Sorry all but a bit pressed for time so have had to upload all these on one thread. All taken in Bristol, at different times of the year. Any help appreciated.

top middle a Hoverfly, Top R is a Cranefly, top L Muscid?

bottom right and left are Sawflies, second from right Stonefly, second from left Blow-fly.

Evening Seb,

#1: Muscina prolapsa??
#2: A hoverfly I think - do you have a dorsal?
#3: Maybe a Limoniidae member? (Generally called Folded-winged Craneflies - they fold them over their back as opposed to at 90' angles as in Tipulidaes, for example)
#4: Arge/Athalia sp. Maybe Athalia rosae?
#5: For the sake of accuracy I would need a facial or direct side-on, but an initial look makes me think the common Calliphora vicini which has an orange 'Anterior spiracle', AKA a breathing hole. Other pointers include orange cheeks.
#6: Caddisfly??
#7: Oooh, the genus escapes me!

Take care,

Jason

Evening Jason!
Wow thanks guys. And thank you Jason for such a detailed answer. No dorsal Im afraid, these pics were one click shots probably why I still have them unidentified! The Caddisfly I must admit I thought was a Stone fly but someone else also told me a Caddis. Its interesting because it looks so dissimilar to other caddis flies I have shot

Top Left Helina Likely H.Impunctata
Top Middle (Do you have a larger image something that shows the wings more clerly?)
(Bottom Second Left) Calliphora sp (Carnt see an orange spiracle Jason?)
(Bottom Second Right) Do you have a side view which shows the wings? Its a Limnephilid

Sorry just seen that you dont have any other photo's! Can you enlarge the hoverfly photo?

Quite right you are, Dan. Neither can I, so not sure why I said that! '

'

I think I said it as a starting point - that I thought that bit may be obscured and that statistically it's likely? I shouldn't have gone that far without waiting for a further image, though. Point quite obviously taken!

I wouldnt worry about it Jason I do that sort of thing all the time its nice to get it to species but sometimes its best to leave it as it is. You carnt see enough detail to be exact (Well I carnt anyway).

Thanks all for your views. Unfortunately Dogghound I am not much help, the largest I have of this image is a shown. If I enlarge it will just end up a blur. Sometimes genus level isnt that bad though, its better than having an unknown!

Just googling some images on pic No.1. Helina does not seem to have the thoracic stripes that my specimen shows, whereas Muscina does. Any thoughts?
