Fantastic news! The AWT have recorded a brand-new species for Alderney: the Dark Crimson Underwing!

This is a beautiful species of moth, with its name coming from the red patterning on their hindwings which are flashed to startle any potential predators. Their forewings also have an interesting pattern, made up of a variety of brown and cream shades, and they can reach a wingspan of up to 70 mm. Their Latin name is Catocala sponsa, with ‘Catocala’ meaning ‘beautiful below’ and ‘sponsa’ coming from the words for ‘bride’ and ‘fiancé’.

Dark Crimson Underwing

On Alderney, the Dark Crimson Underwing was recorded on Saturday the 22nd of July at Essex Farm, during one of our weekly Moth Mornings. We were absolutely delighted by the sight and, while unsure at first whether it was a new species for Alderney, we knew it was definitely special. This being the first record was later confirmed by looking through collaborative moth data.

To make this wildlife spot even more incredible, the Dark Crimson Underwing is considered a ‘Priority Species’ in the UK, making it one of the country’s rarer moths. This may be due to the species reliance on mature and ancient trees (especially oak) as a food resource and breeding site.

During our Moth Mornings, not only do we showcase the island’s fantastic moths to members of the public who attend, but also record the species we find. This data then goes towards the Garden Moth Scheme, a national citizen science project which aims to monitor any changes in moth populations overtime.

Our Moth Mornings take place at Essex Farm every Saturday at 8:00 AM through the spring and summer season (this is weather dependent) and everyone is welcome to come along and join in!
