Some kind of bug, I'm not sure what it is. It jumped when I touched it instead of flying away.
a four-spotted chaser (skimmer in the US), Libellula quadrimaculata
a male broad-bodied chaser (Libellula depressa), the females have a golden abdomen. They are rare and I hadn't see one in ages. Nice to know that they are still around. Both species are fairly big dragonflies, with a bodylength of almost 2 inches.
