[1823] Netted Pug (Eupithecia venosata)

Field Trip - Ashwell Quarry - 18/06/16


On Saturday night the Herts Moth Group made a trip to the far North of the County to Ashwell Quarry.

Having been granted permission from the local land-owner, HMWT and a local neighbour who kindly got us access to the site via a locked gate, we went about setting up 8 lights spread around the Chalk grassland, Quarry and scrub.

Ashwell Quarry is an important site for wildlife and is to be found just outside of the village of Ashwell with it's rich wildflower meadows and chalk grassland. Unfortunately the site in certain parts was swathed in long grass, great for Crambus species but not ideal for the low-growing chalk plants for which the specialist moth caterpillars feed upon.


The weather through the course of the day had been grey, overcast but with little wind and as there was no sun the temperature had struggled to reach 16 degrees.

Upon a arrival at 8pm we were greeted with clearing skies and a bright near-full moon or the 'enemy' as Colin put it.

Thankfully by 10pm as it was just getting dark, cloud began to roll towards us from the North-east and granted us the cloud cover that we so desperately needed if we were to actually catch some moths on the night.

With 8 traps set-up it may have seemed a bit over-kill but I find that the more effort you put in, the more you get out and this was the case tonight where the suitcase Actinic trap attracted both Marbled Coronet and Phtheochroa sodaliana, completely new moths for me and well worth the brave effort of running cables along the chalk cliff face.


The third most interesting moth was a single specimen of the unusual looking Luquetia lobella, a moth that seems to be quite scarce in he County, another new moth for me.


Netted Pug was also a hit with everyone, two stunning examples trapped on the night.


We also got two wetland wanderer's possibly blown in on the breeze which picked up at around midnight, they were Southern Wainscot and Dotted Fan-foot.


All in all a pleasing 108 species were recorded with a few outstanding micro moths to check.
