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.

Amphimallon ochraceus - A chafer

Range & Status

Scattered along Welsh coast and the south-west peninsula of England to East Sussex. Not uncommon in Dyfed and Lleyn.

Regional Distribution

Reported from a number of localities in the past but not since 1917 when it was seen

widely on the north coast in the vicinity of St. Merryn and St. Eval (Lamb, 1917). It seems inconceivable that such a large beetle which flies in warm sunshine around midday should have escaped attention since then; it must surely be extinct in Cornwall.

Habitat & Ecology

Associated with unimproved coastal grasslands and heathlands, where the larvae are presumably generalist root-feeders in the turf.


None known.
