Sammanfattning

en: This 4-5cm long larva was crawling around on the ground near rest area "Lucasgat" on the dutch A1 motorway in an area that has lots of oak and pine-like trees (and maybe some birch too). It rolled up when the camera came too close and clutched a little twig. I ripped the twig out of the ground and photgraphed the head upclose from the bottom (protected side) (see other picture). As I know nothing about these critters I looked and asked around and it seems this would be the larva of a Birch Sawfly (Cimbex femoratus).

Update: According to Doc Taxon it is a Cimbex femoratus larva. Doc Taxon states that for other species with very similar larva (Cimbex lutea and Cimbex fagi) the "warts" would be smaller and more cone-shaped as oposed to the larger and more "Zuckerhut"-shaped warts on the C. femortaus. The German word "Zuckerhut" refers to a suger cone with fairly steep sides and a clearly rounded tip used in the preparation of Feuerzangenbowle. See Wikipedia:English or German.
