Julidae
Cylindroiulus punctatus (Leach)* - Inhabits dead and decaying timber, but moves into soil
and leaf-litter in winter. Common and widespread throughout Britain and Ireland.
Cylindroiulus britannicus (Verhoeff)* - Most often found under bark of dead broadleaves and
in wood-decay beneath. Widespread but very local.
Cylindroiulus parisiorum (Brolemann & Verhoeff) - Nationally Scarce. Under bark of old
stumps. Very thin scatter of sites across England from Dorset to Scottish border.
Blaniulidae
Proteroiulus fuscus (Am Stein)* Typically living under bark of deadwood of conifers and
broadleaves; occasionally in leaf litter and soil. Common & widespread.
Nemasomatidae
Nemasoma varicorne C.L. Koch* - Almost exclusively under bark of deadwood of conifers
and broadleaves; most frequently associated with beech, ash and poplar. Throughout
GB, but local. Apparently very rare in Ireland.
Chilopoda - Centipedes
Centipedes are dorso-ventrally flattened animals and thereby ideally suited to life between
bark and sapwood on decaying wood. A wide variety of species may be found within
decaying wood but only the following may be considered characteristic of this situation
although none are confined to it. All are primarily general predators of other invertebrates.
Geophilidae
Brachygeophilus truncorum (Bergso & Meinert)* - Particularly common beneath bark and in
decaying timber generally, but occasionally found in other situations.
Lithobiidae
Lithobius variegatus Leach* - Widespread and common in semi-natural habitats in oceanic
Britain and Ireland, but increasingly confined to woodland in the east of its range. In
woods, regularly found beneath bark on decaying timber.
Pseudoscorpiones - False Scorpions
False scorpions are all carnivorous and live in a wide variety of habitats. Only a few are
associated with dead and decaying timber.
Lamprochernes chyzeri (Tomosvary) - Under bark of deadwood of old broadleaves; phoretic
on flies. Scattered across lowland England, mainly in old wood pastures.
Allochernes wideri (C.L. Koch) - Under bark and in rotten wood of dead trees, especially
oak; also in hay & grain in barns. Mostly C & E. England; old records for N.
Lancashire & Manchester.
Chernes cimicoides (Fabricius)* - Typical of old native woodland and wood pasture; under
bark and in rotting wood of dead and decaying trees, especially oak and beech.
Widespread in Lowland Britain north to Yorkshire. Reported from Ireland.
Dendrochernes cyrneus (L. Koch) - RDB3. Ancient woodland and wood pasture, under
pieces of loose bark and in very dry sapwood of dead parts of overmature trees,
especially oak; also in rot holes. Prefers timber heated by the sun, and reported to be
active on outside surfaces of trunk on calm warm summer evenings. Rare species,
most sites within area enclosed by London to Sherwood to Gloucestershire. Phoretic
on longhorn beetles.
Withius piger (Simon) - Under dead oak bark at Dunham Park, Cheshire; otherwise only
known from warehouses.
