Cicadetta montana

• Betula pendula (European white birch) • Betula pubescens (downy birch) • Corylus avellana (common hazel) • Crataegus monogyna (common hawthorn) • Fagus sylvatica (European beech) • Pteridium aquilinum (northern bracken fern) • Quercus robur (pedunculate oak) • Ulex europaeus (common gorse) ==Taxonomic history==

In 1772, Scopoli described and named the type specimen from Slovenia as Melampsalta montana, and this was later changed to Cicadetta montana. It has turned out to be not a single taxon, but a complex of closely related species distinguishable by their songs. Using this method of differentiation, at least 10 species have been separated from the complex. Classification by calls has led to three main groups being proposed which largely correspond with the clades suggested by DNA analyses – one new species not fitting in the proposed scheme. Synonyms • Melampsalta montana Scopoli, 1772 • Cicadetta flavofenestrata Goeze, 1778 • C. schafferi Gmelin, 1780 • C. pygmaea Olivier, 1790 • C. dimidiata Fabricius, 1803 • C. anglica Samouelle, 1819 • C. parvula Walker, 1850 • C. saxonica Hartwig, 1857 • C. megerlei Fieber, 1876 • C. longipennis Fieber, 1876 ==New Forest cicada project==

C. montana has not been seen or heard anywhere in Britain since 2000. In 2013, in an attempt to locate remaining specimens, developers have written application software for smartphones, enabling users to listen to sound frequencies beyond the normal human range. Up to December 2015, over 3,000 people had downloaded the ″Hunt for the New Forest Cicada app″ without success in Britain, although the app has recorded the insect in Slovenia. From 2016 onwards, 100 autonomous acoustic monitoring devices were to be deployed each year throughout the New Forest. C. montana also disappeared between 1941 and 1961, so their current absence may be part of a cycle. In 2024 a project to re-introduce the species to the New Forest was launched by the Species Recovery Trust. The project will involve capturing individuals from the Idrija region of Slovenia, with some to be captive bred and others released into a series of carefully monitored locations. ==References==
