Butterflies and Moths this weekend!

I seem to have spent a lot of time this weekend seeking out Rosebay Willowherb (Chamerion angustifolium) in an attempt to find leafmines of Mompha raschkiella. It is Dean Stables's fault for publishing a photo on his blog! I'm also looking for Mugwort at the moment and Phyl Abbott (Plant Atlas of Mid-west Yorkshire) suggests that this often grows with Nettle and Rosebay Willowherb in unmanaged grassland.

On a nettle-patch between Jerrison Wood and Spring Wood at Esholt I saw the greatest concentration of Commas that I have ever seen in one place. There were also Red Admirals, Large Whites, Ringlets, Meadow Browns and Gatekeepers.

I will try to remember to return here at the end of August to search for Comma caterpillars which I have only ever found on elm.

I could only find vacated mines on the willowherb apart from one which seems to contain several tiny beetle larvae.

I will have to keep searching the Rosebay Willowherb in the hope of finding a tenanted mine.

Stopping the car by yet another stand of Rosebay Willowherb, near Menston, I noticed this Yellow Shell (Camptogramma bilineata).


  1. Hi Derek, I reckon it's getting a little late for finding tenanted raschkiella (summer) mines. I found one a couple of weeks ago which emerged this afternoon - a splendid adult ichneumon/braconid wasp!

    Lovely blog by the way - full of inspirational posts.

  2. My fault, Derek!!!. Was it only tenanted mines you couldn`t find ?

  3. Hi Dean & Charlie

    I can only find vacated mines that look to be attributable to Mompha. I think that you are right; I may be too late.
