Anaspis thoracica (Linnaeus)* - Nationally Scarce A.
Cerambycidae - Longhorn Beetles. Many exotic longhorns turn up in timber yards and
buildings due to importation of timber. Some have become established. Obvious
casuals are not included. 10km square distribution maps are available (Twinn &
Harding, 1999).
Prionus coriarius (Linnaeus) -The Tanner. Nationally Scarce A. Develops in stumps and
the decaying roots of old oaks Quercus, also in a wide range of other tree species;
usually where tree growing in damp site; prefers old oak parkland or open wood
pasture; larval development 3-4 years; pupates in earthen cocoon among roots and
may take several years before reaching adult stage; beetles appear midsummer and are
crepuscular. Thinly scattered across southern Britain and apparently extinct in many
areas of former range.
Arhopalus rusticus (Linnaeus) - Dusky Longhorn. Larva in standing and fallen trunks and
stumps of various conifers, and will attack larvae of the long-horn beetle Asemum
striatum if encountered; up to 2 years life cycle, pupal eclosion from May onwards;
nocturnal, hiding under bark by day, but attracted to light after dark; also active in hot
weather; Scottish native but has spread widely with conifer plantations over England.
Arhopalus tristis (Fabricius) – Naturalised. Wood-borer in exposed roots and boles, also in
dying trees and fire-damaged timber; pine Pinus & spruce Picea; larvae up to 4 years,
pupating from June onwards; largely nocturnal, but sun on logs and stumps; active
and agile beetle; presumed introduction.
Asemum striatum (Linnaeus)* - Highland pine Pinus forest species which has spread with
softwood forestry; mainly develops in pine stumps and exposed roots of freshly cut
trees, but will use larch Larix and firs; 2-3 year life cycle, eclosion in April and May;
crepuscular.
Tetropium castaneum (Linnaeus) – Naturalised. Recent established in Scotland, from the
Continent; typically a montane species, although has been found in lowlands. Larvae
mainly in spruce Picea, but also other conifers; attacks standing live and dying trees;
adult emerges in April and a strong flier.
Tetropium gabrieli Weise – Naturalised. Larch Larix plantations, also in other conifers;
adult oviposits in freshly cut larch logs and branches; also attacks live trees; one year
cycle.
Rhagium - The larvae feed upon bark, phloem and cambium.
Rhagium bifasciatum Fabricius* - Develops in rotten boughs, stumps and trunks, prefers
decaying logs and stumps of pine Pinus, but found very widely, even in old posts.
Rhagium mordax (Degeer)* - Larvae develop in decaying timber, preferring the cambium
and outer sapwood of rotting boles or stumps; most often found in oak Quercus, but
also in a wide range of other trees; adult formed by August, but remains in pupal cell
until following Spring.
Rhagium inquisitor (Linnaeus) - Nationally Scarce B. Preference for conifers, but also birch
Betula & oak Quercus, stumps and logs; native only in Scotland, adventives and
accidental introductions elsewhere.
Stenocorus meridianus (Linnaeus) - Develops in stumps and dead roots of a wide range of
trees, and has been seen emerging from pine Pinus posts; two year larval duration;
woods and hedgerows.
Acmaeops collaris (Linnaeus) - RDB1. Larvae under bark on decaying exposed roots and
dead branches of oak Quercus; also in ash Fraxinus and aspen Populus tremula; lives
in empty galleries of other wood-borers, feeding on the underside of the loose bark;
larva very active, and crawls over ground in search of other deadwood; after 2 years
pupates in autumn in shallow underground cell close to host tree's roots; adults at
64
