NEW FOREST CICADA
Common in the rest of Europe the New Forest Cicada is the last of its kind in the UK.
Rarity: Now confined to the New Forest in Hampshire, with some concerns for its continued existence.
Cause of decline: Change in habitat and weather patterns. Extreme isolation of remaining populations.
Cicadas are not insects that are usually associated with the UK, instead, their distinctive calls tend to conjure up images of hot and exotic locations. However, there is one species of cicada that is native to England, the New Forest Cicada. In the middle of the 20th century, over a hundred of these insects were heard calling in one location in the New Forest, which must have been an incredible sound. Sadly, it has now been over 20 years since the cicada was last recorded in England. This means that there is a high chance that the species is now extinct. But we are not giving up hope and are continuing the search!
The New Forest Cicada can be up to 3cm long and has clear visible gold rings and large transparent wings. In their last spring before emergence, the nymphs build a turret like structure from clay and leaf matter on the surface of the soil. These turrets are a reliable means of identifying breeding sites for the species, and can be found at any time between mid-March and late summer, even after the adults have long emerged.
In England, it has only ever been found in the New Forest. It inhabits woodland rides and glades that are in plenty of sunshine. It has also been found in sunny areas between open grass/heathland and woodland with a scrub edge.
Survey for New Forest Cicada, 2017
The New Forest Cicada has always had a limited distribution within the New Forest, Hampshire. No confirmed sightings of the species have been made since the early 1990s, despite extensive searches during the period 1996-2014.
Survey for the species involve searches for pre-emergence turrets in early spring, searches for singing and active adults during the flight period of late May-early July, and searches for evidence of oviposition during the same period and into early autumn.
