Annual report for 2019 published

The Devon Moth Group Annual Report for 2019 has been published and distributed to Group members. It summarises 80,000 moth records (c.17,000 for micro-moths and c.63,000 for macro-moths) for the county last year from 286 recorders. The records have been compiled and verified by the County Moth Recorder, Dr Barry Henwood, and his fantastic team: Phil Barden, Darryl Rush, Phil Dean, Kim Leaver and Bob Heckford. Four new micro-moth species were recorded in Devon during 2019: Ectoedemia heringella, Parectopa ononidis, Monochroa palustrellus and Cochylidia implicitana. In addition, the first modern day record of Small Ranunculus was made when the moth was spotted in a pedestrian subway in Exeter. All the records will be shared with the Devon Biodiversity Records Centre and the National Moth Recording Scheme run by Butterfly Conservation. Many thanks to all the recorders who submitted sightings of moths in Devon during 2019.

The Pug Moths of Devon

Among the larger moths, the pugs are notoriously tricky to identify. Some species are very distinctive, being boldly patterned and coloured, but others are definitely a challenge. Help is at hand, thanks to the publication of a new book, The Pug Moths of Devon by Phil Dean of Devon Moth Group.

Although not primarily intended as an identification guide, the new book will certainly help. It contains a detailed account of each pug moth recorded in Devon, including taxonomy, distribution maps, flight charts, and a colour photo of the adult (see example below). The Pug Moths of Devon is based on 34,000 records extracted from the Devon Moth Group database and is published in A4 format with 64 pages.

Copies cost £7.00 (+ £3.00 p&p) and can be obtained by emailing [email protected]

One Million Moth Records

Devon Moth Group is celebrating the collection of one million moth sightings across the county.

The Group, which collects and checks all sightings of moths and their caterpillars reported in the county, has amassed the impressive total since its formation in 1997. The records date back to the mid-19th century and provide a long-term view of the changing wildlife of Devon.

The landmark millionth record was of a V-Pug, a small green moth with a characteristic black v-shaped mark on its wings, which was spotted by Devon Moth Group member Kevin Johns in his Newton Abbot garden.

Moth recording plays an important role in conservation as the information gathered shows which species are flourishing and which are in danger. The sightings then identify parts of Devon where threatened and declining moths still remain so that conservation action can be targeted effectively. All of the records gathered are shared with the Devon Biodiversity Records Centre, Devon Wildlife Trust and the UK-wide National Moth Recording Scheme.

Around 1,700 moth species have been recorded in Devon, some two-thirds of the total for Britain. These include nationally important species such as the rare Scarce Blackneck, Beautiful Gothic and Devonshire Wainscot.

The V-Pug, which has the scientific name Chloroclystis v-ata, is a widespread species in Devon. Its unobtrusive caterpillars feed on the flowers of a wide variety of plants including Bramble, Dog-rose, Elder, Hawthorn and Hemp-agrimony. V-Pug moths are often found in gardens, where they are beautifully camouflaged resting against mottled foliage and algae-covered bark.

Gardeners can do a great deal to help moths, including planting a variety of moth-friendly flowers for nectar, especially native plants, keeping a few areas rough and untidy, and avoiding the use of insecticides wherever possible.

Kevin Johns, who has been a regular contributor to the Devon moth database, was delighted to learn that his V-Pug record turned out to be the one that passed the million mark. He said that it was “a brilliant surprise, really quite special”. Being retired, Kevin has many interests, moths being just one of them. He describes his garden as a small courtyard with a few shrubs and flower beds, but importantly says it is close to mature woodland which means that a good number of moths are attracted to his light-trap to be noted and released unharmed. “I’m really pleased with what I get”, he added.

All the records submitted by volunteers in Devon are collated by the County Moth Recorder, Barry Henwood, who in turn passes them on to the Devon Biodiversity Records Centre whose manager, Ian Egerton, explains, “Devon Biodiversity Records Centre is a partnership-led organisation set up to gather information on Devon’s species and habitats. We ensure that biodiversity information feeds into decision-making locally and nationally, and over the last 25 years, our efforts have been underpinned significantly by the county’s huge network of volunteer recorders. Their passion and interest in specific species has created much of the data we now hold, and the level of knowledge and expertise within groups such as the Devon Moth Group, is key to supporting a conservation sector which could not operate without them”.

Sadly, moths, like so much of our wildlife, are in serious decline. For example, populations of the V-Moth (not to be confused with the V-Pug) have crashed by 99% in Britain since the 1960s, while the stunning Garden Tiger, once a familiar sight to naturalists, has slumped by 92%.

How to get involved in moth recording

Rare Bedstraw Hawk-moth caterpillar spotted

A rare Bedstraw Hawk-moth (Hyles gallii) caterpillar was spotted in an Exmouth garden on 1st October. This impressive caterpillar, which can grow to 8cm in length, was feeding on Fuschia leaves. Adult moths of this species are scarce immigrants to Devon from continental Europe and two had been seen in early August, one in Chudleigh and the other in Seaton. Given the timing, the Exmouth caterpillar is probably the offspring of a female Bedstraw Hawk-moth that arrived on the south coast as part of the summer influx. (Photo by Jan Gannaway)

2019 field meetings

The programme of Devon Moth Group outdoor meetings for the coming months is now available on the Events page.

Eight field meetings have been organised by our volunteer leaders and partner organisations. All of the events involve night-time moth trapping and are a great way to see new species, to experience the excitement of nocturnal moth recording in the company of experts and to help improve knowledge of the distributions and changing fortunes of Devon’s moths.

Moth Night is here

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).

Record year

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.

Records resolution

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!

What is flying when?

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.

Flight period information about Devon moths can be found here.
