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.
