The smell from the abundant Blackthorn was great, and there was plenty going on around the blooms. I failed to successfully point the camera at a few hoverflies, flies and bees but I managed to get these:
I'm pretty sure this is Andrena flavipes - Yellow-legged Mining Bee
Plenty going on around the gorse too, with abundant ladybirds and Gorse Weevils, plus a fair few shieldbugs.
Sloe Bug / Hairy Shieldbug
Around the pool I had a bit of poke around the reedmace heads, finding larvae of Limnaecia phragmitella in the process along with a couple of Water Ladybirds and Bulrush Bugs.
I decided to collect a fallen stem, cut into foot-long sections so I could fit it in my bag. When I got home I had a poke about in the stem and found a few more bits.
Think this is also Limnaecia phragmitella, though actually in the stem-sheath.
