Another major difference is that bees are 4-winged whereas hoverflies, being diptera, are two-winged. Oddly enough, when I began studying hoverflies, I found that this was not obvious in the field.

Yep. Megachile species, almost certainly M. centuncularis.

Certainly Pipizella virens is on the wing at the moment. I took a specimen in south-west Northants on the 23rd May and although yours is rather early it is perfectly feasible given the very warm sprin ...

Thanks Nigel. I can now stop scratching my head.

For the last few days I have been unable to call up any of the distribution maps despite using the normal procedure. Is it me, my computer - or is there a fault in the system?

The last copy I received of this publication was No 68 in Autumn 2009. Has the publication of Number 69 been delayed or has my postman let me down?

Conopid's observations are very much in line with my own. There have also been Humming-bird Hawkmoths on the wing here in west Northants, all presumably making use of the advantageous conditions.

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 tach ...

Hi Peter,

Surely it is Sphegina clunipes. The position of the r-m cross-vein is the crucial point, being clearly beyond the end of the sub-costal cell. Beautifully clear picture!

Cheers, Tony

At last - hoverflies (Eristalis tenax) visiting the Crocus species in the garden. I attempted to take one but missed. Instead I found that I had taken a specimen of Lonchoptera lutea. Ok, it isn't a h ...

Not a sausage yet here in west Northants. This time last year I was watching early insect visitors to my snowdrops and there were bumble bees on the wing but - sensibly - they're still tucked up somew ...

I can't add to the plethora of suggestions already made, but one thing puzzled me: I have never seen ANY insects on Winter-flowering Jasmine (or, come to that, its relative, Forsythia). Am I unlucky o ...

Hi Mark,

Thanks for your response. Oddly enough I "did" the old Chpping Warden airfield last year and it was quite interesting - and the Pocket Park at Aston-le-Walls is superb. In short, ...

Episyrphus balteatus (DeGeer). The double bar on the tergites makes it very distinctive but recently I seem to have seen quite a few atypical specimens, often very dark.

Interesting topic. Certain male spiders, particularly in the Theridiidae Family, will, after mating, seal the female's genitalia with a "plug" of a waxy substance, presumably to prevent mat ...
