| | | Hoverflies for id confirmation or refutation :)
Hello,
Would any of the hoverfly enthusiasts care to cast their eyes over these pictures for comment?
Four seperate individuals from South Devon, 3 at flowers of Burnet Saxifrage in a layby of the A38 and 1 on lesser hawkbit, smallhanger clay workings.
I think (from bungling around with Stubbs) that they are Episyrphus balteatus, syrphus ribesii and two individuals of Scaeva pyrastri. All common hoverflies.
However I'm a complete novice and may well have hugely fouled it all up! So opinion welcome.       |

Agreed except for the Syrphus, S. ribesii females have all yellow hind femora or black just at the base at the most. That will have to remain Syrphus sp.

Thanks Janet.
I must confess my ident of the syrphus hinged on what I thought was a completely yellow femur - looking at pic 2 now I can see there is a suggestion of darkness which I took to be shadow - I was hoping the part black femur referred to in Stubbs would be a little more cut and dried than that.
As always I need better pictures
Regards,
Matt | | |
