Belle

I agree this looks like July Belle, but I'm not confident of distinguishing it from Lead Belle (I don't get either species in my part of the world) - is Lead Belle also a possibility or do you think the markings on this one are clear enough to distinguish it?

Bit of both really, this

Bit of both really, this species is much commoner in the county than Lead Belle (which isn't very rare but still uncommon), I think the markings go a fair way to ID'ing these, based mainly on the position of the discal spot and other markings, my CR seemed to agree it was July Belle. Also I think Lead is more of a moorland species, whereas July is more ubiquitous. (I live nowhere near moorland)

Best wishes,

Douglas

Hi, Once again I have to

Hi,
Once again I have to admit that my agreement was based solely on the illustrations in Waring and Townsend, (The fact that Douglas IDed it as July Belle is a not insignificant factor also).

Of the 4 illustrations offered at the top of plate 211, the one to the right is July Belle and the 3 to its left are Lead Belle.
The above moth just looked virtually identical to the offered illustration of July Belle in markings and colouration.

The straightness and lack of undulation to the dark extremities of that central band (the cross lines) seemed to resemble the above insect more accurately than the corresponding markings on Lead Belle.
Looking at it now, the rear extremity of that band seems to be a little closer to the trailing edge of the wing also.

Thanks

Cathal.

Yes, also note the position

Yes, also note the position of the discal spot. If you look at photos:

July, see spot towards top of band

Lead, spot different shape, spot more central
http://ukmoths.org.uk/show.php?bf=1733

Of course, variation and so forth means this isn't always accurate, but due to habitat I'm happy with this being July.

By the way, Cathal, I'm sure you know this already but W&T have illustration which are often exaggerated to show features and cannot always be fully reliable. It's always useful to bear in-mind when ID'ing using W&T. Having said that Lewington (in my opinion) is the best illustrator for natural history and does a very good job of representing the species, I'm very much looking forward to his new complete micro guide in the coming months.

Best wishes,

Yes Douglas those subtle

Yes Douglas those subtle exaggerations can be very helpful and decisive but at times, when not fully aware you are viewing an exaggeration, they can leave you a bit stumped and frustrated!

Looking forward to the micro guide too, Ive heard talk of it for a few years now but I didnt realise it was actually as close as you say. It will be very good to have because when I see nice looking micros, I sometimes wonder if the ensuing 'bother' of having equiped myself with images of them is worth it. Macros are challenge enough for me at the best of times!

Cheers for those links.

Cathal.
