Grynobius planus* - Develops in dead timber of various broad-leaved trees. Widespread,
although locally scarce; more frequent in Ireland than Britain.
Dryophilus pusillus (Gyllenhal)* - Naturalised. In wood and debris of pine Pinus and larch
Larix.
Ochina ptinoides (Marsham)* - Develops in dead thick stems of ivy Hedera on trees.
Xestobium rufovillosum (Degeer)* - Deathwatch Beetle. Bores in hard dead heartwood of
several hardwood species where damp and fungal decay is present - in building
timbers one fungus in particular Donkioporia expansa may be especially important;
larval period anything between 1 and 13 years, usually 3-7; pupates beneath outer
surface of timber in late summer (earliest 18 July), 3-4 weeks later adult, but remains
in pupal chamber until next Spring, when become sexually mature; males emerge
first; adult life short, at most 9-10 weeks after pairing; exit holes 2.1-3.1mm diameter;
wings well-developed, but flight very rarely recorded, and unlikely to colonise
buildings naturally. Flight occurs only when temperatures exceed 17�C and attracted
to light. Reputedly common in lowland England, but very rare in native situations in
the north (mainly introduced with timber in these areas?); throughout Europe;
introduced elsewhere. Develops in a range of trees on the Continent, but mainly oak
Quercus and willow Salix in southern Britain and confined to oak in the north
Midlands.
Ernobius abietis (F.) - Vagrant? New Forest, 1899.
Ernobius angusticollis (Ratzeburg) - Vagrant? Surrey.
Ernobius gigas (Mulsant & Rey) – Naturalised. Associated with burnt and dead pines Pinus
in S England.
Ernobius mollis (L.)* - Develops in dead branches of softwoods, larvae consuming the bark
but scoring sapwood, i.e. cambium feeder. Indigenous to north temperate regions,
being common in northern Europe, especially in Scandinavia; widespread in Britain &
Ireland; introduction in many parts of World.
Ernobius nigrinus (Sturm) - Develops in thin branches of pine Pinus and spruce Picea after
primary attack of Magdalis weevils and Hylastes bark beetles. Formerly confined to
Scottish Highlands, but now also in southern pine plantations.
Ernobius pini (Sturm) – Naturalised. Pine Pinus associate in S England.
Gastrallus immarginatus (Müller, P.W.J.) - RDB1 & BAP Priority Species. Develops in the
bark of old field maple Acer campestre and fruit trees, clusters of tiny exit-holes
occurring on well-lit live trunks; very localised in Windsor Forest but widely over
north Cotswolds and adjoining country. Sub-fossil records from Somerset Levels.
Hemicoelus fulvicornis (Sturm) - Develops in small dead branches of broad-leaved trees in
hedges, parks and woods; largely southern and eastern in Britain.
Hemicoelus nitidus (Herbst) – RDBI. On grey poplar in Suffolk, and reared from dead fallen
branch of field maple Acer campestre in Windsor Great Park. Possibly a relict old
forest associate.
Anobium inexpectatum Lohse - Nationally Scarce B. Develops in thick woody old ivy
Hedera stems; S. Britain, north to Yorks.
Anobium punctatum (Degeer)* - Furniture Beetle. Eggs laid in crack or groove in exposed
dead sapwood of living and dead trees, larvae bore within sapwood and heartwood,
and pupate just beneath outer surface; pupal stage a few weeks, but adult remains in
pupal chamber initially. Throughout British Isles, but most frequent in mild wet
climate of west, and in seaboard counties generally; indigenous in Temperate Europe
and probably Asia, introduced elsewhere.
