As part of the Findhorn Hinterland Trust’s ongoing work to identify the biological diversity that occurs on the 35 hectares of land that we are responsible for managing, we commissioned a survey of the true bugs, or Hemiptera, and barkflies, or Psocoptera, on the site in the summer. This was carried out by Joe Botting, one of the UK’s leading experts on these groups of insects, over a period of three days at the end of July.
There are over 40,000 species of Hemiptera known to science, of which almost 2,000 have been recorded in the UK, and those include some well-known species such as the common froghopper (Philaenus spumarius) and various shieldbugs. By contrast, there is much less diversity within the Psocoptera, with a total of just 100 species having been recorded throughout the UK. Given the small size of the Hinterland site and the limited range of habitats we have on it, we did not expect to find a significant proportion of the UK species here, but Joe’s survey did result in the identification of 104 species of true bugs and 6 species of barkflies.
The occurrence and distribution of these insects varied across the different habitats on the site, with the old plantation of Corsican pines being the poorest in terms of both species and the actual numbers of bugs, whilst the dune slack area to the north of the woodlands contained both the greatest diversity and a number of scarce and interesting species. I accompanied Joe for most of the time he was carrying out the survey and was able to photograph quite a number of different bugs, including some of the scarce species.
Of particular note were a leafhopper (Gravesteiniella boldi) which occurs in coastal sandhills with marram grass and is very rarely recorded – this was the first record for Scotland, according to the National Biodiversity Network (NBN) Atlas – and a planthopper (Muirodelphax aubei), which has a mainly southern distribution in the UK (this was only the second record for it in Scotland on the NBN Atlas).
Other species of particular interest included a planthopper (Macropsis fuscula) that has only been found once before in Scotland, at Gretna Green, and the blue shieldbug (Zicrona caerulea), for which this was the second most-northerly record in the UK. A poplar-associated leafhopper (Populicerus laminatus) that was found during the survey has only been recorded in the Highlands once before (on Trees for Life’s Dundreggan Conservation Estate in Glenmoriston), while this was the first Scottish records for a leafhopper (Edwardsiana crataegi) that is relatively common in the south of England and Wales.
The survey also recorded a lot of common and abundant species, including the parent bug (Elasmucha grisea). This is a shield bug that is named for the behaviours of the females in sheltering their eggs and the young nymphs for some time after they have hatched, to protect them from predators. This is a relatively rare example of parental care amongst insects! I’ve found parent bugs with their young in July in most years on the birch trees near the central wind turbine, and they were there again when Joe was on site.
This survey adds considerably to our knowledge of the diversity of true bugs on the Hinterland area. This is important both in and of itself, and also because of the fact that insects are almost certainly the most diverse groups of organisms on the land we care for (being much more numerous and diverse than birds, mammals, trees etc), with the Hemiptera and Psocoptera being important components of the insect community. Although bugs are not active in the winter, I hope the survey and this report will encourage Hinterland members and supporters to look out for these interesting and diverse insects after they emerge again next spring!
With special thanks to Joe Botting for carrying out the survey, and for doing so at a discount from his usual rates.

Chair’s Report – Autumn/Winter 2023
The tail end of the year has been a mixture of blue sky days, wind and wet as the sounds of the thousands of geese returning to the Bay are heard. The work of the trust proceeds from strength to strength with some new projects and possibilities raising their heads and others just carrying on in the background.
Walking the land the other day I had a lovely and fulfilling feeling that arose from seeing the land being so well looked after and valued by the many – new trees well protected and staked, new glades in the woods starting to sprout regenerating tree seedlings, ponies contented in their field, maritime heath areas cleared of invasive species, a flow of chatting children and adults proceeding to their fire and bench area as part of their Friday morning Fledglings gathering, the Conservation Hub there as a beautiful structure in the woods and working so well as a base for the conservation work and… So many things to be thankful for. Much of this good work would not happen without you as members over the last fifteen plus years being out there the last Saturday of each month putting in your love and effort during our regular work parties and of course the sterling work of our Land Manager Kajedo Wanderer who is now the backbone of the good work that happens on the land – thank you Kajedo, thank you all!
Ongoing projects are progressing such as the large scale Dune Restoration work planned for next year which looks like it will involve working collaboratively with neighbouring landowner the Findhorn Dunes Trust (See Sean Reed’s update elsewhere). It also feels good that we are working with the charity Moray Supports Migrants and Refugees (MSMR) to put in place four work party events combining getting asylum seekers in Moray together with regular trust members to carry out brash clearance on the land we look after to the north of Wilkies Wood. MSMR has secured funding from the charity Migrant Help for transport for these events, the Findhorn Foundation will be supplying the bus, Volunteering Matters through their Action Earth grant will be contributing by enabling the purchase of tools and gloves and the FHT will be organising the work this end – a magnificent and positive collaborative venture that we trust will be supported by our members and will fulfil both our conservation and local community building charitable purposes.
Other projects that are progressing include the erecting of the new pony shed from the recycling of the old food buyers office that we saved when clearing the sanctuary site, an offer is now in to help secure the acquisition of Duneland Ltd wild land and the long overdue project of painting the tractor trailer is happening with the help of Louna our new long term Swiss volunteer. Louna has been a great asset and is looking to be with us until March staying in the Shepherd’s Hut and working half time on the land ( see the interview elsewhere which gives a little more background.
I have also been pleased to have Roy Simpson lead another Sharing Nature with Children workshop on the land and next year would like to see this promoted more widely so that more people within the local community and beyond can benefit from this inspiring way of learning more about the nature that surrounds and nourishes us every day.
We are aware of upcoming events such as our annual Christmas tree happening up at the Woodland Shelter this year on the 2nd December from 11am until 2pm and in the new year we hope to have a fundraising event which involves the showing of the film Alan Watson- Featherstone has been involved in called ‘When the Bough Breaks’. In the coming months we will also be working with round wood crafts personHenry Fosbrooke finishing the preparation of the columns and beams for the new sanctuary as part of the FHT’s contribution to this important community project.
Thanking the whole team that help make the good work of the FHT possible – together with each person leaning in a little we can make miracles happen! Wishing you all a pleasant and safe festive season.
Blessings,
