Rare Weevil Discovered in Abney Veteran poplar

This little beauty is called Cossonus linearis and it only lives in rotting willows and poplars.  This means it needs old trees that have a lot of dead wood that is at just the right stage of decay.  The maggot like larva live in and eat the rotting wood.  The Abney Veteran Tree Project has been working to preserve Abney's most wildlife valuable trees by re-pollarding them.  This removes excess weight that might otherwise cause the trees to split apart or collapse.  Abney has nationally important populations of fungi and invertebrates.

This species of weevil is recorded from less than 30 tetrads (10km squares) in the whole of the UK making it nationally scarce A.  It is only recorded from two sites in London.
