Please note that the NBN Gateway map service has been terminated as of 1 April 2017.

As soon as a replacement map service is available, distribution maps will hopefully appear here again.

In the meantime, you can get some idea of distribution from the NBN Atlas website.

Silver Hook Deltote uncula

(Clerck, 1759)


Wingspan 20-22 mm.

Occupying marshes, fens and acid bogs, this species has a scattered distribution over much of Britain, but is largely absent from most of central England.

The adults are on the wing from May to July, and can be attracted to light to a certain extent.

The larvae feed in late summer on sedges, including wood-sedge (Carex sylvatica), and grasses.
