Glaslyn: moorland moths

Took a trip up to MWT's Glaslyn reserve the other night. Arrived about half an hour before sunset to find large numbers of moths flying low around the heather. Much to my surprise, almost every moth I netted turned out to be a different species to the last and in just a few minutes I'd built a pretty good list. Peter joined me just as I was setting up the traps and kept me company for the first half of the night.

Trapping site

The night was very calm but due to clear skies, fairly cool. Recorded 37 species in total which is pretty good for a moorland site. There were plenty of the expected species such as True Lover's Knot, Grey Mountain Carpet, Narrow-winged Pug, Dark Brocade, Ancylis myrtillana, Neofaculta ericetella, Aphelia viburnana and Bryotropha politella.

However some of the most interesting observations of the night were species which one would not usually associated with the habitat. This included many species that utilise tree species. This included Larch Pug, Bordered White, Peppered Moth, Pebble Prominent and Pseudargyrotoza conwagana (two of these were recorded). Presumably these are wanderers; just goes to show how far moths move about.

True Lover's Knot and Grey Mountain Carpet

Will return on a warm, muggy night (if such a thing exists on mooland!) next month.

  1. Yes, it was an excellent evening's trapping, especially when you take into account that it was a moorland site as these places are very unpredictable and quite often the weather doesn't 'play ball' at all, but on this occasion we were very lucky.

    It was good to see such large numbers of the moorland species; like the True Lover's Knot and the Grey Mountain Carpet - it was indeed, 'a feast of moths' on the moor.

    Peter.
