NORWICH: Sawflies on Ash - Tomostethus nigritus

Early June 2023

Whilst checking an Ash tree for psyllids I noticed some very bright green caterpillars feeding on some of the leaflets. A closer look revealed they were sawfly larvae, and fortunately they were distinctive enough to identify them as Tomostethus nigritus, a new species for me.
