Hovers

Post by diggleken » Thu Jun 04, 2015 1:02 pm

Some nice ones starting to appear - look out on Ramsons for this, Portevinia maculata and a black one, Cheilosia albitarsis - Cheilosia are difficult without seeing appropriate features - in this case, all black legs with just a bit of paleness on the front legs after the foot segment......its a bit more than that, but that'll do for now...............
Cheers
Ken

Great photos Ken!
This is what I found today, on a blade of Yorkshire Fog:

Hoverfly larva?
Someone suggested it might be the red form of Syrphus ribisii.

Hi Jimmy, you need Graham Rotherays book on Hoverfly larvae to help, which I haven't - but I know its not from Eristalini, rat-tailed maggots in damp/watery conditions, but as for Syrphus spp, I don't know.
I don't know what they mean by the red form of Syrphus ribesii - there isn't one............. :o
I'll keep looking on't web, but needs expert knowledge or the book I think - or post on dipterists forum or put on FB Hoverfly pages - if you want me to do that, let me know....
Cheers
Ken

I'm not saying I'm believing them when they said it was the red form of S. ribisii (I thought it sounded strange!), but here's the link to the observation on iSpot anyway: http://www.ispotnature.org/node/684991
I don't have Facebook so it will be great if you could post this on there for me!
Do you know any good dipterists' forums?
Thanks again by the way! :)

Hi Jimmy,
this may help for diptera in general:
http://www.diptera.info/forum/viewthrea ... ost_251257
I'll post on FB Hovers after tea and the cup final.............tomorrow then.........
I cant understand what on earth they mean by red Syrphus ribesii - perhaps I'm ignorant of that - note the poster cant spell species name correctly either though......
Cheers
Ken

I saw the name spelling too, but stupidly chose to copy and paste the comment out of laziness without paying much attention to what it said. I'll have a look at the website you linked soon.

Thanks for posting on Facebook and I wasn't expecting a species ID at all. Although I can't see the page, I'm not on Facebook, remember... ;)
Maybe screenshot it (Alt + Printscreen, I think. Maybe Contrl + Printscreen, I can't remember) and post it here??

Hi Jimmy - deep apologies - it seems there is a red variation for Syrphus ribesii larvae - news to me - - page 135 or so I think in the attached. Good stuff.

Cheers - and apologies to your original responder too ........ 8-) Need to get their spelling right though...............

That is interesting, Ken, I wasn't thinking that the red form would only be in the larva and not the adult.
Again, if the link does go to Facebook then I can't see it, but the link doesn't seem to be complete anyway.
