Bactra robustana

I recently dissected a Bactra which was trapped at Merthyr Mawr on 22/8/17. It looked a decent shout for B. robustana, a saltmarsh species, but I struggled to make sense of the genitalia preparation and so posted some photos on the Moth Dissection Facebook group. Raymond Watson quickly replied to say it was indeed robustana and gave a detailed summary of the clinching features.

 

This would appear to be the most easterly VC41 record though my MapMate probably isn't quite up to date.
