The small, white pill millipede Trachysphaera lobata has been studied during three visits to the Isle of Wight in 2005 (see report here), 2011 (see report here) and 2012. The millipede was present at the site where it was first discovered in 1984 but attempts to locate further populations were unsuccessful. Insights into the taxonomy and origins of the British populations were possible through collaboration with Dr Thomas Wesener of Zoologisches Forschungsmuseum, Bonn (see report here).
In 2015 a paper was published in the Biodiversity Data Journal looking at the identity and origins of the British populations of the Dwarf Pill Millipede, Trachysphaera cf. lobata.
