First up the bees. The species seen today were: White-tailed, Buff-tailed, Common Carder, Honey and Tree Bumblebee. All these, with the exception of the Tree Bumblebee, were the species that I've recorded before at Linacre. The Tree Bumblebee is a relatively new arrival in the UK, and is slowly spreading North. More details on the Bumblebee Conservation website here.
Next, the butterflies. In total I saw 6 species in just 1 spot, at the base of the top reservoir dam wall. Species seen were: Green-veined White (c.6), Comma (1), Peacock (minimum of 8), Small Tortoiseshell (2), Orange Tip (2 males) and a Brimstone (my first record for Linacre).
Whilst watching the butterflies, I also managed to spot a Bee Fly - a brand new species for me! Looking on the web, I'm pretty sure it was a Dark-edged Bee Fly (Bombylius major). Details here.
