The Devon Moth Group AGM and winter indoor meeting that had to be cancelled at short notice last week due to snow has been rearranged. It will now take place on Thursday 21st February. See Events page for details.
Moth Night, the annual celebration of moths and moth recording, has come around again and takes place on the three days and nights of 14 – 16 June 2018.
The UK-wide event, organised by Atropos, Butterfly Conservation and the Centre for Ecology & Hydrology, will focus on pyralid moths (the families Pyralidae and Crambidae), the first time that micro-moths have been the official theme of Moth Night in its 20-year existence.
Over the past 30 years, some 28 new species of pyralid have been recorded in Britain, some the result of natural migration, others accidentally imported e.g. with plants for the horticultural trade. Eight of these have already become established in Britain, including Evergestis limbata, which has colonised parts of Devon. First recorded in Britain in 1994 on the Isle of Wight, the first Devon record was in 2004 in Kingsteignton. Since then, this pretty yellow and brown moth has been found all along the Teign Estuary from Teignmouth and Shaldon to Kingsteignton, as well as at Exmouth and around Newton Abbot. How much further has it got? Keep a look out for it for Moth Night and submit any sightings at www.mothnight.info
Aside from new species, there are plenty of native pyralid moths to look out for in Devon this week. These include the Mint Moth Pyrausta aurata, a little purple and gold jewel of an insect found fluttering in the daytime in herb patches and flowerbeds, the distinctive, black and white spotted Small Magpie Anania hortulata and common immigrants such as the Rusty-dot Pearl Udea ferrugalis.
Moth Night activities don’t have to focus on pyralids, of course. There are hundreds of different moth species on the wing in Devon at this time of year and records of any and all of them seen on the three days and nights of Moth Night 2018 are very welcome.
Why not take the opportunity to get out and record moths somewhere new, or introduce family or friends to the wonders of moths? On the Friday night or Saturday morning, you are very welcome to attend the Devon Moth Group field meeting at the Norman Lockyear Observatory near Sidmouth (see Events).
Please submit all your sightings via the online recording form on the Moth Night website, so that we can build up a picture of all the activity and records during the event (all records are subsequently passed on to County Moth Recorders).
The Devon Moth Group Annual Report for 2017 has now been published and distributed to members. The report summarises a record-breaking number of sightings – nearly 64,000 moth records for the year submitted by over 220 Devon naturalists and visiting moth enthusiasts.
Highlights included records of three micro-moth species never previously recorded in the county, Lyonetia prunifoliella, Tuta absoluta and Coleophora alcyonipennella, the best ever year for Clifden Nonpareil and the joint best year for Jersey Mocha, both of which may now have colonised parts of Devon. Other exciting sightings included the first Large Red-belted Clearwing record for 20 years, the second and third ever Devon records of Little Thorn, the second ever record of the immigrant Golden Twin-spot and the first North Devon record of Mere Wainscot since 1960!
Many thanks to everyone who sent in 2017 sightings and to Barry Henwood, the County Moth Recorder, and his team of helpers for collating and verifying all the data! All of the records are shared with the Devon Biodiversity Records Centre and the National Moth Recording Scheme.
Happy New Year from Devon Moth Group!
There are still a few moths on the wing, even at this time of year, including the aptly named Winter Moth (see image below taken on the evening of 29th December 2017), but mainly this is the season for sorting out and submitting all your moth records from the year gone by.
Any sightings of moths in Devon are useful and will, after checking, go into the Devon Moth Group database to increase knowledge and support the conservation of these important insects. All of the data are also shared with the Devon Biodiversity Records Centre, Devon Wildlife Trust and the National Moth Recording Scheme run by Butterfly Conservation.
So if it is not too late for New Year’s resolution, why not make it your mission to submit some sightings. There is information about how to log and send your moth records and, if you get them in before 14 January, your records will feature in the 2017 Devon Moth Group Annual Report. If you can’t make that deadline, just forward your records on when you can – we’ll always be grateful to receive them!
Different moths fly at different times of the year so there is an ever changing line-up of species for moth recorders to enjoy as the weeks go by. While the peak in species richness happens in the first half of the summer, there are plenty of autumn species (and even a few winter specialists) to look forward to in the next few months.
