Incident sunlight reflecting a concentrated bright shimmer pulled my attention to an object floating in water. A small chalcid wasp, ±4 mm in length, floated submerged in water. It turned out to be a female Perilampus aeneus [1,2], a parasite on Curculionidae (Coleoptera), Tenthredinidae (Hymenoptera), Tortricidae (Lepidoptera) [2] and Tachinidae (Diptera), Blepharipa pratensis and Parasetigena silvestris [3].

During examination with a magnifying glass it became clear she wasn’t dead yet but not much life was left in her. Shortly after she passed away and is now part of garden collection.
