Records generated from moth trapping with light traps by amateurs naturalists all over the UK is the main way conservationists can understand how moth numbers are changing. N.B. The moths are subsequently released unharmed. While many enthusiasts moth trap year round, Moth Night is an annual celebration of moth recording throughout Britain and Ireland aimed at raising awareness of moths among the general public. It is organised by Atropos, Butterfly Conservation and the Centre for Ecology & Hydrology. Usually held in the summer months, this year it is being held from 26-28 September to target the spectacular (in appearance and in name) Clifden Nonpareil, and other late summer migrants moths.
The records generated from Moth Night, and from all other moth trapping is useful to conservation. While declines in large and ‘charismatic’ species are regularly reported in mainstream media, insects are often forgotten. For example in the UK, Butterfly Conservation reported habitat specialist butterflies (26 species) to have declined by 77% since monitoring was started in 1976, while more generalist butterflies (24 species) decreased by 46%. This is unfortunately also seen on a global scale, with 40% of insect species declining, and a third classified as endangered. It’s also not just the numbers, but the biomass, with the total mass of insects falling by 2.5% a year – suggesting an unsustainable future for populations.
The more we know about insects, the more we can do to try and save them. Below are a few images of moths recently seen within and around the North York Moors, including our own brilliant Clifden Nonpareil – the first time this moth has been seen in Yorkshire for many years.
