Hi All,

Hi Chas.
It is Sylvicola (punctum?), Anisopodidae.

I'm sorry.
1. punctata, not punctum
2. It is not S. punctata. So, Sylvicola sp.

Thanks Nikita,

I did look in the gallery but some how did not pick out Sylvicola but I can see the likeness now.

Hi,

Looks more like Sylvicola cinctus.

Hi Jan

Thanks for that, I was wondering about Sylvicola fenestralis as I have just been reading that this and S. punctata are the two common species in England, although S.cinctus has also been recorded.

Is there a visable distinguishing feature between these two or does it require a specimen and a microscope ?

Hi Chas,

With suggesting the name Sylvicola cinctus I may have been jumping to conclusions. Have a look at the following:

This will give you some answers.

Gut feeling says fenestratus... but I have not checked with the key. Sorry, no time as I am almost leaving.

Hi Jan,

Thank you for the key, it is a little technical for me as there are terms that I do not understand so it will have to wait until tonight when I get home and can spend some time checking the terms as well as the pictures against the key.


Many thanks for every ones assistance
