The Hoplodrina species are tricky to identify (certainly for me!!) and it might be beneficial for other iSpot users if you could point to the characters which allowed you to determine this was H ambigua rather than H blanda or H alsines.
One of the most distinctive features of Vine's Rustic is of course the hind wing which unfortunately is not visible in this picture.
I am not suggesting your ID is incorrect but as iSpot is intended amongst other things to be a learning resource it would be useful to record your reasoning in reaching this ID.
Fair point! This was an individual about which I had no hesitation (whereas I would have had real concerns about blanda/alsines).
This individual is a small Hoplodrina (FW 13mm) and has a slightly stubby, sawn-off look (presumably a side effect of the "rather angular" shape to the forewings noted in Townsend/Waring). These are characteristics that I associate with Vine's. More importantly it is a plain, greyish moth and has very large, well-marked stigmata.
Interestingly, of the 6 moths currently showing on my view of this page as "Other observations of Vine's Rustic", I believe that at least three of them are probably not H. ambigua - I've added Hoplodrina as an identification for two of them and H. superstes (Powdered Rustic) as a possibility for another. This is a difficult genus.
