Northern Eggar, Mompha raschkiella and Beetles

The first of my Barden Moor, Northern Eggar caterpillars has produced this male imago. I photographed it this morning and it presumably took advantage of the afternoon sunshine to zoom off back towards the moorland.

My remaining caterpillar has yet to pupate.

The second photograph shows a mine in the leaf of Rosebay Willowherb which I think was made by the larva of Mompha raschkiella.

The final picture shows five beetle larvae devouring a leaf of Rosebay Willowherb (Epilobium angustifolium).

It will be a challenge to work out which species of beetle this is!
