Strangalia melanura (Linnaeus)* - Larvae in thin, decayed oak Quercus branches and in
broom Cytisus roots; also in other trees.
Strangalia nigra (Linnaeus) - Nationally Scarce A. Larval stages undescribed in GB, but
probably in broad-leaved trees; adults at flowers.
Strangalia quadrifasciata (Linnaeus)* - Four-banded Longhorn. Develops in dead and
decaying stumps, especially birch Betula, but also a wide range of other broad-leaved
trees, and once in spruce Picea; larvae make meandering galleries deep in the
sapwood; wood sizes down to 15cm diameter, wet or dry, but dry needed for
pupation; adults visit flowers, sun-loving and fly on hot sultry days. Widespread in
the British Isles, albeit very thinly so in many areas and most sparingly in Ireland.
Strangalia revestita (Linnaeus) - RDB1. Larval habitat not known in GB, but most probably
in living oak Quercus branches, and possibly other broad-leaved trees; does not come
to blossom; lives in tree canopy; S Midlands & SE England. Widespread on
Continent, although has become rarer and more localised even there; develops
preferably in trees on the edge of woodlands and open-grown situations such as parks;
feed in thinner branches, especially those with damaged bark; also in moist decaying
tree stumps.
Cerambyx cerdo Linnaeus – Fossil. Fossil evidence for occurrence in Britain up until 3690
+/-100 BP, from Cambridgeshire fenland bog oaks Quercus. More recent records
have all been casual importations. Widespread throughout Europe but increasingly
rare or absent in the north.
Cerambyx scopolii Fuessly - Extinct Native/Casual Import. 19 th Century records from the
London area, and most recently 1902. Possibly a native in south-east England which
has become extinct, but equally possibly an introduction with imported timber.
Hesperophanes fasciculatus (Fald.) - Sub-fossil. A largely Mediterranean species, known in
Britain from 2nd Century AD Roman site in Worcestershire, but presumed to have
been imported in timber.
Trinophyllum cribratum Bates – Naturalised. Import from India, but possibly established; in
well-seasoned oak Quercus and other hard- and softwoods.
Gracilia minuta (Fabricius) - Basket Longhorn. RDB2. Larvae in dry dead twigs and small
branches, incl. bramble Rubus canes and wickerwork; flight holes c.2mm and oval; 2
year cycle.
Obrium brunneum (Fabricius) – Naturalised. Larvae in dead twigs and branches of pine
Pinus, spruce Picea and larch Larix; accidental introduction south of the Thames.
Obrium cantharinum (Linnaeus) – Extinct. Larvae in dead wood beneath bark on crab apple
Malus, aspen and poplar Populus spp, possibly also oak Quercus and birch Betula;
annual life cycle and larvae feed under bark, entering sapwood only to pupate; mainly
northern outer London area in early 19 th century, also Bovey Tracey (1929), but not
seen for since.
Nathrius brevipennis (Mulsant)* - Naturalised. Established in Britain & Ireland; larva
particularly attacks thin growths, such as osier Salix beds, dog-rose Rosa canina
stems, wattle fences, wickerwork; 2 year cycle, pupating in April and May.
Molorchus minor (Linnaeus) – Naturalised. 2 year cycle, larvae attacking exposed roots and
dead or cut branches of various broad-leaves and conifers; pupae over-winter; adults
at blossom.
Molorchus umbellatarum (von Schreber) - Nationally Scarce A. Larva in trunks, slender or
broken off branches and dead twigs of bramble Rubus, crab apple Malus, dog-rose
Rosa canina, guelder rose Viburnum, pine Pinus, spruce Picea and fruit trees
(Rosaceae); 2 year cycle; pupae over-winter; adults at blossom.
