Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Acanthiophilus helianthi - Poplar Leaf Roller

Range & Status

Throughout southern Britain but very localised.

Regional Distribution

Eight sites known, along the north coast, including Porth Joke and Glebe Cliff, Tintagel.

Habitat & Ecology

Associated with unimproved grasslands where management encourages good flowering and seed-set of Black Knapweed Centaurea nigra and other herbs, the larvae developing in the seed heads.


Heavy grazing, which leaves sward short, but also undergrazing which allows coarsening and scrub development.


The Glebe Cliff site is owned by The National Trust.
