Findhorn dunes are widely recognised for their unique habitat and specialist biodiversity, particularly their lichen assemblages. However, what is less widely known is the importance of the dunes for moths. Many scarce duneland specialist species make Findhorn their home, such as the Lyme Grass moth Longalatedes elymi, the Coast Dart Euxoa cursoria, or the enigmatic and beautiful Portland Moth Actebia praecox. However, there is one species for which Findhorn is far more important.
Scythris empetrella is a small (4-5mm long) moth in the Scythrididae family. At first glance it appears unremarkable, and may not be recognised as a moth due to its lack of willingness to fly – the adults prefer to make short jumping flights off of the sand almost akin to the motion of a sandhopper. However, on closer inspection the moth reveals itself to be an attractive charcoal grey with a variable degree of whitish irroration (figure 1).

In Scotland, Scythris empetrella is only found at two sites: Findhorn Dunes, and Cuthill Links on the Dornoch Firth. The moth is abundant at Findhorn but has only been found once at Cuthill, making Findhorn the most important site for this species in Scotland. Outside of Scotland the moth is found at a handful of sites in the New Forest and on the Dorset heaths in England, and globally is confined to sand dunes and similarly sandy habitats along the coasts of the North and Baltic Seas.
What makes Findhorn so special for this species is unknown, but it might have something to do with the feeding habits of its caterpillar. The caterpillar eats Crowberry (Empetrum nigrum) and Heathers (Erica and Calluna), feeding from within a sand-covered tube of silk which extends from within the sand up to the green leaves of its foodplant. This tube no doubt conceals the caterpillar from predators, but also probably acts as a conduit along which the caterpillar can move at great speed backwards or forwards to escape danger.
Figure 2 – Scythris empetrella habitat, Findhorn Dunes 28th June 2022. The left-hand image shows the site where most adults were found, amongst loose wind-blown sand and heather. The right-hand image shows another site where I found adults, but never in such densities as observed at the previous site.
At Findhorn the adult moths are most abundant in parts of the dunes where green heather stems poke through loose, wind-blown sand (figure 2, left). One can also find them further back from the coastline on wind-sculpted heather hummocks (figure 2, right) but in much lower densities. I would speculate that the swamping of heather and crowberry stems by wind-blown sand allows the caterpillar to access green growth otherwise inaccessible when the plants grow high above the sand. Findhorn is relatively unique amongst the Moray dune systems for having good quantities of heather and mobile sand, which might explain the dunes’ importance for this species.
That said, the moth is easily overlooked and it is very plausible that it may be lurking in other sandy habitats along the Moray Firth. I have failed to find it on the Culbin Bar, but one good place to search for it may be in open parts of Culbin forest where heather grows on loose sand. If anyone spots the moth, or sandy tubes on the heather anywhere along the Moray Firth this summer, I’d ask them to please email me at [email protected] with a date on which the tubes or moth were seen, a six-figure grid reference, and a photograph.
I would like to thank Jonathan Caddy for the invitation to write a piece on this moth, and Fay Wilkinson for providing details on the Cuthill record for this species.

His role involves collecting and identifying moth specimens, and then passing them on to the sequencing team who generate the data. The project is non-commercial, and all data is publicly available.
May Day Celebration in the Findhorn Hinterland
by Linde de Vroey
On the first of May, I had the chance to join the Findhorn community when they came together at the Ceremonial Burial Ground in Wilkies Wood to celebrate May Day. I was immediately struck by the brightness of all the colors: the beautiful yellow, white and pink flowers in the crowns, the dark green and gold embroidery of the ceremonial costume, the bright green color of the grass, and the May pole with shiny ribbons in every color of the rainbow. Though the weather wasn’t as bright as the flowers, the people who joined surely were, and there was a happy atmosphere in the air. After all, we were here to celebrate spring!
We started the day by weaving crowns of willow, ivy, flowers and ribbons – a truly enjoyable and creative activity, and of course everyone needed to look their best for the actual celebration. When all the children (and lots of adults) had their crowns ready, we gathered together in a circle for the ceremony. Draeyk guided us all in a beautiful moment of reflection, to thank the land and wish for peace. And then it was time for the highlight of the day: the dance around the MayPole! I had never seen a May day dance before, and I was mesmerized by all those beautiful ribbons almost magically weaving a pattern together, just as a result of the dancing. As I stood there, singing and clapping and watching, I found it truly beautiful to see this age-old dance re-enacted; not as some old relic of the past, but as a very living moment – and as a lot of fun too! It reminded me of something I read by the Potawatomi writer Robin Wall Kimmerer, about the importance of sustaining ceremony as a community:
“Ceremony focuses attention so that attention becomes intention. If you stand together and profess a thing before your community, it holds you accountable. Ceremonies transcend the boundaries of the individual and resonate beyond the human realm. These acts of reverence are powerfully pragmatic. These are ceremonies that magnify life.”
On May Day in Findhorn, I could see these acts in action. By honoring tradition, we honor the history of a place, the people and beings who came before us and who cared for this land, so that we could now make a living here. By giving thanks to the land, we sustain our relationship to the land. By dancing together, we weave a community with the people and the place and all beings that live here. But the truly wonderful thing is that by celebrating together, caring together, dancing together, we don’t even have to think about it. We live it.

I am a philosopher and a PhD researcher at the University of Antwerp, Belgium. My research focuses on the intersection between ecological restoration, rewilding and cultural heritage. I am very interested in place-based and community-guided approaches to restoration; and in the role that cultural tradition, stories, language, ceremony and history can play in restoring the relationship between people and the natural landscape. I first came to the Park Ecovillage, Findhorn last April in light of my research project. There I encountered a unique place where the community has carried out pioneering and inspiring work, not only restoring the land, but also restoring and sustaining an intimate relationship between the community and the land.
