Tenebrionidae - Darkling Beetles
Bolitophagus reticulatus (Linnaeus) - RDB3. In old bracket fungi of Fomes fomentarius
where it fruits on dead birch Betula trunks; confined in Britain to the Scottish
Highlands, but much more widespread elsewhere in Europe.
Eledona agricola (Herbst) - Nationally Scarce B. Develops primarily in the fruiting bodies
of Laetiporus sulphureus and very occasionally adults have been reported from other
similar soft annual bracket fungi; mostly in old wood pastures. Central and southern
Britain; one record from Dumfriesshire.
Diaperus boleti (Linnaeus) - RDB2. Develops deep inside large brackets of Piptoporus
betulinus on birch Betula; also reported from Polyporus squamosus on black poplar
Populus nigra; adults and larvae feed on soft fleshy part of the fungus just above the
pore tubes and close to the stem; pupates within the fungus; one year development.
Has been found widely across England, although very localised.
Scaphidema metallicum (Fabricius) - Nationally Scarce B. Associated with decaying wood,
frequently on quite small sticks and branches, and usually in very moist and shady
conditions; mostly reported from elm Ulmus, but also oak Quercus, beech Fagus, and
hawthorn Crataegus; known from woods, parks, old scrub & hedgerows. Almost
certainly declining and status in need of revision.
Platydema violaceum (Fabricius) - RDB1. In the fungus Auricularia auricula-judae on elder
Sambucus and A. mesenterica on elm Ulmus; larvae and adults in outer rotted parts of
fungus, where also pupates.
Alphitophagus bifasciatus (Say) - Mould feeder, mainly associated with mouldy grain and
decaying vegetable matter generally including decaying tree stumps.
Pentaphyllus testaceus (Hellwig) – Extinct. Found once in Britain in “Polyporus squamosus”
placed as a trap in a “partially decayed oak”, Hornsey, N. London, 1876. Known on
Continent from decaying bracket fungus Laetiporus sulphureus on oak, also in broadleaved
leaf litter and red-rotten oak and other decaying timber.
Alphitobius diaperinus (Panzer)* - Lesser Mealworm Beetle. Mainly known from stored
products and especially deep litter poultry houses, but also very occasionally in the
wild associated with decaying timber.
Alphitobius laevigatus (Fabricius) - Black Fungus Beetle. Mainly known from stored
products, but occasionally in garden refuse or associated with decaying timber.
Corticeus bicolor (Olivier) - Commensal in burrows of bark beetle Scolytus scolytus & S.
multistriatus in elm Ulmus, mainly feeding on fungi and detritus, but will also feed on
eggs, larvae and pupae of not only the bark beetle but also other associated insects;
more rarely associated with Daldinia concentrica on old ash Fraxinus and with
Polyporus squamosus; also occur under bark on oak Quercus. Eastern Britain,
extending across to the Welsh Marches.
Corticeus fraxini (Kugelann) – Naturalised. Inhabits burrows of bark beetle Ips sexdentatus
in pine Pinus, also in burrows of Orthotomicus spp.; introduced in pine pit-props from
France, early C19th.
Corticeus linearis (Fabricius) - Inhabits burrows of bark beetle Pityogenes bidentatus under
bark of smaller upper branches of conifers. Probably an adventive? - discovered new
to GB in 1898 at Oxshott.
Corticeus unicolor Piller & Mitterpacher - RDB3. Develops chiefly in freshly dead birch
Betula wood, also beech Fagus and oak Quercus, and is probably predatory on larvae
of the beetle Hylecoetus and other wood borers. Confined to the north Midlands, with
two distinct areas: Nottinghamshire/S. Yorkshire and Cheshire, probably now extinct
in latter area.
