Its the first of either that Ive seen and unfortunately it is a bit faded. Is the abdomen difference an easy check to do as I still have the moth in a tub nectaring on a piece of sugar dipped tissue?
Could it be done by looking at the moth from below?
I think the reason I opted for Treble-bar was due to the closeness of the 2 rear bars, just going by the illustrations in WTL. There is a bigger space between the bars on Lesser TB in the illustration and I took that to be diagnostic but maybe not as you point out.
Edit- Just had a look at the drawings of the abdomens in Waring. This one appears to be a male Treble-bar by the shape of the pointed turned in claspers.
Thanks for pointing this issue out to me David. If I had read the info on the species before I'd posted I'd have been able to do the check previously. Without the check the moth could very well have been either of the 2 species.
On the basis of that description of the claspers I have been able to agree with the identification of this as Treble-bar.
I stuck in a crop of the underside of the moth above showing the claspers.
with any of these you capture. As far as I know there is only one other abdomen shot on iSpot, one I took some time back (http://www.ispot.org.uk/node/78335)
