Crustacea: Copepoda - Cerambycoidea.com

Helina pertusa (Meigen)* - Larvae under the loose bark of decaying trees and in rot-holes,
where they prey on other fly larvae; also reported from a bird nest in a dead willow
branch. Midlands & south England, uncommon; Cos. Clare and Antrim.
Helina pulchella (Ringdahl) - RDB3. Has been reared from the nest of a tawny owl.
Helina subvittata (Séguy)* = rothi Ringdahl - Has been reared from larvae found beneath
poplar bark.
Phaonia - The larvae of various species can occur under bark, though not exclusive to dead
wood habitats; there are also more specific deadwood species the larvae of which are
predators:
Phaonia canescens Stein - RDB3. Has been reared from under bark, in rotten wood and from
fungi; south Britain.
Phaonia cincta (Zetterstedt)* - Develops in sap runs of broad-leaved trees, especially elm and
horse chestnut, where larvae prey upon those of lonchaeid, clusiid and Mycetobia
pallipes flies; also from wet, rotten fungus-ridden wood within trunk base of large old
live beech, and from damp tree humus from rot-hole in large live sycamore; south
Britain & Ireland.
Phaonia exoleta (Meigen)* - RDB3. Develops in water holes in old trees: elm, ash, beech,
horse chestnut, sycamore; its larva swims actively and feeds on mosquito larvae.
England & Scotland.
Phaonia gobertii (Mik)* - Larva found under sodden bark, especially elm and poplar, where
it preys on lonchaeid and clusiid fly larvae; it also develops in woodland leaf-litter
and fungi; widespread in Britain but very localised to older woods.
Phaonia laeta (Fallén) = trigonalis (Meigen) - RDB3. Develops in sap-runs on birch, horse
chestnut and oak, including trees with goat moth Cossus; has been reared from pupa
in birch rot-hole; southern Britain, but also reared from spruce in Tayside.
Phaonia mystica (Meigen)* = vittifera (Zetterstedt) - Has been reared from a rotten log.
Phaonia pallida (Fabricius)* - Has been reared from terrestrial fungi and rotten wood in
woodland; common and widespread in Britain and Ireland.
Phaonia palpata (Stein)* - Has been reared from wood mould and rotten wood in damp
shady woodland; wide-ranging but localised over most of Britain and Ireland.
Phaonia pratensis (Robineau-Desvoidy) - Nationally Scarce. Has been reared from larvae in
sap exuding from birch; south Britain.
Phaonia rufiventris (Scopoli)* = populi Meigen - Has been reared from fungi and dead or
dying trees; widespread and fairly common throughout Britain and Ireland.
Phaonia serva (Meigen)* - Has been reared from larvae found beneath poplar bark; in
wooded or at least well-treed areas. Wide ranging and fairly common in Britain and
Ireland.
Phaonia subventa (Harris)* =variegata (Meigen) - Develops in mostly terrestrial fungi; also
rotten wood, including conifers. Widespread and common in woods.
Calliphoridae
Bellardia bayeri (Jacentkovský) - A parasitoid of earthworms living in rotten wood, reared in
Scotland and adults collected at two English sites: Mark Ash in New Forest, and
Buckingham Palace Gardens.
Rhinophoridae
Melanophora roralis (Linnaeus)* - Parasitic on woodlice in deadwood.
Paykullia maculata (Fallén)* - Parasitic on woodlice under loose bark on deadwood; adult
runs actively over surface of tree trunks.
Rhinophora lepida (Meigen)* - Parasitic on woodlice in deadwood.
