New flowers for the year:
*Convolvulus sp. probably Field Bindweed Convolvulus arvensis
A Red Mason Bee Osmia bicornis. Late in its flight period and most of the rufous hairs have been worn away.
An ichneumon wasp. There are so many to choose from and most are not illustrated anywhere. This one was small – that is a (well--chewed) buttercup petal it is resting on.
The pale marks between the segments of the abdomen (tergites) indicate this is a Stripe-faced Dronefly Eristalis nemorum.
The very distinctive Blotch-winged Hoverfly Leucozona lucorum. The Obsidentify name of Blotch-winged Whitebelt is even more descriptive.
Another Bumblebee Plume-horned Hoverfly Volucella bombylans and as with all the others I have seen this year, of the form plumata with the white tail.
With the sun at just the right angle shining through the hoverfly's wings there is no mistaking an Orange-belted Leaf Licker Xylota segnis.
A male Azure Damselfly Coenagrion puella with wings spread exposing the abdomen markings. Note the shape of the marking on the first obvious segment – a "U"-shaped mark.
Remember that small all-black fly with a dark mark in the wing. Well that was a male Black Snipefly Chrysopilus cristatus. This is the very different female with extensive pale in the body and a very different head shape because, as with most fly species, the eyes of females are well-separated rather than co-joined as in most males.
This is a long-legged fly of the Dolichopus genus but I can be no more specific. NatureSpot notes there are 17 species in their home county of Leicester and a very few can be identified from photos.
A cluster fly Pollenia sp. Obsidentify says "unknown" cluster fly but I suspect they mean "unidentified". I am sure it is not new to science.
My first pupa of a Harlequin Ladybird Harmonia axyridis this year. Judging by the very large number of larvae that are present it will not be my last.
The first flower this year of a Convolvulus sp. probably Field Bindweed Convolvulus arvensis. In the past I have been confused about which species this is so I thought Obsidentify would help. "Hedgehog" was its first attempt. After I edited the photo "possible Hoof Fungus". I think not!

In the Priorslee Avenue tunnel:
A Common Marbled Carpet moth Chloroclysta truncata. This is a very variable species. There is another similarly variable if much less common species but luckily that does not have a rufous form.
The best I can do in identifying this moth is to say it is one of the Minor species in the genus Oligia. Recent work has demonstrated that examination of the genitalia is the only way of separating the five adult species contradicting many earlier suggestions that there were some consistent variations in the markings.

The Flash: 06:10 – 07:20
(134th visit of the year)
Bird notes:
- once again the pen Mute Swan was on her own with the lone cygnet. The other four adults seemed to be forming two pairs, albeit loosely. There was no sign of an obvious partner for the pen.
- no Mallard ducklings seen.
- a lone drake Tufted Duck was a new arrival
- still two Great Crested Grebes. Again they did not seem interested in the nest site.
- I think we can say the Reed Warbler has moved on.
Bird(s) noted flying over here:
- 4 Jackdaws
Noted on / around the water:
- 132 Canada Geese
- 21 Greylag Geese
- 1 mainly white feral goose

- 1 (1♂) Tufted Duck
- 6 Moorhens again
- 24 + 4 (2 broods) Coots

Hirundines etc. noted:
- 6 Swifts
- 4 House Martins
Warblers recorded (the figure in brackets is birds noted singing):
- 4 (4) Chiffchaffs
- 1 (1) Blackcaps
Noted around the area:
*Convolvulus sp. probably Field Bindweed Convolvulus arvensis
Another clear, if breezy, start to the day.
A Silver-ground Carpet moth Xanthorhoe montanata with its wings raised to show the abdomen.
It is some weeks since I noted my previous Honey Bee Apis mellifera
A Red Mason Bee Osmia bicornis. Late in its flight period and most of the rufous hairs have been worn away.
This is a sawfly of the Tenthredo arcuata / brevicornis / notha / schaefferi complex. I have read the text for each of these on the very detailed descriptions on the "sawflies.org.uk" web site and am none the wiser!
Another that may or may not be of the same species.
Another Bumblebee Plume-horned Hoverfly Volucella bombylans and as with all the others I have seen this year, of the form plumata with the white tail.
My best photo to date of the lacewing Chrysopa perla.
A rare daytime view of a male plumed midge Chironomus plumosus.
This is a long-legged fly of the Dolichopus genus but I can be no more specific. NatureSpot notes there are 17 species in their home county of Leicester and a very few can be identified from photos.
I wish I knew. This fly looks to be easy to identify but isn't.
The most common and most easily identified of the dagger flies is this Empis tessellata.
A cluster fly Pollenia sp. Obsidentify says "unknown" cluster fly but I suspect they mean "unidentified". I am sure it is not new to science.
