I am new to this game but I think that I have photographed the above this morning near Inverness in the Highlands of Scotland. According to the distribution maps and write-ups, I must be wrong! It was in a large clearing in a wood and the weather was warm and bright with the odd shower.

Can someone help with a positive ID (I have more photos if they would help) and if it is what I think it is what should I do now?!

Thanks

Your photos is of Crysotoxum arcuatum, long antennal segment 3 - longer that 1+2, and all yellow scutellum (rear lip of the thorax). C cautaum would have 3 = 1+3 and a large black center to the scutellum. Check out the photos in the species accounts which can sometimes help. HBRG would be very happy to receive the record. Keep posting your excellent photos with supporting data.

Brian.

Hi

From the location, it should be Chrysotoxum arcuatum.

The third section of the antennae looks very long, longer than the first two, smaller sections, put together, which does make it arcuatum.

Very nice! If you look at the maps section of this site, you'll see that it a northern species, found around Inverness.

Many thanks for that. I do have hundreds of hover photos, only a few of which I have identified. They are mainly taken in or around Inverness but there are a few from London and other places.

This site is like heaven to me!

Hello

We will do what we can to ID photos for you. What would be useful would be to provide biographical details for the photos - where taken, when, grid ref (or postcode) and recorder name. These can then be incorporated into the database that builds the maps and other analyses such as the climate change work Stuart has been doing.

Regards
