Well this won't win prizes. I had one chance at this male Holly Blue butterfly (Celastrina argiolus) before it flew off to who knows where. Only males show the black wing borders. A not infallible way of separating Holly and Common Blue butterflies in flight is that Common Blues rarely fly above shoulder height

At dawn I found this moth. I am fairly certain it is a Large Long-horn (Nematopogon swammerdamella). There are similar species but with the antennae more than twice the length of the wing this should clinch the identity. Not a moth I have ever noted before.

Amazingly this is my first Honey Bee (Apis mellifera) of the year. It was on Hawthorn just outside Simon's garden so perhaps it is one of his bees.

Two insects here. The larger is a species of mason wasp. There are several similar species though studying the photos on Steven Falk's Flickr gallery suggests only male Early Mason Wasp (Ancistrocerus nigricornis) fits the bill with five yellow bands towards the base of the abdomen. The smaller insect looks to be a Yellow Swarming Fly (Thaumatomyia notata).

This is a young male Blue-tailed Damselfly (Ischnura elegans) with the thorax and anti-humeral stripe green rather than blue (as it will become in a few days).

Probably my best-ever photo of a Marmalade Hoverfly (Episyrphus balteatus).

This is annoying. At last I have photographed a female of the Syrphus (S. ribesii / S. vitripennis) pair. However I can't see either hind leg, the colour of which is the distinguishing feature between these two species.

A fly that for some reason or other I failed to identify yesterday. It is the dagger fly Empis tessellata recognisable by the striped thorax and red-brown wings. I did check this group yesterday but was under the impression that they were not hairy. It was Martin Adlam who, again, put me back on the right track.

 Another for good measure.

Just a few of the many Grouse Wing caddis fly (Mystacides longicornis) that were dancing over the vegetation at the edge of the lake. The long antennae are just about visible on the middle two.

A female cranefly, probably Tipula lunata.

Sometimes known as the Common Crane-fly this is Tipula oleracea recognisable by the dark line down the centre of the abdomen. Also a female with an ovipositor at the tip of her abdomen.

Don't you just love them? Well I do. Yellow Dung Flies (Scathophaga stercoraria) are so gross they are attractive.

 There has to be at least one unidentified fly every day. This is one.

Probably a Common Green Capsid bug (Lygocoris pabulinus). It ran away before I could improve on this photo.

As I walked past a nettle bed dozens of midges scattered and this one flew in to the web of a stretch spider Tetragnatha sp. The spider rushed out and grabbed it.

Probably the last thing the midge remembers seeing!

My first flowers of Blue Flag Iris (Iris versicolor) this year. Apparently all blue irises are horticultural escapes and should really be categorised as Iris sp. as they are cultivars of the real thing.

- As at the main lake Blackcaps seemed to be everywhere this morning.

Birds noted flying over here:
- 1 Lesser Black-backed Gull

Proud(?) parents with their single Canada gosling.

Well it was a long way away! A record shot of the drake Shoveler. A most unusual date to see this species in the Midlands.

A spotty juvenile Robin in characteristic pose. Until it moults and gets a red breast it is safe from attack by territorial adults.

What you again. Loud...

...louder...

...loudest. Now let's see...

...what did you have for breakfast?
