Bird notes:
- the Mute Swans do have only a single cygnet.
- seven Great Crested Grebes were present when I arrived: another bird flew in.

It is unusual for Blackcaps to sing in the open once all the leaves are on the trees.

He is probably between broods and proclaiming his territory.

A Common Marble moth Celypha lacunana.

A caterpillar of a Drinker moth Euthrix potatoria. I recorded one here last year on 30 May.

Perhaps this one wants its tummy scratched. I did not oblige – with all those irritant hairs.

A while since I saw one of these Tree Bumblebees Bombus hypnorum.

And another.

A Downlooker Snipefly Rhagio scolopaceus looking the wrong way.

Wonderful ugly fly #1. No time to research them today I am afraid.

 And #2.

A Harlequin Ladybird Harmonia axyridis of the form spectabilis.

This one of the form succinea.

Some are more orange and on some the spots can be faded almost away. This is both. The white on the face is consistent.

This is a nymph of a plant bug, probably Deraeocoris flavilinea though many nymphs look similar.

At the top a spider Dictyna sp. Seems to have taken on a fly much larger.

The Long-jawed Orb-web Spider Tetragnatha sp. I found on one of the street lamp poles around dawn. A male with large palps.

New flower today. This is Snowberry Symphoricarpos sp. probably S. albus.

A Brimstone Moth Opisthograptis luteolata.

This seems to be a Buff-tailed Bumblebee Bombus terrestris though I cannot explain why it has two pale bands at the tip of its abdomen.

When you get close to a Common Wasp Paravespula vulgaris you realise how hairy they are.

When I first saw this hoverfly it was resting on a leaf with its wings closed obscuring the markings. Luckily it went for a hover, revealing it as a Grey-spotted Boxer Platycheirus albimanus.

Another view.

This Common Blue Damselfly Enallagma cyathigerum was asleep on a street lamp pole in squirrel alley. Odd.

Next to the damselfly was this caddisfly Tinodes waeneri.

A Common Nettle Bug Liocoris tripustulatus
