Don't really have a clue what this is but do have diving beetle in the pond. If I close my eyes and squint it bears a superficial resemblence to a post by jenny craven on the 9th of June (Perhaps a younger version) http://www.ispot.org.uk/node/161205?nav=latest_observations

I originally thought it may have been a type of diving beetle as I have these in the pond but was really unsure. Having looked at the pics I agree with you. Also one of the identifaction charts for pond surveys on OPAL shows something similar. Its pleasing to have an ID at last

The last two pictures?

The first four pictures are definitely of Dytiscid larvae. However, if you look at the last two pictures they are of a different organism. Look at the shape of the head, the long antennae and the nature of the tails. I think that may be earwig nymphs. Have a look at these links:

The last two pics were taken when I photographed the caddis fly case you previously commented on. They were in the net at the same time. I thought they were a different creature so split the pics and they have ended up here.

They certainly look like earwig nymphs will post them as a seperate sighting.

Discarding caddis and hemiptera etc on appearance.
Some of these Dytscids can get to be pretty massive, colleagues who should know better have tried calling them dragonflies and allsorts.

It's a Dytiscid rather than other beetles partly given the length and shaping of the [tail].

Time flies like an arrow, but fruit flies like a banana.
