Sweet sixteen

I have never seen anything like this.  Several thousand ladybirds, all in one place.  They were clustered on posts supporting a newt fence in Coventry and there were hundreds on each post and dozens of posts.  Most were on the east sides of the posts with a few on the north sides. This is a new species to me, 16-spot Ladybird (Tytthaspis sedecimunctata).

The 16-spot Ladybird is one of only a few vegetarian ladybird species (Orange Ladybird, 22-spot Ladybird and 24-spot Ladybird being others) and feeds on pollen, nectar and fungi.  It is mainly a grassland specialist but is also found in brownfield sites.  It is pretty common and widespread down south but doesn't venture farther north than south Yorkshire, which is a pity as we have plenty of grass up here.

I also saw a couple of 7-spot Ladybirds which show how small the 16-spot Ladybirds are.

And a real bonus, a solitary Adonis Ladybird, only the second one I have seen.
