Rhizophagus oblongicollis Blatch & Horner - RDB1. Probably develops underground at the
roots of old oaks Quercus, but at times comes to the surface and seeks new larval
habitat. Above ground it is attracted to sap associated with damaged bark.
Rhizophagus parallelocollis Gyllenhal* - Under bark on deadwood.
Rhizophagus parvulus (Paykull) - RDB3. Under bark of dead broad-leaved trees; Scottish
Highlands.
Rhizophagus perforatus Erichson* - Under bark on dead broad-leaved trees.
Rhizophagus picipes (Olivier) - Nationally Scarce A. Under sappy bark of various dead
trees.
Cyanostolus aeneus (Richter) - Nationally Scarce A. Under bark on dead wood and in
crevices in bark, usually on or near water; probably a predator of bark beetles; N & W
Britain & Weald.
Silvanidae - Larvae predators on other insect larvae beneath bark on deadwood.
Silvanus bidentatus (Fabricius) - Nationally Scarce B. Under sappy bark of deadwood of
various trees, incl. pine Pinus; usually with S. unidentatus. Central and eastern
England, as far north as Co Durham; absent Wales and south-west; a single Scottish
record in west.
Silvanus unidentatus (Olivier) - Under sappy bark of deadwood of oak Quercus and beech
Fagus, but also a wide range of other broad-leaved trees. Central and eastern
England; widespread; single locality in Kirkcudbrightshire.
Silvanoprus fagi (Guérin-Méneville) - RDB1. Under bark of beech Fagus and pine Pinus
deadwood.
Uleiota planata (Linnaeus) - Nationally Scarce A. Larvae probably fungus-feeders under
sappy bark, typically beech Fagus and sweet chestnut Castanea, but also from other
broad-leaved trees; adults over-winter. Mainly in southern and eastern England, but
with single reports from W. Glamorgan and Aberdeenshire.
Dendrophagus crenatus (Paykull) - Nationally Scarce B. Larvae are fungus-feeders under
dead bark of broad-leaved trees and conifers; relict woodlands of primary pine Pinus
forest; Scotland. Limited to the mountainous and colder areas elsewhere in Europe,
especially ancient spruce Picea forest.
Cucujidae - Flat Bark Beetles. Larvae predators on other insect larvae beneath bark on
deadwood.
Pediacus depressus (Herbst) - Nationally Scarce A. Attracted to freshly cut or broken
stumps; also from goat moth Cossus burrows. Very thin scatter of sites across
England; one Welsh locality, in Carmarthenshire.
Pediacus dermestoides (Fabricius) - Develops beneath bark on dead broad-leaved timber in
the early stages of decay, especially in shattered ends of broken boughs; larvae feed
on other insect larvae, while adults are fungivorous. Widespread in ancient
woodlands and wood pastures throughout southern Britain, as far north as N.
Yorkshire.
Laemophloeidae
Laemophloeus monilis (Fabricius) - RDB1. Under bark of cut ends of beech Fagus.
Cryptolestes confusus – [RDB1]. In beech Fagus log, Windsor 1987.
Cryptolestes duplicatus (Waltl) - Under bark on dead timber, reputedly widespread in S.
England.
Cryptolestes ferrugineus (Stephens)* - Under bark on beech Fagus, especially where still
sappy; also on oak Quercus, horse chestnut Aesculus, etc. Possibly associated with
ancient wood pastures, but also in granaries. Scattered across southern England.
Cryptolestes spartii (Curtis) - Nationally Scarce A. Mainly in dead broom Cytisus stems, but
also under bark of deadwood of various broad-leaved trees.
