Not sitting at a helpful angle on a street lamp pole was this Drinker moth Euthrix potatoria. I previously noted caterpillars crossing the path this year.
A typically scruffy-looking Common Carder Bee Bombus pascuorum
A very worn Early Bumblebee Bombus pratorum. Just look at the battered edges to the wings. Much of the body hair has worn away and faded and it was a challenge to identify it.
Against a grass seed-head the small size of a Chequered Hoverfly Melanostoma scalare can be appreciated.
An unusual angle showing the abdomen and confirming that this is a male with the square yellow markings. The female has triangular yellow markings.
The bright yellow scutellum (the half moon-shaped area behind the thorax) is the best clue that this small hoverfly is a Common Twist-tail Sphaerophoria scripta.
A very common hoverfly at the present: it is a Pellucid Fly Volucella pellucens.
A male semaphore fly Poecilobothrus nobilitatus. Note how the eyes appear two-toned: red or green depending on the angle of the light.
There was the usual array of flies that I have neither the time nor the inclination to research when they occur in profusion. Here is #1.
And a particularly hairy #2.
"All the better to see you with". Fly species #3.
Here is #4.
Another: #5.
Now #6
Last one and another hairy one: #7.
I know this greenbottle is a Lucilia sp. but I cannot say which.
A tiny creature, It is most likely the nymph of a Red Bug Deraeocoris ruber. Many bug nymphs are very similar but the red bug is by far the most common plant bug.
A Common Froghopper Philaenus spumarius. This species emerges from the cuckoo-spit – the white frothy liquid secreted by the nymphs of these sap-sucking bugs. The adults are very variable in markings. When threatened the froghoppers can jump two feet high with an acceleration of 400g! Difficult to catch - which is the idea.

In the Priorslee Avenue tunnel:
Moths:
- 1 !Single-dotted Wave Idaea dimidiata
- 1 !Single-dotted Wave Idaea dimidiata
Molluscs:
- 1 (Common) Striped Woodlouse Philoscia muscorum
- 1 (Common) Striped Woodlouse Philoscia muscorum
I found my first Single-dotted Wave moth Idaea dimidiata on the wall of the tunnel. They seem to like this location: I saw many there last year.

The Flash: 06:15 – 07:05
(144th visit of the year)
Bird notes:
- another increase in Mallard numbers.
- where have many of the increased number of Coots come from? There were about 14 nest sites so that means 28 adults. I have not noted 14 juveniles progressing to the stage where they are, even at some distance, indistinguishable from adults though I did not note any juveniles today.
Bird(s) noted flying over here:
- 1 Common Buzzard
- 7 Jackdaws
Hirundines etc. noted:
- 2 Swifts
- 7 House Martins
Warblers noted (the figure in brackets relates to birds heard singing):
- 6 (5) Chiffchaffs
- 4 (4) Blackcaps
'nominal' warbler:
- 1 (1) Goldcrest
Noted on / around the water:
- 203 Canada Geese
- 67 Greylag Geese
- 1 Canada x Greylag Goose
- 3 + 3 (1 brood) Mute Swan
- 47 + 5 (1 brood) Mallard
- 17 (14♂) Tufted Duck
- 4 + 1 (1 brood) Moorhens
- 42 Coots
- 4 Great Crested Grebes
Noted elsewhere around The Flash:
Moths:
- 1 !!Gold Swift Phymatopus hecta
- 1 Tawny Grey Eudonia lacustrata
- 1 !Light Emerald Campaea margaritaria
- 1 !!Gold Swift Phymatopus hecta
- 1 Tawny Grey Eudonia lacustrata
- 1 !Light Emerald Campaea margaritaria
Shieldbug
- 1 Hawthorn Shieldbug Acanthosoma haemorrhoidale
- 1 Hawthorn Shieldbug Acanthosoma haemorrhoidale
Yet another new brood of Mallard. A group of five. But how many will survive?
The Coots are amassing on the edge of island. Why? How can I get an accurate count when they are so jammed together? And which of them are full-grown juveniles with slightly smaller white shields?
A moulting Common Buzzard flies over. This species has been nowhere near as common this year at the times I visit.
Moth find of the morning. This is a Gold Swift Phymatopus hecta and a new moth for me.
Another moth new for the year. I usually find on of these Light Emerald moths Campaea margaritaria somewhere in the area.
Among all the debris from spiders' meals I noted this Hawthorn Shieldbug Acanthosoma haemorrhoidale.
