Fen Raft Spider makes UK comeback from brink of extinction

Summarised from 2 outlets · Updated 27 Oct, 12:02 · Archive

The Fen Raft Spider, nearly extinct in the UK a decade ago, is recovering thanks to RSPB conservation efforts.

The Fen Raft Spider, one of the UK's rarest invertebrates, is recovering from near-extinction thanks to RSPB conservation efforts. The species had dwindled to critical levels by 2010 but has now expanded to 3,750 breeding females across 12 sites in Norfolk alone.

The semi-aquatic spiders can run across water's surface to hunt. Their diet includes other spiders, damselflies, dragonfly larvae, fish and tadpoles. The females are notably large. They are easiest to spot in grazing marsh ditches from June to September, and are not venomous.

Tim Strudwick, the RSPB Mid Yare nature reserves site manager, said the spiders play an important role in maintaining aquatic diversity in grazing ditches on RSPB reserves. He described the females as 'impressive in size, but also beautiful – they are truly special to see'. The spiders can also be seen at Strumpshaw Fen in Norfolk, though they are 'fairly shy'.
