The purpose of Dorset Moths is to bring together all those interested in moths in Dorset, and to promote the importance of moths as an indicator of biodiversity and habitat health.
Dorset is fortunate in having diverse unspoilt habitat, and a fine list of resident moth species; also being on the central South coast it is well placed for immigrants, irruptive and pioneering new species for Britain. Some of the coastal headlands are magnets for moths and trappers alike, with a small but hardy number of resident moth-trappers spread throughout the County. See here for information on the County.
Please note that the summary data and record details presented on the Species Accounts pages of this website are correct to 2011, and have not been updated with more recent records. The status and distribution of some Dorset moth species have changed significantly since that date and a number of new arrivals have been added to the County list. The best way to present up-to-date data for the County is currently under discussion.
DORSET MOTHS (VC9) MACRO-MOTH REPORTS 2010-2016
18 May 2020: Following on from the publication of the 2019 Annual Report, Les Evans-Hill (Dorset macro-moth county moth recorder 2010-2016) has produced summary macro-moth reports for the seven years running from 2010 to 2016. We are indebted to Les for his work during this period.
19 May 2020: Revised versions uploaded with added weather data.
19 June 2020: Further revised versions uploaded to website. Les Evans-Hill comments: "Due to errors in the MapMate database queries used to prepare the original reports, some data in those reports were subsequently found to be inaccurate. These errors have been rectified, new reports generated and are presented here. Apologies for any inconvenience.”
The reports can be found at the new Annual Reports page on this website - link here.
DORSET MOTHS (VC9) ANNUAL REPORT 2019
6 May 2020: The verification team is pleased to announce the publication of the Dorset Moths (VC9) Annual Report for 2019 (online only). A pdf version of the document (918 kB) can be downloaded here.
The Report contains the year's highlights and lists significant macro and micro-moth records for the vice-county. Migrant moth highlights are also included, as well as overall recording statistics and a number of other articles.
The verification team would like to express its thanks to all of the recorders, both resident and visiting, who have submitted their Dorset moth records for 2019 - many of which are featured in the Report.
Moth recording and Coronavirus Covid-19 - UPDATED ADVICE 14 May 2020
Please see this advice to moth recorders from Butterfly Conservation.
Recording and Verifying Dorset Moths
Dorset moth records are now verified by a group of volunteers. Dr Phil Sterling leads as the County Micro-moth Recorder, while the role of Macro-moth recorder is being shared by a verification team co-ordinated by the Dorset Environmental Records Centre (DERC) comprising: Adrian Bicker, Terry Box, Paul Butter, Peter Forrest, Julian Francis, Mike Hetherington, Tom Morris, Jack Oughton and Phil Sterling.
The best way to submit records is through Living Record www.livingrecord.net, which is the website that the verification team are using to review the records. However, all records are welcomed (spreadsheets for preference): these can be sent to . General queries about the recording arrangements can also be sent to that address. Guidance on how to format spreadsheets for submission to Dorset Moths can be found here. Advice on how to treat aggregate species when submitting records by spreadsheet or Living Record can be found here.
The Dorset Moths website and Facebook group https://www.facebook.com/groups/dorsetmoths/ are active for postings of latest sightings and moth-related chat.

BOX-TREE MOTH SURVEY - HELP REQUIRED
Saoirse Pottie, PhD student from Royal Holloway, University of London is looking for moth recorders to help with two research projects. The first requires information on sightings of box moth and the second is looking for new and historical usage of pheromone lures - further information is detailed below.
The first project is looking at the distribution of the three different colour morphs of the box moth in the UK. Variations in colour can be associated with habitat, disease resistance, susceptibility to insecticides, reproductive success and predator avoidance. I am interested in understanding if the distribution of these morphs in linked to its establishment. The survey is asking you to date and record the number of each morph you sight. If possible, information on the sex of each morph would also be very valuable. Any historic photographs or information would be a bonus!

The second project is looking at establishing the distribution and usage of pheromone lures in the UK. Pheromone trapping has the potential to shed light on species under-recorded by other trapping methods and could prove a valuable tool for conservation. The survey will help to quantify the value of pheromone lures and better understand the species true distribution. The data can be used to help predict other locations where the species may be present. Any additional information on how often these locations have been visited and other unsuccessful locations tested would greatly improve the accuracy of these predictions.
If you have ever put out a pheromone lure (successful or not), please follow the link below to fill in the quick survey and help us understand how pheromones are used across the UK.

Dorset Moths Autumn Meeting 2019
The Autumn Meeting 2019 was held at Tolpuddle Village Hall on Saturday 12 October 2019. Some 40 local moth recorders attended and heard the following presentations:
- Verification Team update (Mike Hetherington (slides here) & Alison Stewart DERC (slides here))
- The Undiscovered Undercliff (Paul Butter) - slides here and speaking notes here
- Moths of Poole Harbour (Chris Thain & Abby Gibbs)
- Moth Research in Goricko Nature Park, Slovenia (Peter Davey)
- Weymouth Relief Road Verges (Phil Sterling) - slides here and see Phil's 2019 update here
- Using Living Record (Adrian Bicker) here
A discussion about future directions for the Dorset Moth Group reached the following conclusions:
- A preference to keep the Group informal.
- A wish for some field meetings to be organised under the public liability insurance of another organisation.
- The production of an annual report and/or electronic newsletter.
- The organisation of an early Spring meeting. Suggested topics were: pug identification and a Living Record teach-in session.
Many thanks to all who organised and attended the event – and special thanks to Phil Sterling who chaired the meeting and Julian Francis who arranged the venue and the excellent refreshments.
An archive of past Dorset Moth Group newsletters has been added to this website - see the Newsletters
page. At present this includes newsletters from 1994 to 2006
(added January 2020), containing a wealth of information about the early days of Dorset moth recording and including some fascinating articles. More will be added in due course.
The success of the National Moth Recording Scheme mapping the macro-moths has generated interest in mapping all moths within the County, including the micro-moths for the first time, here. It should be acknowledged that the maps and species accounts are provisional, incomplete, in some case unverified, and only take into account records that have been submitted to the County Moth Recorders. Some of the older records dates and sites are a bit vague, sometimes just a year and a 10km square. It is hoped that having this resource available will stimulate some recorders to send in their records for the first time, and that past records are captured too. Peter Davey’s excellent macro-moth accounts are already included, and new information will be added in due course. This is very much a work-in-progress, and the summaries are still being updated to reflect the content.
See Moth Recording for information on submitting records, and Dorset Moth Status for a list of species. The Species Accounts brings together status, distribution, phenology, photos and general information on each species, and by registering and logging on you have the ability to click on dots on the map to get individual record detail.
When faced with an unidentified moth, try Common Species for details on the 25 most common species recorded in this week, with photos and links to the Species Accounts. There is an option to see a list of all species recorded in this week too.
