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.

Leptura aurulenta - Hornet Longhorn



Range & Status

A local, predominantly southern and western species in the British Isles.

Regional Distribution

Cornwall is perhaps the main UK concentration of the species; a large population in

Boconnoc Deer Park. May occasionally be overlooked as four-banded longhorn L.

quadrifasciata , which is the rarer of the two in Cornwall.

Habitat & Ecology

Larvae develop in the cambial layer of large freshly dead trunks and boughs of broadleaved trees in open woodland and pasture-woodland. Adults nectar at flowers of umbellifers, Bramble Rubus fruticosus agg. and Broom Cytisus scoparius .

Threats

Clearance of dead and fallen trees and branches; gaps in age classes of broadleaved trees; loss of old trees.

Conservation

Boconnoc Park has a sympathetic owner and is a SSSI.
