Roydon Common
Heath Sandwasp (Amophila pubescens) with prey.
A southern UK species with outlying sites in North Norfolk.
Just that little bit smaller than its near relative the Red-banded SandWasp (Ammophila sabulosa)
This caterpillar was just too heavy for her to fly with but she wasn't going to give it up.
She carried it over the sand with various twists and turns for a
good eighty feet. (and that was the bit I saw.)
The burrow was already prepared and she quickly ducked in almost spat out this bit of brushwood plugging the hole.
She then dragged the caterpillar into the burrow backwards.
Then she set about filling up the burrow. 
Bit of packing down
Then brushwood
Really packing it down.
The stalked third submarginal cell on the forewing
More packing down
More brushwood
Then backwards scrabbling of sand into the hole
Packing down
More scrabbling of sand
Levelling off
So finally nothing can be seen of the burrow
Beetle Sp
Rose Chafer perhaps?
It is difficult to convey in a photograph the complexity of nest burrows in the sand on the path that crosses the reserve.
In the area below the sand flash on the track there are so many small burrows.
You can see some are freshly open by the darker moist soil humps.
There are just so many packed into such a small area. On the sand flash itself the surface is so disturbed from where
people have been playing on the sand you wonder how the colony manages to cope.
But they do.
And all the while a few inches above the surface there is the constant criss crossing of bees flying.
Whether anyone could write an algorithm to explain the flight pattern is open to question.
Largely the males, presumably, hoping for mating opportunities The females do seem to make themselves available in slight open depressions in the sand and then there is a convergence of males until one takes hold.
But it doesn't take long, although occasionally the female flies off as if not convinced.
The tussle on the ground begins between the pair (I wonder whether ecstatic tussle would be a better explanation. There is certainly a lot of waving of the females legs in this species)
And the other males fly off in myriad of directions.
In amongst all this the orange of their Nomad can be seen dropping onto possible nests ripe for predation.

♂︎
They have a very frenzied mating.
Afterwards it looks as though both sexes can often be a little disoriented.
The females sit a while before flying off.
The males can be seen skittering about on the ground or having trouble negotiating stones or grass stems.
But then again there can also be very quick attempts at mating as a female is quickly disappearing in her burrow.
Whether these are successful or not….?
And again the most amazing things are the females ability to find their nests in the sand when the surface is so disturbed, coupled with the speed they disappear into the burrows.
Head down and within seconds she has disappeared

Small Sandpit Mining Bee (Andrena argentata)
The Small Sandpit Mining Bee has cuckoo bee that predates its nests. 
Said Cuckoo found a nest to predate.
She was underground for about twenty minutes
and
then
she reappeared
But she didn't fly off straightaway
After a bit of reorientation presumably
She set to and thoroughly cleaned herself off.
Eyes
Antennae
Mandible
Antennae and top of the head
Almost done
One final go at the left eye before flying off
I guess because they don't do all the excavating it's a bit more of a trial for them to go underground.
The host bees themselves are so much quicker at going in and out.

Potter Spider Wasp (Auplopus carbonarius ?)
On reflection if you look at the wing venation visible on this specimen.
Stephen Falk comments that the closed cells of the
forewing extend much further towards the wing tip
in the case of Auplopus carbonarius
In this case the closed cells are much further away from the wing tip.

Anoplius Sp
There are three all black British Anoplopius pompilid (Spider hunters) Sp
Anoplopus nigerrimus, Anoplius caviventris & Anoplopius concinnus
Anoplius niggerimus is one of the commonest pompilids
In this case the third sub marginal cell is petiolated ie. it joins one edge of the second submarginal cell
to create a more triangular cell rather than join the marginal cell vein
This is diagnostic for male & female

Pompilid Wasp Sp?
Bristle-tailed Spider Wasp (Anoplius infuscatus)? on Wild Carrot (Daucus carotta)
You can see black bristley hairs at the tip of the abdomen in the last image. Matt body.
And the wing pattern seems to fit.
Still open?
