Have a look at Volucella inflata, a hoverfly with dark wing patches, an orange scutellum (projection at rear of thorax) and the orange sides to the thorax. Looks good for that.

Where do you live...I am sure the record would be welcomed if you have a grid reference, say.

Ian

Is the scutellum part of the thorax or separate?

Thanks

Hello Rob

Can you use OS grids please - I have trouble with Lat-Long.

Regards

Liz

The scutellum is the third division of the thoracic dorsum, and in hoverflies is always obvious, as a projection at the rear of the thorax proper.

It comes form the diminutive form of the Latin word scutum...a shield , and so means "a little shield".

Hi Rob,

Are you sure you haven't got two species here? Although the first photograph shows what looks vaguely like a hoverfly, the curved leading edge of the wings suggest that it is in fact a tachinid, Phasia hemiptera. There are plenty of confirmatory pics on the internet. This striking-looking fly is a parasite, its larvae developing within the body of various shield bug species.

Thanks Ian

Do you have a diagram with all the parts of the hoverfly named including the wing?

Would be very useful for explantions and I have alot of hoverflies to add to the recording scheme

Hi Elis

Are you using Stubbs and Falk (British Hoverflies) for your hovers? If not, get it! It has the pictures to which you refer.

What about Dipterists Forum? If you join that, you have access to their resources, which include guides to diptera ID and families...etc. A superb resource, with very detailed images of fly anatomy.

Hope that helps.

Ian

Hello

The best bet is to join the forum and the buy Stubbs & Falk at the reduced rate available to members.

Regards

Roger
