Mid-winter migrants

2015 was an astonishing year for migrant moths in the county and concluded in style with the appearance of another species new to Devon. The incredibly mild, and often strong, southerly winds that dominated December’s weather continued to bring a host of migrant moths to our shores.

One very small visitor was of particular significance. Syncopacma polychromella, is a tiny but distinctive Gelechiid micro-moth with a wingspan of only 7mm or so.It occurs in southern Europe, Africa and the Middle East and has only been recorded in Great Britain on a handful of occasions prior to December, and never in Devon.

That all changed on 16 December 2015, when visiting moth recorder Dave Grundy caught a S.polychromella at Prawle Point, the first ever Devon record. Amazingly, the following night, two more examples were caught in the county: one by Mike Braid at Chittlehampton, south of Barnstaple, and thus the first ever record of this species in VC4 (North Devon) and the other by Richard Fox at Abbotskerswell near Newton Abbot. These latter two records were both from garden moth traps.

The three Devon records of S.polychromella formed part of an unprecedented influx of this species into Britain during the week before Christmas. In all, over 60 sightings have been reported so far, mainly from south-coast counties but also from inland locations such as Surrey and north Wiltshire.

Just goes to show that you should never pack your moth trap away for the winter!
