Nematus species
Many Sawfly larvae are greenish speckled with black dots and lines and bold. The larvae on this page are very similar to other Sawfly larvae indeed, but when you look closely you'll notice some differences: the pattern of the black dots is different and it has a yellow head. We have no idea what species they represent, but larvae of Arge, Tenthredo and Nematus species all are more or less like this.... One of the Rose Sawflies, including Arge pagana, is a good candidate, though. Should you be able to tell us which species it is, please let us know!
