8.0°C > 12.0°C: Intermittent mostly light rain until c.06:30. Stayed mostly cloudy at medium-high level before clearing somewhat from the W after 08:15, still with plenty of cloud about. Light W wind throughout. Very good visibility.

Priorslee Lake: 04:45 – 05:55 // 06:45 – 09:40
(126th visit of the year)
Bird notes:
- The resident pair of Canada Geese and their well-grown gosling were present throughout. When I arrived there were eight more adults together on the water. Another four flew in and stayed for a while. All these 12 had gone by 06:55. After 09:00 yet another five flew in. The cob Mute Swan seemed rather sanguine about these, less so when three Greylag Geese dropped in.
- Another one of the Mute Swan cygnets has gone missing. Just six now.
- At least 50 Swifts were overhead at 05:15, some very high up. By 07:15 I estimated no more than 30 though later numbers built again until over 75 in the area by 09:00.
- Mostly rather fewer warblers were noted braving the wet conditions. Exceptions were:
- a very noisy second singing Sedge Warbler in the SE area was new. An addition to the long-term songster along the S side.
- after a number of days of "was that really a Common Whitethroat I heard briefly" a trio was seen sneaking around behind the sailing club shelter. No song heard, just a few scolding churrs.

New flowers for the year noted:
Definitely the find of the day for me was this tiny micro-moth, a Common Slender (Gracillaria syringella). Just 7mm long (about a quarter of an inch for us oldies). I saw this in flight and managed to spot where it landed. I have inverted the image for easier viewing. My literature describes this species as very common but it must be very easy to overlook. A new species of moth for me.
Sharing the same lamp pole was this very easy to identify Brimstone Moth (Opisthograptis luteolata). I will probably see several more of these, unlike the carpet moth which whilst just about annual is usually a one-off.
The general scruffy appearance is a good clue that this is an Early Bumblebee (Bombus pratorum). The identity is confirmed by three areas of buff / orange, though on this specimen the midriff band is hardly apparent.
With the yellow markings wrapping around the side of the abdomen this has to be a Migrant Field Syrph, also known as Migrant Hoverfly (Eupeodes corollae). The 'migrant' epithet is not entirely appropriate as this species is not exclusively a migrant from Europe and neither is it the only species whose numbers are boosted in such a way.
One day I will find one of these Orange-belted Leafwalker hoverflies (Xylota segnis) with its wings open...
"A rotund blue-black beetle" is about all I can tell you here apart from it being another insect that seems to like buttercups.
This ladybird is a 24 Spot Ladybird with the scientific name – take a deep breath – Subcoccinella vigintiquattuorpunctata. The pattern of spots somewhat resembles one form of the Harlequin Ladybird (Harmonia axyridis) but the head lacks the bright white patches of the latter species. It is also very small. The number of spots is variable on both species.
The crab spider Misumena vatia with its legs in the correct orientation unlike the one I photographed yesterday.
The Flash: 06:00 – 06:40
Between the lake and The Flash:
- Moorhens calling at both pools. Investigation of alarm calls from the upper pool flushed...
- 1 Grey Heron
- 1 Chiffchaff singing, today back on a favourite song-post atop a dead tree alongside the lower pool.
In the Priorslee Avenue tunnel:
- The Small Tortoiseshell (Aglais urticae) chrysalis again.
- *1 Common Swift moth (Hepialus lupulinus) on the roof.
- 1 Tetragnatha sp. stretch spider
Another moth photo I have inverted for easier viewing. This is a Common Swift (Hepialus lupulinus). It was on the roof of the tunnel. A common moth last seen by me in the area in very early June in both 2018 and 2019.
None
Another new moth for the year is this Dark-barred Twin-spot Carpet moth (Xanthorhoe ferrugata) on a lamp pole pre-dawn despite the rain.
I have not seen one of these Common Green Lacewings (Chrysoperia carnea) for several weeks.
These Broad-striped Rhogogaster sawflies (Rhogogaster scalaris) seem very common at the moment.
This is probably the same species of green-eyed and hairy fly that I photographed yesterday. But...
...from another angle the eyes seem to be red. Note the thick basal part of the antennae. A bit more research on the web leads me to the conclusion that it is one of the Dolichopus species which, as so often, cannot be specifically identified from photographs.
To get and idea as to its size here it is wandering up toward the life-line on the palm of my hand.
I found another of these Hairy Shieldbugs or Sloe Bugs (Dolycoris baccarum) today.

(122nd visit of the year)
Bird notes:
- A Canada Goose was sitting on the Derwent Drive footpath brooding at least three goslings in the rain at 06:05. I did not wish to disturb it so the exact number of goslings is unknown. Later they had been moved by dog-walkers but I could not see where to.
- The potential love-affair between the 2019 Mute Swan and one of the 2021 birds seems to be over. The two 2021 siblings are now very much staying together and keeping apart from the 2019 bird. I was informed that there had been a report (on Facebook?) of a fourth Mute Swan yesterday.
- No juvenile Moorhens located.
Birds noted flying over here:
- 1 Jackdaw
Hirundines etc. noted:
None

Elsewhere:
Nothing of note
