Many thanks for the tip-off, Nigel. This book is going to make a big difference for a lot of hoverfly enthusiasts.
Happy hunting,
John

Four species on the wing in Bedfordshire today - the overwintering Episyrphus balteatus and Eristalis tenax, and two spring Cheilosia, albipila and grossa - the last two species on the garden shrub Vi ...

The link worked well for me at 1842 GMT today.

While I'm posting, I might as well mention that two adult Episyrphus balteatus were recorded in Sandy, Bedfordshire yesterday: sunshine on a south-fac ...

Thanks Rob. That's an amazing tunnel-total in two years! I've sent you a message via the Memberlist, so please look out for it.
All the best,
John

Thanks, and the long antennae make it very likely that they were wasps of some kind: hoverflies have short antennae. If they were wasps, they might have had a "paper" nest in the chimney. ...

Perhaps it was an immigrant English luniger exercising its influence in eastern Scotland. (This was, after all, a West Lothian question.)
Sorry!

I suppose it all depends on where we live, Nigel. Apart from those F ruficornis, some of your recent finds would be pretty stunning for us easterners: Chalcosyrphus eunotus springs to mind, for a sta ...

Thanks and it's good to hear that they are not cluster flies, which can be persistent, and a bit of a nuisance year on year! I've personally never heard of hoverflies behaving like this. A few specie ...

Hallo Pierre.

For your system I think a bright table-lamp or reading-lamp would be good. It should have a flexible neck so that you can get the angle of the light-beam just right. You can choose ...

Are you sure that the ones coming from behind the fire are hoverflies? This behaviour sounds more like that of cluster flies (Pollenia rudis). If you can post a photo, that would help. If not, take ...

It was very interesting to read about Rob's polytunnel. I have access to one here in mid-Bedfordshire which is also an effective hoverfly trap. It's perhaps 7m long by 3m wide by 2.5m high and lies ...

Yes, it must be pertinax because of the pale front and middle feet. I think it looks rather pale-faced because it is of the spring generation which has longer pale hairs than later generations (presu ...

I think it is Meliscaeva auricollis of the spring generation (so-called form maculicornis - see text on page 219 of Stubbs & Falk, 2002). Crucially, the orange spots are set well back from the fo ...

Thanks for this one, Graham.
The liquid in the pot indeed sounds a likely spot for Eristalis eggs to be laid. The larvae are mobile. Normally, they might be expected to climb out of an open pot and d ...
