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.
