Second species of wasp-like creature on ring-barked Sycamore

Observation - Second species of wasp-like creature on ring-barked Sycamore. Description: Not clear to me whether, with such a short ovipositor/stinger this would be a predatory or parasitic species...(or a sawfly) Further to my previous post: “Insects on a ring-barked Sycamore tree”; to iSpot 10th March, 2014
