Comment on ‘A world without males: How the elm zigzag sawfly is benefiting from their absence’, Dr Max Blake, Forest Research by wtdigital

Hi Claire,
If you could please report this to Tree Alert this will go straight to the tree health teams at Forest Research. This could be a cause for concern if this was an Elm Zigzag Sawfly and was released in an area it is currently not found in.
Many thanks
