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.

Pocota personata



Range & Status

Recorded at a few sites between Cornwall and Yorkshire, with most records from the New Forest and Windsor Forest. An elusive indicator of ancient woodland.

Regional Distribution

Recorded in VC1 at Ladock Woods (1990).

Habitat & Ecology

Occurs in broadleaved woodland particularly with Beech Fagus sylvatica which are old enough to have developed rot holes at a substantial height. Adults fly from April to June on tree trunks or at Hawthorn Crataegus monogyna blossom. The larvae develop in rot holes, possibly needing an unknown microclimate.

Threats

Loss of suitable trees.

Conservation

Retention and protection of any potentially suitable trees for larvae, with adjacent Hawthorn for nectaring adults. Listed (UK BAP long list) as a globally threatened/declining species (BSGR, 1995) but does not appear to be on the UK BAP Priority Species list (2007).
