Cicones undatus is a small (2.5-3.5mm) beetle,
which was first recorded from Stoke Bardolph in 2004 by Adrian Dutton,
then at Attenborough NR by Tim Sexton in
January 2017 (who supplied us with the lower two photographs) and by
ourselves at Wellow Park in April 2019. A relatively recent colonist of the UK, it
was discovered at Windsor Great Park in 1984 and has
since been recorded from other south-eastern counties. It is believed to be associated
with Sooty Bark Disease of Sycamores, caused by the
fungus Cryptostroma corticale. |
