Moving about on bramble
No interactions present.
The antennae have lots of segments, which rules out most sawflies and suggests an ichneumon or related type of parasitic wasp. The ovipositor at the tip of the abdomen is longer than any sawfly would have.
Most sawflies have nine or fewer antennal segments; the few exceptions can have up to 23 segments but in that case they are distinctly segmented or feathered, as far as I know.
Entomologist and biological recorder
Many thanks. This seems to be a tricky one. A relative of Amblyteles armatorius perhaps?
Many thanks for the comprehensive notes. (I have since posted an image of what I believe may be Tenthredo atra - my first inaccurate suggestion for this species.)
