Acalles ptinoides (Marsham)* - Nationally Scarce B. - Confined to primary woodland and
old heathland.
Acalles roboris Curtis* - Nationally Scarce B.
Scolytidae - Bark Beetles. Species feeding on wood (xylem) and/or phloem are usually
restricted to one or a few hosts, whereas those which carry their own symbiotic fungi
which break down the xylem (ambrosia beetles) may colonize a larger range of hosts.
Many species have been imported in timber and some have become established. A
number are more strictly phytophagous, their larvae feeding in the still living inner
bark of stressed or moribund stems or branches, but these have been included in the
list nonetheless.
Hylesinus crenatus (Fabricius)* - Large Ash Bark Beetle. Chiefly dying ash Fraxinus, also
oak Quercus, walnut Juglans, etc; in rather thick bark of trunk.
Hylesinus oleiperda (Fabricius) - Lesser Ash Bark Beetle. In recently dead branches & twigs
of ash Fraxinus; southern.
Hylesinus orni (Fuchs) - Nationally Scarce B. In recently dead slender branches of ash
Fraxinus; possibly not a distinct species.
Hylesinus varius Fabricius) - Common Ash Bark Beetle. In ash Fraxinus; in standing and
fallen recently dead trunks and boughs; makes short blind hibernation galleries in
crotches of live ash trees, where it is associated with bacterial disease ash rose canker;
usually two broods annually, probably only one in north.

Pinus, S England.

Tomicus minor (Hartig) - Lesser Pine Shoot Beetle. RDB3. Mainly in dead Scots pine Pinus
sylvestris, also in Norway spruce Picea; only native in Scottish Highlands, but
established in Dorset; tunnels under bark transverse.
Tomicus piniperda (Linnaeus)* - Pine Shoot Beetle. Dead conifers, especially pine Pinus;
tunnels under bark longitudinal; two broods annually. Widespread.
Polygraphus poligraphus (Linnaeus) - Naturalised. Dead pine Pinus and spruce Picea,
E.England.
Scolytus intricatus (Ratzeburg) - Develops under bark of sickly or freshly dead oak Quercus
boughs and branches; also in sweet chestnut Castanea and other broadleaves.
Widespread in England and Wales, reaching north to Lothians.
Scolytus laevis Chapuis - In dead and dying wych elm Ulmus glabra; probably introduced.