The time of year, therefore, provides an important clue to help with the identification of moths that you might see. While UK field guides to moths give general information about the flight periods of each species, there may be differences between the overall UK situation and the timing in Devon.
Using data from the Devon Moth Group database, Phil Dean has created two really useful resources about the timing (phenology) of moths in the county. One shows the main flight period (in months) for each macro-moth species and the other lists the macro-moth species likely to be on the wing in Devon in each month of the year.
Members of Devon Moth Group have been working hard over recent years to ensure that Devon is well recorded for the forthcoming Britain and Ireland moth atlas. It promises to be a landmark publication and now Butterfly Conservation are offering the chance to sponsor a moth in the new book. All the money raised will be used to publish the atlas.
Each species will have only one sponsor and there are two ways to try to get your name against your favourite species, while contributing to a worthwhile cause.
1. Auction – moth sponsorships are being auctioned online in six batches, each lasting a month. The first auction is live now and you can bid for the right to sponsor species such as Gold Spot, Oak Beauty, Delicate, Four-spotted Footman and even the humble Common Marbled Carpet. Each sponsorship has a reserve price of £25, £50 or £100 depending on the species. At the end of the month, the highest bidder for each species will win the right to sponsor it in their own name or to dedicate it to someone else.
2. Reservation – if you don’t want to take a chance in the aution and have your heart set on sponsoring a particular species, you can reserve it in advance by paying double the reserve price.
You can find out more and see a listing of all the species, when they will be auctioned and which ones have already been reserved on the Butterfly Conservation website.
The first auction will finish on 31 May, so if you want to support this great fundraising cause have a look online soon.
A list of all the species of larger (macro-) moths that have ever been recorded in Devon has been produced and is now available online. The list includes a total of 661 species, some residents others immigrant visitors, which comprises around two-thirds of the total number of macro-moths ever recorded in Britain and Ireland.
South Devon (Vice-county 3) has a total of 657 species recorded, but 26 of these have not been seen since at least 1960, so are either extinct former residents or rare migrants.
North Devon (Vice-county 4) has a shorter list of 575 macro-moth species with 21 not recorded since 1960.
While some moths have been lost from Devon, new species continue to be recorded, either as immigrants from overseas or due to spread from existing populations in neighboroughing counties. Recent additions include Jersey Mocha (Cyclophora ruficiliaria), first recorded in 2011, and Sombre Brocade (Dichonioxa tenebrosa), first seen in 2015, both of which may now be established in the county.
The new checklist was produced by Devon Moth Group Council member Phil Dean, assisted by County Recorder Barry Henwood, using information from the Group’s sightings database and from the 2001 book The Moths of Devon by Roy McCormick.
Devon Moth Group members should have now received their copy of the 2015 Annual Report, which was published in late March.
Drawing on 42,000 moth records submitted during 2015, the Annual Report presents an overview of important sightings, analysis and a comprehensive species list.
Perhaps reflecting the lacklustre weather from late spring to early autumn, 2015 didn’t seem to be a vintage year for our resident moths. However, it was certainly an excellent year for immigration. Major early summer influxes of species such as Striped Hawk-moth, Small Mottled Willow and Bordered Straw, were accompanied by rarities such as Purple Marbled and Many-lined. The excitement continued in July and August with records of Jersey Mocha, Spurge Hawk-moth, Orache Moth, Splendid Brocade and Four-spotted. By the high standards of 2015, September was relatively quiet, but October yielded the first ever Devon record of Tunbridge Wells Gem and rarities such as Flame Brocade, Crimson Speckled and Clifden Nonpareil. And then the year ended on a high, during the unseasonally warm December (17.2°C was recorded at Teignmouth on 16th December), with the first ever county records of Syncopacma polychromella and Cornifrons ulceratalis, as well as sightings of Euchromius ocellea and Spoladea recurvalis among impressive numbers of more common immigrants.
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!
Devon Moth Group’s programme of field meetings for 2015 is now online at Events
We have eight meetings arranged to date, from May to September and spread right across the county from the far south-west coast to the heart of mid-Devon.
Come along and see the amazing moths that live in Devon!
