Conservationists from Hampshire & Isle of Wight Wildlife Trust (HIWWT) have announced that the Reddish Buff Moth (Acosmetia Caliginosa), a rare moth species which is only found on the Island, has been recorded for the 1st time in 4 years.
2 Reddish buff moths were found during the Trust’s annual moth survey programme at a sanctuary site on the Isle of Wight. The last adult moth was found in 2019, and the new finds help raise hopes for the future of this endangered moth.
Jamie Marsh, Director of Nature Recovery, Wilder Wight & Wilder Seas, for Hampshire & Isle of Wight Wildlife Trust, has said:
“This is a significant and reassuring find as we were concerned about the status of this endangered species. Covid massively impacted our survey efforts in 2020 and 2021, when only 1 single larvae was found, so to discover that the Reddish buff moth is still persisting is very exciting.”
“It is a difficult moth to survey for and requires a lot of time and effort. It doesn’t readily come to light traps and can easily hide away, so it is very fulfilling to discover 2 individuals. We were getting nervous that the species had been lost so to find it this year, and have it verified by the UK’s leading expert, is a big relief.”
The moth’s last remaining stronghold, which is within a closed sanctuary site for wildlife, contains an ideal mix of its most favoured habitat along with saw-wort (Serratula Tinchoria), the sole larval food plant.
As Jamie explains:
“The Reddish buff moth has a particular habitat requirement in order to survive and flourish. Our intensive management of the reserve has increased pockets of suitable habitat and the required microclimate for this species to thrive.”

The Reddish buff moth is in the family noctuidae, which are also referred as Owlet Moths, and its flight period is from April through to July. Its copper-coloured forewings and pale red hindwings helps it to blend in with its surroundings and attract potential mates. The Reddish Buff is a medium sized moth with a typical wingspan of up to 15mm and weighs just 23mg.
Jamie concludes:
“The Reddish buff moth epitomises the challenges many of our rare species face. Restricted to a single site with specific habitat requirements and a single food plant, it seems to have everything against it, yet it is still persevering, thanks to the hard work of the team, a dedicated group of volunteers and site partners Isle of Wight AONB, Butterfly Conservation, Amazon World and Wildheart Animal Sanctuary.”
The Trust’s remaining focus for the site is to continue to restore and improve the habitat for the moth and other species.
A relative of mine owned the only site where these moths breed on the Island. I won’t say where, but recently walking on the footpath which skirts this large plot, I was dismayed to find it hadn’t been cared for in the same way as which my relatives (sadly both dead now) used to care for it.
I wonder if this is having an impact on this rather boring looking but rare moth.
I hope the new owners of the large and even larger plot (as they have claimed for free an additional plot next to the other) have been instructed on doing the right amount of work to keep the area as the moths prefer.
My rellies were rightly proud of the fact that their garden housed such rarities. Long may such continue.
Someone opened their wallet, always a sign of a moth in the air.
Lol
Quite misleading article. This moth is only found on the island in the UK at present but is locally abundant in many areas throughout mainland Europe and eastward to Siberia.
I’m not trying to downplay this at all, I think it’s marvellous but I swear I have this moth in my bathroom, regularly!? I will try and get a picture of it so someone can check if it is, indeed, this exact type of moth!
