag Goose
- 3 Greylag Geese
- 9 + 3 (1 brood) Mute Swans
- 17 (13♂) Mallard
- 4 (2♂) Tufted Duck
- 6 + 2 (1 brood) Moorhens
- 17 + 9 (6 broods) Coots
- 1 Great Crested Grebe

Noted elsewhere around The Flash:

Moths:
- 1 Common Pug Eupithecia vulgata
- *1 White-pinion Spotted Lomographa bimaculata
- *1 !!Marbled White Spot Protodeltote pygarga : ** a new species for my Shropshire list

Hoverflies:
- 1 Chequered Hoverfly Melanostoma scalare [Long-winged Duskyface]

Other flies:
- *1 caddisfly Tinodes waeneri

Beetles:
- many Alder Leaf Beetles Agelastica alni

Other things:
- *1 Common European Earwig Forficula dentata

Spiders:
- Long-jawed Orb-web Spiders Tetragnatha sp.

A juvenile Wood Pigeon. Juveniles lack the white neck patch of the adult or the glossy purple / green patch shown by the slightly smaller Stock Dove. They share with the adult the white on the leading edge of the folded wing.

Trying to look like a rose petal is a White-pinion Spotted moth Lomographa bimaculata. My first at this site.

I was trying to get a photo of the female Common European Earwig Forficula dentata below white I thought was a bird dropping but not so.

The 'bird dropping' revealed itself as a Marbled White Spot moth Protodeltote pygarga, my first in Shropshire.

A caddisfly Tinodes waeneri.
