Hi, at the underside of a leaf of Betula pendula (birch) I found a structure, which I cannot determine. Any idea? Germany, Hessen, Grunberg, 2015-06-03 Thomas Brand attached the following image:  [69.29Kb] Edited by Thomas Brand on 08-06-2015 10:44 |

Hi, In the meantime it is obvious, that thes were eggs of a sawfly. There is a big number of possible species, it might be Croesus septentrionalis. Thanks for any comment Thomas Thomas Brand attached the following image:  [159.14Kb] |
