Criorhina berberina

Criorhina berberina (Fabricius, 1805)

Biology & ecology:

The larva has been found in rotten wood in cavities in the trunk of Birch Betula sp. and decaying roots of Beech Fagus sylvatica, but is probably associated with a wider range of deciduous species. Adults are usually found in woodland with over-mature trees and are often seen visiting flowers or settled on sun-lit foliage. Males patrol flowers and flowering shrubs. Females can be found flying around the base of stumps and dead or dying trees.

Distribution:

Widely distributed in England and Wales, extending north to the Central Lowlands of Scotland. Thereafter there are scattered old records further north and a recent record from the Moray Firth.

Status & conservation:

There has been a substantial decline in occurrence over the past 35 years, except in the uplands where numbers of records have increased. The latter may reflect increased effort to achieve coverage of less recorded areas.

Recorded from 516 hectads since 1990.
