Ephialtes manifestator (Linnaeus)* - Hosts are rather deeply concealed in long dead and
sometimes rotten wood, and it has on several occasions been observed probing old
emergence holes of wood-boring beetles in dead trees and fence posts. This suggests
that aculeate Hymenoptera may be among the regular hosts, as is borne out by the
rearing of a single male from the digger wasp Trypoxylon sp. A specimen is also
claimed to have been reared from the longhorn beetle Callidium violaceum.
Uncommon; southern England and Wales; Co Kerry. (Fitton et al, 1988).
Dolichomitus agnoscendus (Roman)* - Has been reared from the weevil Mesites tardii, from
dead Rosa stems, and alder Alnus logs. Rare, but widely distributed. (Fitton et al,
1988).
Dolichomitus diversicostae (Perkins) - Has been reared from the longhorn beetle
Acanthocinus aedilis in pine Pinus; rare, northern Scotland (Fitton et al, 1988).
Dolichomitus imperator (Kriechbaumer) - Circumstantial evidence that the hosts are in long
dead timber, such as the longhorn beetle Rhagium, but one also found in the borings
of Arhopalus rusticus in recently dead pine Pinus. In Scotland often in relict
Caledonian pine forest, but also in the ancient birch Betula woods of the extreme
north and west. Also reported from Hampshire. (Fitton et al, 1988).
Dolichomitus mesocentrus (Gravenhorst) - Appears to be associated principally with beetle
hosts in dead oak Quercus and beech Fagus. Uncommon, but widely distributed in
southern Britain. (Fitton et al, 1988).
Dolichomitus messor (Gravenhorst) - One specimen supposedly reared from the clearwing
moth Synanthedon vespiformis in Herefordshire (Fitton et al, 1988). Reported to be
parasitic on the longhorn beetles Lamia textor, Mesosa nebulosa.
Dolichomitus populneus (Ratzeburg) - Has mostly been reared from the longhorn beetle
Saperda populnea, but also from the clearwing moth Synanthedon flaviventris and the
micro Lampronia fuscatella. These hosts all cause galls in small branches and twigs,
respectively of Populus, Salix and Betula. Uncommon; widely in southern England.
(Fitton et al, 1988).
Dolichomitus pterelas (Say)* - Reared once from the longhorn beetle Stenostola ferrea.
Southern England, rare; Co Kerry. (Fitton et al, 1988).
Dolichomitus terebrans (Ratzeburg) - Has often been reared as a parasitoid of the large
weevils in pine Pinus bark Pissodes castaneus and P.pini; and has become a regular
parasitoid of the recently established bark beetle Dendroctonus micans in spruce
Picea. Uncommon, but widely distributed among conifers throughout Britain. (Fitton
et al, 1988).
Dolichomitus tuberculatus (Geoffroy)* - Reared from the bark weevil Hylobius abietis, the
longhorns Acanthocinus aedilis and ?Rhagium mordax, and more doubtfully from the
clearwing moth Synanthedon culiciformis; from conifers and Betula. Uncommon but
widely distributed in GB and Ireland. (Fitton et al, 1988).
Townesia tenuiventris (Holmgren) - In Finland reared from the bee Chelostoma florisomne
and less often from the digger wasp Trypoxylon figulus nesting in dead wood. Rare,
but widely distributed in southern England. (Fitton et al, 1988).
Paraperithous gnathaulax (Thomson) - It is suggested that it probes for hosts pupating
beneath partly loose bark. Rare, but widely distributed, in Scotland and to a lesser
extent southern England. (Fitton et al, 1988).
Liotryphon spp - Use their ovipositors to probe bark crevices, etc, or to penetrate the weak,
prepared exit sites of insects with non-mandibulate adults (eg moths) pupating in bark
and wood, rather than to drill through bark. They are not therefore part of the
saproxylic fauna. (Fitton et al, 1988).
