S. & E. England, north to Yorkshire; rarer in west; Gwent, Powys. Association with
ancient sites strongest in west.
Paromalus parallelepipedus (Herbst) - RDB1. Under bark on dead timber; New Forest &
Kent. Relict old forest species.
Epierus comptus Erichson – RDBK. Discovered under bark of a mature fallen beech Fagus,
1980, Groveley Wood, S. Wilts, and also under beech bark in the New Forest in 2000.
Ptiliidae Feather-winged Beetles - Mould-feeders, living between the bark and sapwood of
dead trees, where conditions are slightly moist and mouldy.
Nossidium pilosellum (Marsham)* - Nationally Scarce. Develops in decaying wood,
particularly rotten stumps and damp, rotten, fungus-colonised timber, and especially
elm Ulmus and beech Fagus; in Polyporus squamosus on ash Fraxinus (Glos); in
hollow apple tree Malus (Worcs); in a gill fungus on oak Quercus; in wood frass in
Dorcus burrows.
Ptenidium formicetorum Kraatz* - Rotten wood is probably the main habitat of this species,
even though it does occur from time to time in nests of wood ants Formica spp and in
decaying vegetable material.
Ptenidium gressneri Erichson* - Nationally Scarce. Only found in ancient deciduous forests,
generally in moist crumbly wood mould in hollow trunks & rot holes; also in nests of
hornet Vespa crabro and squirrel dreys in hollow trees; most records from beech
Fagus.
Ptenidium turgidum Thomson, C.G. – RDBK. In moist crumbly decayed cavities inside
trunks of old broad-leaved trees, particularly beech Fagus and elm Ulmus, often in
company with ants.
Oligella intermedia Besuchet – RDBK. In humus at foot of old trees on Continent; Yorkshire
& 19C.
Micridium halidaii (Matthews, A.) – RDBK. Has been found in red-rotten wood from inside
hollow live oak Quercus (Windsor), also under bark of dead oak (Sherwood);
probably associated with mycelia of Laetiporus sulphureus. Also Richmond Park &
Calke Park. All sites are typical ancient wood pastures.
Ptiliolum caledonicum (Sharp) – RDBK. Mostly under bark of dead pine Pinus, but also
recorded on dead standing alder Alnus; Highlands.
Plitium subvariolosum (Britten) - With brown tree ant Lasius brunneus.
Ptinella aptera (Guérin-Méneville)* - Under bark of decaying oak Quercus and beech Fagus
timber.
Ptinella cavelli (Broun)* - Naturalised. Under tight bark of dead broad-leaves and conifers;
widespread; immigrant New Zealand species, widespread in Britain and Ireland.
Ptinella denticollis (Fairmaire)* - Nationally Scarce. Under tight bark of dead broad-leaved
timber; very local & rare.
Ptinella errabunda Johnson* - Naturalised. Under tight bark of most species of dead trees;
widespread & common in Britain and Ireland; immigrant, probably from New
Zealand.
Ptinella limbata (Heer)* - RDBK. Under bark of various dead broad-leaved trees and
conifers; old forest areas.
Ptinella taylorae Johnson* - Naturalised. Under tight bark of dead trees; immigrant New
Zealand species; not uncommon in W. England & Ireland.
Pteryx suturalis (Heer)* - Under bark and in rotten wood of dead broad-leaved trees, rarely in
conifer; local & scarce.
Leiodidae - Some species feed on carrion, others on subterranean fungi or on slime fungi
(Myxomycetes) on dead wood. All species of Anisotoma have an obligate association
