I swept the heather and found a small caterpillar that is possibly Neglected Rustic. I have seen these on the Calderdalemoths blog recently.

The Ectoedemia weaveri mines on Cowberry now have visible larvae when the leaves are held up to the sunlight and viewed with a 10x hand lens.

There seem to be two different types of tortrix larvae creating spinnings on the Cowberry. These are predominantly a dark type but there are small numbers of a brown-headed paler kind. I will have to rear these to see what emerges.

A Rhopobota ustomaculana resulted from the pale larva on 20th May 2010
