Hoverfly on a Gorse bush.
No interactions present.
That's another one I will now know next time I see it.
One of the common hoverflies which live up to their name by hovering at around head height around hedges and woodland edges. Very common in late spring. I've not seen one yet, this year...yours is quite early.

The commonest hoverfly here is Episyrphus balteatus, which I am already seeing and which last year was also about the last one to disappear.
Episyrphus balteatus is very unlikely to be your commonest hoverfy at the moment, though. A few overwinter, so a few can be seen at this time of year. But, there is a usually a lean spell for the species through the spring, before the summer, when it really takes off, some years. At the moment, Eristalis pertinax is far and away the commonest species around me.
Yes, that's a year-round estimate of commonness really. There are only a few E. balteatus just now. Some other species flush during the year, too, briefly becoming the commonest, e.g. Scaeva pyrastri early last August.
