Great numbers of these tonight!
(Small wasp at top right) with two other smaller ichneumons (similar, maybe the same as those in https://www.inaturalist.org/observations/4224663 which is just outside the greenhouse) and Polistes apachus wasp nest in the greenhouse.

The Ichneumonoidea are insects classified in the hymenopteran suborder Apocrita. The superfamily is made up of the ichneumon wasps (sometimes inaccurately called "ichneumon flies"); family Ichneumonidae and the braconids (family Braconidae). Like other parasitic wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, but actually not a monophyletic group.
