cultured in borings; mainly oak Quercus, but also beech Fagus and other broadleaved<br />
trees. Widespread in southern England and Wales, but absent from far southwest.<br />
Platypus parallelus (Fabricius) – RDBI. Presently expanding its Oriental range; W Kent:<br />
only three specimens known - 1832, 1973, 1983, presumed to be only casual imports.<br />
Hymenoptera<br />
SYMPHYTA - Sawflies<br />
Xiphydriidae - The larvae bore in wood of broad-leaved trees; development is within a<br />
year; pupation in chamber below sapwood; dependent on the presence of a symbiotic<br />
fungus in the tunnels.<br />
Xiphydria camelus (Linnaeus) - Oviposit through bark of recently dead branch of streamside<br />
alder Alnus or birch Betula, eggs deposited in cambial layer; larva tunnels in wood for<br />
10 months; circular flight holes; rare & local.<br />
Xiphydria longicollis (Geoffroy) – [pRDBK]. Has been reared from fallen field maple Acer<br />
campestre branch, Windsor Forest; also at Maidenhead & Wisley.<br />
Xiphydria prolongata (Geoffroy) - Larvae develop in woody stems of willows Salix; adults<br />
emerge from mid June to mid August; oviposition in bark of fresh willow logs; larvae<br />
initially bore in cambial layer, then in superficial sapwood. Rare & local, mostly SE<br />
England, as far N as Nottinghamshire.<br />
Siricidae - The larvae bore in standing or freshly cut timber; males spend lives in tree tops<br />
where mate; females lay eggs into borings; larvae tunnel in wood for 2-4 years, but if<br />
wood cut & dried take longer; pupate below sapwood; abdominal sacs with spores of<br />
Amylostereum areolatum, which are injected into tree during oviposition.<br />
Tremex columba (Linnaeus) – Casual/ Importation. Bores in Acer, oak Quercus, elm<br />
Ulmus, etc; N. American sp., only in imported wood.<br />
Xeris spectrum (Linnaeus) - Lacks fungal spore sacs & only oviposits in trees previously<br />
colonised by other siricids; has been reared from larch Larix in Hants, and an<br />
occasional import.<br />
Uroceras gigas (Linnaeus) - Holarctic species established in GB, possibly native in<br />
Caledonian forest areas; bore conifers.<br />
Sirex noctilio Fabricius – Naturalised. Holarctic species established in GB; bores conifers.<br />
Sirex cyaneus Fabricius – Naturalised. Holarctic species established in S. England &<br />
Scotland, American in origin; bores conifers.<br />
Sirex juvencus (Linnaeus) – Holarctic species established in GB; possibly native.<br />
Cephidae<br />
Janus femoratus (Curtis) - Larvae develop in oak Quercus twigs; SE of Wash/Severn line.<br />
PARASITICA - Parasitic Wasps. Approx 5500 species in total, and very diverse in<br />
biology; these are particularly under-studied and the following is almost certainly<br />
only a poor representation of the total fauna.<br />
ICHNEUMONOIDEA - Exclusively parasitic (parasitoids).<br />
Ichneumonidae<br />
Ichneumonidae: Pimplinae - The majority are ectoparasitoids of immature<br />
Lepidoptera, Coleoptera, Hymenoptera, Diptera or Arachnida, while some are<br />
pseudo-parasitoids of spider egg sacs, and one group are endoparasitoids in<br />
endopterygote pupae and prepupae. Several species are hyperparasitic, often<br />
facultatively, and a few are cleptoparasitic on other pimplines. (Fitton et al, 1988).<br />
