I was passing the site this afternoon so I called in to have a look for larvae on the foodplant Common Gromwell, which is abundant along the ride sides this year following ground disturbance due to timber extraction works.
The first plant I checked had larvae on it, and pretty much every plant I found had obvious feeding damage. Many of the plants were in a terrible state as the larvae had stripped all the green material from the leaves.

If anyone knows any other sites in South Wales with Common Gromwell it would be well worth checking them for larvae.
