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).

Moth Night 2015

This year’s Moth Night celebrations take place on Thursday, Friday and Saturday this week (10-12 September), coinciding with the annual autumn arrival of immigrant moths. Across Devon and the rest of the UK, moth-traps, wines ropes and bedding plants will be deployed by thousands of people keen to see the amazing variety of moths that visit our shores or live year-round in our gardens and countryside.

For some, the focus will be on rare immigrant moths, such as the Golden Twin-spot and Clifden Nonpareil, borne in from hotter parts of Europe and even Africa on warm winds. Immigrant moths will come to moth-traps, but can also be attracted using wine ropes or ‘sugar’ bait, which provide a cheap, simple alternative. And, if you are not lucky enough to spot a rare migrant, spectacular local moths, such as Red Underwing and Old Lady, are also fond of these baits.

The Convolvulus Hawk-moth, on the other hand, has a particular penchant for Nicotiana flowers. Ahead of Moth Night 2015, some moth recorders have stocked their flower beds with Nicotiana ‘Sensation Mixed’, hoping to tempt this mighty migrant to their patch. With its 12cm wingspan, the Convolvulus Hawk-moth is one of the largest moths seen in Britain, yet it is capable of pin-point precision flight as it hovers to drink nectar from the deep Nicotiana flowers using its amazingly long proboscis. There have been lots of Convolvulous Hawk-moth sightings in recent weeks across the South West and right up into Scotland.

Aside from immigrants, there are many stunning autumn moths to admire at Moth Night public events or to search for yourself. Some are beautifully coloured with yellows, oranges and pinks to blend in with autumn leaves. Whatever you find, please log all your Moth Night sightings so that your records can increase our knowledge, inform moth conservation and be shared with County Recorders.

Please also keep your eyes peeled for moths marked with a dab of coloured paint on the wing. These are part of a Moth Night experiment to learn more about how far moths travel. In the days leading up to this year’s event, moths will be marked harmlessly at designated locations, in the hope that some will be caught by recorders taking part in Moth Night. If you find a marked moth, please photograph it and contact the Moth Night website or phone 01326 290287.

Of course you don’t have to do any of these things! Moth Night is what you choose to make it; a perfect excuse to go out and record moths somewhere new, perhaps filling a gap for the forthcoming national moth atlas, or organise an event to introduce people to moths for the first time. Devon Moth Group has two official Moth Night events, both at south coast locations where the chance of seeing exciting migrants is greatest, so why not come along (details of Devon events).

Moth Night is organised by Atropos and Butterfly Conservation, in association with the Centre for Ecology & Hydrology, and an array of prizes are awarded for particularly unusual sightings. Further information about how to take part, public events, bait recipes and more can be found at on the Moth Night website.

Moth Night 2014

Moth Night is the national celebration of moths and moth recording that takes place over three days and nights each year. It’s the perfect excuse to do something special, whether that is recording moths in a new location or organising an event for family, friends or the general public.

This year’s event takes place on Thursday 3rd – Saturday 5th July and the suggested theme is woodland moths. Woodland is the richest habitat for moths, harbouring two thirds of the UK’s larger moths and supporting many rare and specialist species. However, many Devon woods have never been surveyed for moths and this vital habitat faces mounting pressure from urban development, changing management and the arrival of a succession of potentially devastating tree diseases (most recently Ash Dieback).

Moth Night 2014 is a chance to go out into the woods (with permission of course) and record the dazzling diversity of moths that occur there in mid-summer. You don’t have to focus on woodland, though; Moth Night is what you chose to make it. Wherever you record moths for Moth Night 2014, as well as enjoying the spectacle, please submit your moth records via the easy-to-use online recording system at www.mothnight.info – that way you’ll be contributing to improved knowledge of moth distributions and, ultimately, to their conservation. All records will be passed back to the County Recorder too.

There are many public events taking place accross Britain to mark Moth Night and to give people a first hand experience of our marvellous moths. Devon Moth Group is running two such events, at Halsdon nature reserve on Thursday night (3rd July) and at Becky Falls on Saturday night (5th July).

New report shows nationwide moth declines


The State of Britain’s Larger Moths 2013 report published at the beginning of February revealed dramatic declines in moth populations. Analysis of 40 years worth of nightly moth count data from the Rothamsted Insect Survey showed that the total abundance of larger (macro) moths (all species lumped together) has decreased by 40% in southern Britain since the late 1960s. Devon moth recorders contributed to the report through the National Moth Recording Scheme and via several Rothamsted Insect Survey traps in the county.

Two thirds of the 337 common and widespread moth species analysed had decreased in abundance, with many familiar garden moths undergoing severe declines. Numbers of the Small Square-spot decreased by 87% over the 40 years (1968-2007), those of Heart and Dart by 76% and Garden Carpet by 75%. The most severe decline, a 99% decrease, was suffered by the V-moth. This once widespread ‘garden’ moth is now thought to be extinct in Devon and several other counties in southern England.

The main cause of the declines is thought to be the loss of wildlife habitats such as hedgerows and flower-rich field margins as a result of the intensification of agriculture and urbanisation. Reduced woodland management is also believed to be a factor, leading to the loss of open sunny habitats such as glades.

Some species have bucked the trend however. An amazing 27 new moth species have colonised Britain this century and others have increased their previous distributions, perhaps in response to climate change. Here in Devon, we’ve seen species such as the Vine’s Rustic, Jersey Tiger and Dingy Footman become much more widespread in recent decades and new species such as Portland Ribbon Wave become established.

The full report can be viewed or downloaded online from the Butterfly Conservation website.

Get involved in Moth Night 2012

This year’s national celebration of moths and moth recording takes place this week. For three days and nights, from Thursday 21st – Saturday 23rd June, moth recorders and the public will be out and about looking for moths across Devon, and the rest of the UK.

The theme this year is the moths of brownfield sites, so some people will search the abandoned quarries, disused railway lines and other wildlife-friendly brownfield sites in the county. Such sites are important for moths, butterflies and other wildlife, but generally under-recorded and often threatened with redevelopment.

Anyone can get involved to help improve our knowledge of moths in the county and Moth Night 2012 is a great opportunity to make a start. Note down your sightings of moths, day or night, whether from your garden, a brownfield site or out in the countryside, and submit them to Moth Night via their easy-to-use website.

You can also come along to one of the events taking place in the county, where experts will be catching moths, to find out more about these beautiful insects.

For a list of events that are taking place, as well as how to submit your sightings, visit www.mothnight.info

Moth Night 2012 is organised by the wildlife magazine Atropos and the charity Butterfly Conservation, in association with the Centre for Ecology & Hydrology.
