The Batman hoverfly, Myathropa florea on hagwort
Nettle tap moth
A male Bombus lucorum swinging from the flowers.
This is a dronefly, Eristalis pertinax.
There were at least three male longhorn, Nemophora degeerella, moths about. They danced as they flew high up. It looks like quite a challenge to fly with such oversized antennae, which presumably attracts the female's attention. This one rested on nettles for a while.
A female Marmalade fly, Episyrphus balteatus, with extended ovipositor.
And to finish, a Speckled Wood. I rarely see these butterflies nectaring. They have a short tongue and like to lap honeydew on tree tops, but the exposed, flat flowers of the hogweed seem to appeal to them.
