No sunrise today.

The Common Kestrel that flew over: not certain as to the sex. This was a silhouette against a leaden sky and the photo editor has done a good job to show this much detail.

Two Plain Pollen-moths Micropterix calthella on their obligate food plant – buttercups.

One of two Common Nettle-tap moths Anthophila fabriciana this morning.

A Common Marble moth Celypha lacunana.

My second Plum Tortrix moth Hedya pruniana of the year.

It looks as if this Chequered Hoverfly Melanostoma scalare needs to go on a diet.

One of only two damselflies I noted, both motionless. This is a Blue-tailed Damselfly Ischnura elegans.

Sadly this cranefly flew off before I could get a better angle and photo. The overall colour suggests it must be Phylidorea ferruginea.

As usual many unidentified flies. Here are a few I cannot recall showing previously and which I have not had time to research. #1.

#2.

#3.

 #4.

My find of the morning was this Wasp Beetle Clytus arietis. I see one most years.

A 7 Spot Ladybird Coccinella 7-punctata with its spots somewhat faded.

My first 14 Spot Ladybird Propylea quattuordecimpunctata of the year showing the face.

And here you can count all the spots. "Spots" is a bit of a misnomer!

One of about ten unidentified slugs responding to the overnight rain.

The distinctive abdomen shape of a Stout Sac Spider Clubiona sp.

A Bridge Orb-web Spider Larinioides sclopetarius, a species that frequents the street lamps at the West end and which is more usual in the Winter period.

A small, attractively marked spider is about all I can say!

In the Priorslee Avenue tunnel:

Flies
*$ 1 cranefly Ilisia occoecata
*$ 1 cranefly, possibly Rhipidia maculata
*1 cranefly Tipula oleracea
5 owl midges Psychodidae sp. [Drain Fly, Moth Fly or Owl Fly] again
*$ 1 midge Psectrotanypus varius
28 other midges of various species.

Arthropods:
1 White-legged Snake Millipede Tachypodoiulus niger

A happy hunting ground for craneflies this morning. This cranefly is Ilisia occoecata.

This cranefly could be Rhipidia maculata – the wing pattern matches though the antennae are not quite right.

The dark line down the centre of the abdomen of this female cranefly identifies it as Tipula oleracea.

The patterned wings identify this small midge as Psectrotanypus varius.

The Flash: 06:30 – 07:25

(125th visit of the year)

Bird notes
Best today was my second Reed Warbler of the year here. It was singing away deep inside the reeds alongside Derwent Drive. There is precedent for such a later arrival - I have had one in June in previous years.

Other bird notes:
- *one of the four visiting Mute Swan (the pen '7JSS') went for a fly-around and probably departed at least for a while. It was presumably the same bird reported by fishermen flying around the Balancing Lake while I was en route back to there.
- an update on the bird noted yesterday with the blue Darvic ring '7JXV'. It has had a colourful life, abandoned as a cygnet with five siblings at Kenley near Much Wenlock in 2022. It was taken in to care by Cuan Wildlife Rescue. It was released near Cosford later that year. Then in October 2023 it was found stranded on the M54 and again Cuan came to the rescue, releasing it back near Cosford a few days later. There has been no sighting since then – until yesterday. Thanks to Martin Grant for the information.
- no Mallard ducklings noted.
- no Tufted Duck noted.
- one Great Crested Grebe heard calling possibly to an unseen bird underneath overhanging vegetation around the island.
- for the last few days I have only heard House Martin(s) above the lake with the Swifts.

Bird(s) noted flying over here:
None

Noted on / around the water:
- 25 Canada Geese
- 2 Greylag Geese
- *6 + 1 (1 brood) Mute Swan: one of these departed
- 14 (11♂) Mallard
- no Tufted Duck
- 8 Moorhens
- 19 + 3 (2 broods) Coots
- 1 Great Crested Grebe

Hirundines etc. noted:
- 6 Swifts
- 1 House Martin: see notes

Warblers recorded (the figure in brackets is birds noted singing):
- 4 (4) Chiffchaffs
- 1 (1) Reed Warbler
- 5 (5) Blackcaps

Noted around the area:

Moths
2 Pale Tussocks Calliteara pudibunda: one for its seventh day; *the other on the adjacent street lamp pole in squirrel alley.

Flies:
*numerous different midges and flies

Spiders, harvestmen etc.:
2 Long-jawed Orb-web Spider Tetragnatha sp.

New flowers for the year
Cleavers Galium aparine

What I assume is the resident pen Mute Swan with the one cygnet. Whichever parent this was the other was well apart and seemingly uninterested,

Mute Swan '7JSS' going for a fly. It is as well that the Darvic ring is on her left leg.

I noted two Song Thrushes in full voice and two others. Here is one of the latter.

And the other, collecting food. I have no idea why the camera has resolved them to have such different tones of brown.

The newly arrived (noticed?) second Pale Tussock moth Calliteara pudibunda in squirrel alley.

An apparently very distinctive fly with a red abdomen. I have not found anything for it.
