I wasn't sure if the

I wasn't sure if the cornicles were long enough for fragariae. The two species are very similar and, I think, differ only in the length of their corncicles.

I will defer, but...

..based on my image, if I was asked to choose between:

(Sitobion fragariae (Walker, 1848))

Sitobion fragariae, or

(Sitobion avenae (Fabricius, 1775))

Sitobion avenae,

I would go for S. fragariae, for although there is some slight foreshortening in my image, I would say its cornicles are longer than those seen in the linked images of S. avenae.

Looking forward to what you have to say..

Have a great 2013,
