Massive Moths On The Move – Moth Night 2015 10 – 12 September 2015
Back gardens across the UK will be baited with alcohol and sugar later this week as part of a cunning bid to lure in a massive continental moth whose tongue is longer than its body.
Moth-lovers are hoping to attract the palm-sized Convolvulus Hawk-moth into their gardens as part of Moth Night, an annual event led by wildlife charity Butterfly Conservation.
With a 12cm wingspan, the Convolvulus is one of the largest moths found in Europe and migrates from North Africa, yet it is capable of pin-point precision flight as it hovers to drink nectar from deep tubular Nicotiana flowers using its amazingly long 7.5 cm proboscis.
Moth night is all about raising awareness of the UK’s moth species, many of which have suffered huge declines during the last 40 years, with three species becoming extinct in the last decade.
This year the theme is on migrant species like the Convolvulus, as sightings will help build a clearer picture of moth migration into the UK and the effects of climate change on UK moth populations
Butterfly Conservation’s Head of Recording, Richard Fox, said: “It has already been an amazing year for moth immigration and such activity usually peaks in early autumn. With migrants such as the massive Convolvulus Hawk-moth mixing with beautiful home-grown autumnal species, Moth Night is a great opportunity to discover the hidden wonders of our nocturnal wildlife at a public event or even in your own back garden.”
Other spectacular immigrants to look out for include Death’s-Head Hawk-moth and Crimson Speckled along with the Vestal, which are all borne in from hotter parts of Europe and even Africa on warm winds.
Atropos – the UK journal for moth enthusiasts – helps to organise the event with Butterfly Conservation. Its editor, Mark Tunmore, said: “We will be remaining extra vigilant at Atropos’s headquarters in Cornwall over the Moth Night period. For many decades this area has been a famous location for visiting moth enthusiasts, hoping to see some of the rarer visitors to our shores at this time of year. One of the great things about moth recording is that immigrant species have the potential to turn up anywhere in the UK so you don’t have to live in the south or even on the coast to have a chance of observing something unusual and I encourage everyone to get involved, wherever they might live.”
Immigrant moths will come to moth-traps, but can also be attracted by hanging out ropes soaked in wine – a practice known as wine roping.
Another moth attracting technique, known as sugaring, involves painting a mixture of sugar, syrup and beer onto a post or tree trunk.
Moth recorders at UK migration hotspots have also been colour marking some moths caught in the weeks leading up to Moth Night and the organisers will be asking people to keep an eye out for marked moths in the hope that it might reveal more information about insect migration.
Moth Night 2015 runs from 10-12 September and will include night time moth trapping events across the UK www.mothnight.info
If anyone finds a marked moth they should contact www.mothnight.info
Moth Night 2015 is organised by Atropos and Butterfly Conservation in association with the Centre for Ecology & Hydrology, with the aim of encouraging recording and raising the profiles of moths amongst the public. The annual event was founded by Atropos in 1999.
