Autumn can be a time of great excitement for Devon’s moth recorders as moth migrate northwards from the continent and arrive on our shores. In some years, little arrives but in others (most recently 2013 and 2011) an amazing variety of common, scarce and downright rare immigrant moths come in, to the delight of wildlife enthusiasts.
So far this year, most of the migrant moth excitement has been among moth recorders on the east coast of Britain. However, the South West hasn’t missed out entirely. Perhaps the pick of the crop so far have been two records of the large and dramatic Clifden Nonpareil (Catocala fraxini) – a moth that would feature on most moth recorders’ bucket lists. The first was caught by visiting moth expert Dave Grundy at Prawle Point on 27 August, while the second came to Mike Lockyear’s moth trap in Crediton on 17 September. Both are shown below. The species has also been reported from other locations around the English coast from Dorset to Northumberland in the past few weeks.
A range of other immigrants have been seen in Devon in recent weeks including the massive Convolvulous Hawk-moth, Delicate, Vestal, Scarce Bordered Straw and Ostrinia nubilalis.
With mild conditions forecast for the week ahead, it would be well worth looking out for rare visitors to our county.
