I am extremely sorry for the tiny pics! This observation is part of my attempt to safe some of my older observations. Unfortunately, the original pictures have been lost and these are retrieved from a nature-internetforum, where I posted them back then. Unfortunately, the forum also had a data crash at some point, so only the tumpnails are left. I try to upload only those observations of which I think, they might be verifiable even with those small pics only. Again sorry!
