rotten wood; oak Quercus and beech Fagus.
Euplectus infirmus Raffray* - In rotten wood and under bark, especially willow Salix.
Euplectus kirbyi Denny - Nationally Scarce. Found beneath bark on dead broad-leaved
timber; also in tree hollows.
Euplectus nanus (Reichenbach) – RDBI. Under bark and in moist crumbly rotten broadleaved
timber.
Euplectus piceus Motschulsky* - Under bark of oak Quercus and beech Fagus, and in redrotten
oak.
Euplectus punctatus Mulsant* - RDB3. In moist crumbly rotten wood, oak Quercus and
beech Fagus, also pine Pinus in Highlands; primarily a relict species of primary
forest.
Plectophloeus nitidus (Fairmaire) - RDB2. In red-rotten heartwood and wood mould in old
hollow oaks Quercus; old forests and parks.
Trichonyx sulcicollis (Reichenbach) - RDB2. In rotten broad-leaved wood, especially old elm
Ulmus stumps. Possibly associated with Lasius ants.
Batrisus formicarius Aubé – Fossil. In Britain up until at least the Late Neolithic/Early
Bronze Age, from which fossil material has been found in Somerset Levels.
Batrisodes adnexus (Hampe) - RDB1. Adults in decaying timber of old broad-leaved trees,
with brown tree ant Lasius brunneus; probably a mite predator; has been reared from
a bracket fungus. Windsor & Epping Forests.
Batrisodes delaporti (Aubé) - RDB1. Adult in nests of brown tree ant L. brunneus, in
decaying wood of old broad-leaved trees; probably a mite predator. Windsor Forest.
Batrisodes venustus (Reichenbach) - Nationally Scarce A. Adults in decaying heartwood of
old broad-leaved trees; occasionally found in nests of brown tree ant L. brunneus and
jet ant L. fuliginosus. Widespread in Lowland England, although most often found in
the south.
Scirtidae
Prionocyphon serricornis (Müller, P.W.J.)* - Nationally Scarce B. Develops in waterlogged
hollows in old trees, especially beech Fagus, and including hollows amongst
roots; larvae aquatic, feed on detritus from dead leaves; adults active fliers, shortlived.
Widely across lowland England, but scarcer in the west and north; one record
from central Scotland.
Eucinetidae - Plate-thigh Beetles.
Eucinetus meridionalis (Laporte de Castelnau) - Larvae feed on fungi under bark of dead
trees, especially pine Pinus; adults at flowers, wintering amongst litter. Discovered
relatively recently; most likely a casual importation.
Clambidae
Clambus nigriclavis Stephens - Develop on damp twigs partly standing in water, larvae
feeding on hyphae and spores of moulds; northern & western sp.
Clambus pallidulus Reitter* - RDBK. In hollow apple Malus tree (Worcestershire); in debris
in rotten elm Ulmus stump, in moss among rotten logs.
Clambus punctulum (Beck)* - Slime mould feeder.
Lucanidae Stag Beetles - Develop in rotten deciduous wood.
Lucanus cervus (L.) - The Stag Beetle. Nationally Scarce B & BAP Priority Species.
Larvae in moist decaying wood near or below the soil surface, including decaying old
stumps, but also in base of fence posts; generally in light soils; larval development c.4
