Raised bog moth trapping

Postby IainH » Tue May 24, 2016 5:30 pm

I’ll be mothing at a raised bog outside of Stevenston this year, so - because it’s not in Stevenston - I thought I should start a new thread.

My first trapping session with a small 15W heath trap produced 5 moths of 5 species:

Nut-tree Tussock
Poplar Hawk-moth
Small Square-spot
Hebrew Character
Flame Shoulder

(Despite the abundance of both Birch trees and moth recording at Ardeer Quarry LNR, I’ve never caught a Nut-tree Tussock there for some reason.)

Also, I swept the common micro moth Micropterix aureatella from some nearby Bilberry, lots of Common Heaths were flying over the bog and I swept a Heath Rustic caterpillar from the heather.

Cloudier and warmer than my last trapping session, but two traps produced less than last time.

I visited two raised bogs - Auchentiber Moss and Dykeneuk Moss - in North Ayrshire today. Lots of Common Heaths were on the wing at both sites. On Dykeneuk Moss, other, larger moths were flying around. At least a couple were Ruby Tigers. Lots of Epinotia tetraquetrana, a Birch-feeding micro moth, were flying around too. Despite being a relatively common species, there don’t appear to be any previous Ayrshire records.

A much better catch at the bog than last time, owing to the favourable weather conditions.

This micro moth has been troubling me for a while. I think it's Orthotaeria undulana rather than Piniphila bifasciana, as I first thought.

Hi Iain,

after a slow start it must be encouraging to see numbers and species pick up. Worth all that tramping back and forth!

Alistair.

Raised bog moth trapping 7th June 2016

The highlight at the bog was a Saxon (Nationally Notable, Nb) on one of the traps. Other than that, there were a few more common species to add to the site list and 3 Campions was the largest number I’ve ever caught - I usually only get one or two a year back at Ardeer Quarry.

A Latticed Heath was flying about near the traps, as was another Bordered White. Cork Moth and Anania fuscalis were new micros for the site.

Raised bog moth trapping 22nd July 2016

A mild, cloudy and calm night. A single 25W heath trap produced a diverse catch. It was nice to escape Ardeer Quarry’s Large Yellow Underwings for a night! It's also nice to see things that don't turn-up often or at all at Ardeer Quarry, such as Northern Spinach, True Lover's Knot and Twin-spot Carpet.

Raised bog moth trapping 18th August 2016

Postby IainH » Sat Aug 20, 2016 10:10 am

The highlights in a 25W heath trap were a Haworth’s Minor and lots of Water Veneers, a local wetland micro. Haworth’s Minor most likely feeds on the abundant cotton grass at the site. Water Veneer was more abundant in the trap than I’d ever seen - there were 11 in the trap. Unusually, some were still alive (the species is apparently infamous for appearing dead in traps, and my experience of them testifies to this).
