Hi Pterodroma,
they are both Eristalis spp. The left hand one is probably arbustorum and the other looks like tenax. Was this one much bigger than the first?
Cheers,

Steve.

Hiya Steve

Yes, the second was much larger (it was a large species of hoverfly).

By the way, I'm intending getting the book you recommended (but it's currently about the fifth in line!!)

Best wishes

Hi Brian,
it looks like a worn specimen of Cheilosia illustrata to me. There is usually more of a covering of coloured hairs on the tergites but looking at the state of it's wings it's been through the mill!
Cheers,

Steve.

Thanks Steve, I like that suggestion. It was starting to annoy me. I was even considering a wasted lucorum.

This is Melanostoma scalare - very clear from the dust marks on the frons. The other dusting is a fungal attack that often hits Melanostoma and Platycheirus.

Any data on where photographed, when and grid ref?

Roger Morris - see www.hoverfly.org.uk for contact details

The secon is a Chrysotoxum species, perhaps arcuatum?

I'd still be grateful for any comments on the previous insects.

Ta!
Brian

The Chrysotoxum is festivum - arcuatum is a northern species close to verallii

Do you have details of records? the recording scheme is interested in records that we can verify - see www.hoverfly.org.uk for contact details

No, this is Leucozona lucorum - the scutellum is yellowish and the shape is wrong for C. illustrata

Hello Hugh

the second one is a Parhelophilus - but cannot say which. I've looked at your website and may be able to help with quite a few of the images - contact me at roger dot morris at dsl dot pipex dot com - I think I'll need to look at originals but can probably do a reasonable proportion.

Hope you've got details of where and when photographed as the data would be useful for the recording scheme

Regards

Hi Roger, and thanks for putting me right! [Sigh of relief] at last, we have a real expert on the forum!
Although I am gaining knowledge all the time it is obvious [as on this occasion] that I have much to learn. For example I have not knowingly come across a 'dark' L. lucorum before but now it's been pointed out the other features you mention become more obvious.
Best Wishes,
Steve.

Hi Roger. Great to have a hoverfly expert among us and thanks for the IDs and corrections.

I photographed V. inanis at Peterborough at the weekend. My first this year.

Hello Brian,
I found a female V. inanis at a new site in Wilts last week. At the Wilts Wildlife Trust reserve of Ham Hill near the boundary with Hampshire. Unfortunately she wouldn't keep still long enough for me to get a pic. Also one Xanthogramma pedissequum there. It's been a good season for them in Wilts this year.
Cheers,
Steve.

They are in order

Records of Hovers

Hi folks

There are obviously a fair few recorders out there who perhaps get records of a few hovers that might be of use to the Hoverfly Recording Scheme www.hoverfly.org.uk

Do please hold on to details of even common but identifiable stuff with - date, location and grid ref. I'm happy to have a crack at photos and will accept records of species I'm reasonably happy can be ID'd w/o too much experience - may ask for vouchers for some. But, even the assiduous photographer can make a contribution - very neary all of our analysis of Volucella zonaria come from odd snippets of data by interested observers going back 60 years!

Species worth keeping note of that can be ID'd w/o too much difficulty include all Volucella, Epistrophe eligans, Rhingia campestris, - and a fair few more. Some can be useful in understanding climate change as well as distribution changes. Can a few of the gaps on the Volucella maps be filled in?

Hope to hear from you - my e-mail address is roger dot morris at dsl dot pipex dot com.

Regards

Roger

That reminds me I had my first R. campestris for the garden the other day. I'll try to remember to record more sightings via the website.

Thanks for the lucorum id. I've only come across this species in spring before.

Yes, it would be quite helpful for me to know how you tell if a fly is a hoverfly or not. I photoed something in the garden the other day (4/9) and then thought that it looked more bee-like.

The eyes have it! Take a look at some pics of each and see what I mean. The garden safari site is a good place to look:

OK, it looks as if the Syrphidae eyes are larger in relation to the head and come closer to meeting each other. The bees often seem to have three prominent occelli.
BTW I came across this URL
http://homepage.ntlworld.com/keith.b.../html/year.htm
which might be quite useful for anyone in central southern England who wants to know what species to look for in any given month. the hoverfly site gives you the option of printing off a checklist for your post-code... though it's not in a very convenient format. Mine (RH7) ran to six separate web pages.
Would this one (below) be a hoverfly... probably not IDable, it was a fairly medium sized fly.
Most of the hovers I could see in my garden today were quite small and way beyond my photography skills.

This one is definitely a hoverfly.
I thought it might be Syrphus ribesii but am far from sure.

Posts #70 and #72 look like bees to me but it's hard to see for sure. The Surphus sp. can't be done from the photo (unless Roger says it can).
