New hover flies for ID Please!

[Janenat]

Hello

I think the first one is Episyrphus Balteatus, the next 2 photos of same hover fly, I think is also an Episyrphus but the markings are darker/faded, does that denote an older hover fly or just different?!

Many thanks

Dark forms do occasionally occur. Usually early or late in the season, although I did see a mid summer specimen this year.

The colouration on that fly is a bit different to those that I have previously seen but offhand I can't think of any credible alternatives.

So unless anybody else has any suggestions I would say it is a dark form of E. balteatus.

Morning Jane,

Yes, Episyrphus balteatus certainly. The colour varies on the abdomen, a more key-point is the three subtle white lines on the thorax.

Take care,

Jason

Thanks for that, it was the 3 lines on it's thorax that I'd noticed that made me think they were the same
