Greater Water boatman – Notonecta glauca

This is a tadpole’s eye view of a greater water boatman that has its home in our outdoor aquarium. Notonecta glauca is one of several UK species of Greater Water Boatman and a tadpole would do well to be wary – these ‘backswimmers’ as they are known in the US, are carnivorous and will happily prey on tadpoles, small fish or other aquatic insects.
Visually similar, lesser water boatmen are not closely related and characteristically swim ‘the right way up’.
The aquarium has been a fascinating experiment through this spring and I will post more on its creation and the pond-life that now populate it in coming weeks.
