Old observation from 17 Aug. 2019.
@ 2.40pm
It examined insect holes in an old, rotten birch trunk (my natural insect hotel). The holes were used by Stigmus https://insektenf...99082& and Crossocerus https://insektenf...99138& wasps.
Body length +/- 6mm without antennas and ovipositor. Insect holes 1.5 to 2.0 mm in diameter.
Notice the strange way it walks - see the video https://www.youtu...-7ah1STxhI.

Many Thanks
Ray

@ 2.56pm.
When viewed from the side, the metasomal / abdomenal segments widen towards the posterior end, giving it a more blunt end.
There seems to be something stuck on the side, the little grey triangle it's trying to remove with its hind legs - see video https://www.youtu...DDZQBU4QUw.

Hi Ray, it could be a wasp of the Braconidae - Alysiinae.
