Notonecta glauca (Linnaeus, 1758) 
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. Notonecta glauca is found widely in the western half of Nottinghamshire, occurring in ponds, ditches and canals, with no reason to suspect it not to be as common elsewhere in the county. The one llustrated, was netted from a shallow pond at Budby South Forest in August 2020, which also contained Notonecta maculata.
