Lesser known backyard bugs:

The assembled 4-6 mm larvae are Two-spined stinkbugs (Heteroptera; Pentatomidae; Picromerus bidens (L.); Zweispitzwanze; Punaise épineuse). They are exposed to the sun on a Aegopodium leaf. As predators they hunt for insect larvae, caterpillars or beetle grubs and suck on their juices together.

ID: larvae are often looking very different compared to adults. Here you see a last larva of the same species. The depicted larvae for instance show no traces of the mighty prothoracal spines that characterize the adults, presented earlier. The only possibility for ID seemed to me the book E. Wachmann et l. 2007. Wanzen, Vol. 4 that also shows photographs of larval stages. Two spined-stinkbugs occur widely in Europe and throughout Asia to Japan
