Found wet and clinging to a leaf by its mandibles.
No interactions present.
Probably barking up the wrong tree, but it couldn't bee a species of Stelis could it?
Stelis have a relatively short and broad abdomen, so this appears to be either Chelostoma campanularum or Heriades truncorum. It's hard to be certain but I suspect the latter, as campanularum has a strongly elongated thorax and lacks hair bands on the abdomen (as reported via Twitter)
