Look at these two sawfly larvae. I guess they are very hard to be identified down to species or even genus level. But maybe is there someone who has an interest or specialization in this group of insects. The larvae have been captured in cereal crops on a cornbind - Convolvulus arvensis (first picture) and thistle - Cirsium arvense and/or setosum (second picture). The leaf damages can be seen have been made by these larvae but there is no strong confidence in their food specialization. I mean they could feed upon other plant species (maybe even cereals). To make your identification somewhat easier I attach two pictures of adult sawflies occurred in the same cereal crops most frequently. Maybe there is some relation between these larvae and flies.
Good luck in id. and thaks advance!
