St. Agnes offers excellent opportunities for trapping rare & scarce migrant moths in the right conditions. We had several good “Moth Nights” during the week with warm southerly wind, despite being  a little late in the season though.
We ran a Mercury Vapour Light & Skinner Trap each night from 15th – 20th October and we were located at Troy Town Farm on St. Agnes. The best evenings were 17 & 18th October with warm southerly winds, cloud & slight drizzle.A Dark Mottled Willow was trapped by Mike Hicks on the 15th October – a first record for the Isles of Scilly. A second was trapped on 17th October by Mick Scott. Also during our week a Tunbridge Wells Gem was trapped on St.Agnes.
Highlights of the week were –
9 of Plutella xylostella (Diamond-back Moth)
3 of Hellula undalis (Old World Webworm- Rare migrant)
Nomophila noctuella (Rush Veneer – good numbers)
1 of Palpita vitrealis (Status scarce migrant)  
2 of Scarce-bordered Straw (Scarce migrant)
1 of Cosmopolitan (Status scarce migrant)
 6 of The Gem (Status scarce migrant)
