More than 30 species of moth are dependent on Ash in some way including two UK Biodiversity Action Plan (BAP) species, one provisional Red Data Book list species and two nationally scarce species.

Some eight species of moth are solely dependent on the tree as a foodplant including the provisional Red Data book listed Pammene suspectana.

Director of Conservation, Dr Nigel Bourn, said: “Ash dieback poses yet another threat to Britain’s dwindling butterfly and moth populations.

“It could repeat the devastating losses of Elm-feeding species that we saw as a result of Dutch Elm Disease during the 1970s.”
