A Stoat crossed my Path

I spent another few hours on Barden Moor yesterday and found this female Philedonides lunana resting on a Cowberry leaf. It isn't recorded very often in Vice-county 64, presumably due to its early flight period.

The lunana was the last find of the day and the weather was closing in as I descended from Upper Barden Reservoir. I used the UKMoths.org.uk site to identify it, the illustration in Razowski bearing no similarity to my moth.

A Stoat crossed my path as I walked along the eastern edge of Lower Barden Reservoir where the Cowberry grows in abundance.

I was already pleased with myself having located a couple of examples of Phyllonorycter junoniella and a Northern Eggar caterpillar.

I can now categorically state that the multitude of dark larvae spinning the Cowberry here are Olethreutes mygindiana; one of these emerged, yesterday, from a specimen collected earlier.

A tortrix larva on Cowberry.

When I brought my Cowberry plant to the Bramham meeting a couple of people pointed out that the leaves on one of the plant tips were spun together into a hibernaculum.
Today, I decided to have a look inside and, sure enough, a rather active, small, dark tortrix larva was revealed as the industrious occupant.
A text search of the UKMoths website leads me to believe that it is likely to either be Rhopobota ustomaculana or Olethreutes mygindiana. According to Sutton and Beaumont; the first species is said to be "Recorded among cowberry on the Pennine moors in vice counties 63 to 65 where it is locally fairly common." The latter is also described as "Locally common on the higher moors."
I will rear the larva through to the adult and, having just read the description in Jozef Razowski's Tortricidae of Europe I am expecting it to be Olethreutes mygindiana.
