Note
Note that Severn-Trent contractors will be doing some grass-cutting this week, supervised on-site by one of their environmental scientists. This will hopefully prevent a repetition of the mess the contractors made last Autumn. The plan is to created more species diversity though this will take time and further mowing to discourage the more aggressive plants. I have been in email correspondence over the timing – during "no mow May". I have been given assurances about the sanctity of the orchids.
Bird notes:
- the pair of Canada Geese still with a single gosling
- the pair of Greylag Geese still with just three goslings.
- *a trio of visiting Mute Swans was proving hard for the resident cob to persuade to leave. Usually the cob will fly toward one of visitors and land short but twice at least he pressed home to collide with his target. One of the visitors was a first year bird.
- a pair of Gadwall seen early only flying off East at 05:50. At 09:00 a drake (the same?) was present.
- a duck Mallard with a single duckling again
- the duck Pochard in her usual place.
- yesterday's pair of Tufted Duck not seen.
- no juvenile Great Crested Grebes seen.
- Reed Warblers continue to confuse by singing from 'new' locations. Are these new arrivals or residents moving around? It is crowded in some reedy areas.
- certainly two Garden Warblers singing again but could there have been a third? #2 was still in the south-west area but early only. Yesterday's new(?) bird, #3, was singing in the south-east area, also early only. Then much later there was some very intermittent song from #1 along the South side. Could #1 and #3 be the same? Perhaps he has found a mate who has chosen a slightly different place to nest?
- only one Common Whitethroat singing today: Saturday's new arrival singing almost continually and doing display flights.
- what sounded like a family party of Jays making a lot of noise – as they do – along the North side. Several birds seen, none well-enough to confirm presence of juveniles.

New plants for the year:
*Yorkshire-fog Holcus lanatus [a grass]
Blue Flag Iris Iris versicolor
A Common Carder Bee Bombus pascuorum with its tongue well inside what seems to be the flowers of a "Dog Rose" Rosa canina or similar.
There are about 2500 species of ichneumon wasp in the UK of which about 20 can be identified from photos. This is not one of them. Come back in ten years when the progress of AI means that the equivalent of Obsidentify will take a DNA sample and provide the precise identity.
The first of what I am sure will be many Common Marble moths Celypha lacunana, a species easily flushed from vegetation during daytime.
A Plum Tortrix moth Hedya pruniana. This was my "safety shot" as it landed on the underside of a leaf. Before I could get better positioned it crawled on top of the leaf and out of view.
There were very few hoverflies noted this morning. This is one of three Marmalade Hoverflies Episyrphus balteatus I saw. My reflection is visible in its thorax.
Another doing what I also noted many flies doing today: licking the leaves. Perhaps some residue moisture from the overnight dew?
The only other hoverfly species I saw was this Twin-spot Boxer Platycheirus rosarum, also showing my reflection. You cannot see the two spots on the abdomen with the wings closed. Obsidentify calls it Fourspot Sedgesitter and indeed some specimens do show a feint second pair of spots. I have no idea why it uses the scientific name Pyrophaena rosarum. Note it appears to be laying an egg(?)...
Even though the wings are unusually plain this has to be a Grouse Wing caddis fly Mystacides longicornis. Not easy to see but the antennae reaches the left edge of the photo eliminating any other species..
A Cucumber Green Orb Spider Araniella sp., either A. cucurbitina or A. opisthographa not separable from photos. Note the six eyes. Some spiders have six: most have eight.
This tiny spider on the boxing rink is apparently the Long-jawed Orb-web Spider Pachygnatha degeeri. New for me.
A Blue Flag Iris Iris versicolor. I read that all these in the UK originate from gardens and while freely breeding and spreading they are "not native". But then what is? There were no plants during the Ice Age!

Bird notes:
- a single well-developed Mallard duckling was seen again

The sunrise looking threatening.
Better soon after!
Two of the trio of visiting Mute Swans splash down.
On the face of it there does not seem to be much pollen left in the almost finished flower of what was probably Ribwort Plantain Plantago lanceolata.
A Common Carder Bee Bombus pascuorum with its tongue well inside what seems to be the flowers of a "Dog Rose" Rosa canina or similar.
This Blackthorn Tip Moth Argyresthia spinosella is a new species for me.
The first of what I am sure will be many Common Marble moths Celypha lacunana, a species easily flushed from vegetation during daytime.
Trying to fide in the grass was this Common Nettle-tap moth Anthophila fabriciana. My second this year.
A straw-coloured moth with dots in the forewings. Must be a Straw Dot Rivula sericealis.
The only other hoverfly species I saw was this Twin-spot Boxer Platycheirus rosarum, also showing my reflection. You cannot see the two spots on the abdomen with the wings closed. Obsidentify calls it Fourspot Sedgesitter and indeed some specimens do show a feint second pair of spots. I have no idea why it uses the scientific name Pyrophaena rosarum. Note it appears to be laying an egg(?)...
..."Bombs away!" It is now rolling down the grass stem.
A female Yellow Dung Fly Scathophaga stercoraria asking to leave the room...
...and a male. Much more yellow-toned.
Another female. I think this species is attractively ugly – if that makes any sense.
A Cucumber Green Orb Spider Araniella sp., either A. cucurbitina or A. opisthographa not separable from photos. Note the six eyes. Some spiders have six: most have eight.
About the only species of grass I can easily identify is Yorkshire-fog Holcus lanatus.

A scruff-looking Treecreeper shinning up a tree. Not sure whether it is an adult care-worn from family duties or a fluffy youngster.
Snoozing in the crevice of street lamp pole I found this male Spotted Meliscaeva hoverfly Meliscaeva auricollis.

A caddis fly is about all I can say here.
