One of four species of Notonecta in the UK, all four of
which are found in Nottinghamshire. They are characteristically large,
backswimming Water Boatmen and their known distribution in the county is
largely due to the recording efforts of Bob Merritt. The one llustrated,
was found in one of the larger ponds at Gedling CP in August 2020.
Notonecta viridis has spread inland and northwards in recent years
and is now much commoner than in the late 1950's, when it was considered
a largely coastal species. |
