On 17th March 2018, Director Chris Cathrine presented the results of Site Condition Monitoring invertebrate surveys at Sites of Special Scientific Interest (SSSIs) in Tayside, at the Tayside Recorders’ Day, in Perth. Some of the results of these surveys, completed between 2011 and 2017 under contract to Scottish Natural Heritage (SNH), have not been made publicly available before, other than as records on NBN Atlas.
Caledonian Conservation Ltd has completed Site Condition Monitoring of invertebrate features for 56 SSSIs in Scotland between 2011 and 2017 under contract SNH. Of these SSSIs, five were located in Tayside: Barry Links (2011), Black Wood of Rannoch (2013), Den of Airlie (2015), Dollar Glen (2013), and Methven Woods (2015).
Among the stand out finds were the rediscover of the extinct flutter-wing fly Palloptera laetabilis and finding other rare invertebrate such as the lichen running-spider (Philodromus margaritatus).
The conference presentation and article in the Tayside Recorders’ Bulleting which includes the conference proceedings can be downloaded via the Caledonian Conservation Ltd publications page.

While surveying for flies and butterflies during Site Condition Monitoring at Morrich More Site of Special Scientific Interest (SSSI) in 2015, Director Chris Cathrine made a surprising discovery when a big female Northern bear sider (Arctosa cinerea) ran on to his sweep net!
This is not only the most northerly record for the Northern bear spider in the UK, but is also the first documented example of the species using sandy habitats – in this case on a stabilised dune system. Although it has been found to use this habitat for some parts of its life cycle in Europe, it is typically found under stones in shingle in the UK.
You can read more about this discovery in an article in the latest issue of the latest issue of the Newsletter of the British Arachnological Society. The article is also available to read here, via the Caledonian Conservation Ltd publications page.

A rare flutter-wing fly, Palloptera laetabilis, not seen in the UK for over 100 years has been found at Den of Airlie Site of Special Scientific Interest (SSSI), a woodland in Angus. This is also the first time this fly has ever been found in Scotland.
The rare fly was presumed to be extinct, but was found during site condition monitoring surveys completed by Caledonian Conservation under contract to Scottish Natural Heritage (SNH) in 2015. The discovery has since been confirmed and published by Steven Falk (the fly expert on the project team) in the most recent issue of Dipterists Digest.
Den of Airlie SSSI is only the fifth site that this species has been recorded at in the UK, and the only one in Scotland. The other four sites are all located in England, with the last record being from Oxfordshire in 1907.
Chris Cathrine, Director of Caledonian Conservation and project leader for the 2015 invertebrate site condition monitoring project said: “Finding a species last recorded over a century ago is very exciting. That this is also the first record for the species in Scotland makes this all the more special. We found a great number of rare species during our surveys across Scotland. While Palloptera laetabilis is undoubtedly the most exciting, we hope to publish records from all 25 sites, including the Isle of Rum, in the future.”
The invertebrate records collected by Caledonian Conservation during these surveys (including Den of Airlie SSSI) are available on NBN Atlas at: https://registry.nbnatlas.org/public/show/dp4

A new paper on Donaciinae (aquatic leaf beetles) in Britain and Ireland has been published in The Coleopterist - a journal focussing on beetles in the British Isles. Chris Cathrine (Director (Ecology) at Caledonian Conservation Ltd) worked with Garth Foster (The Aquatic Coleoptera Trust, and lead author) and Brian Nelson (Department of Arts, Heritage and the Gaeltacht) to produce this update on these fascinating beetles.
The paper includes several new vice county records, and draws on a range of sources including two Site Condition Monitoring reports for Sites of Special Scientific Interest (SSSIs) in Scotland, completed by Caledonian Conservation Ltd under contract to Scottish Natural Heritage (SNH).
The most recent Site Condition Monitoring report cited in the paper, and other interesting documents, are also available from our publications page.
