Crustacea: Copepoda - Cerambycoidea.com

in lowland England, but absent from south-west and north; Welsh record from
Denbighshire. Widespread on continent.
Thanasimus formicarius (L.)* - Pink larvae and adults feed on bark beetles, and also other
beetles, in hard dead timber; especially ash Fraxinus and elm Ulmus, but also pine
Pinus and oak Quercus. Widespread in central and eastern England, more sparingly
in north and west. Rare in Ireland and only reported from Counties Dublin and
Wicklow.
Thanasimus femoralis (Zetterstedt) = rufipes (Brahm) - RDB3. Associated with Scots pine
Pinus sylvestris in Highlands; feed on bark beetles. North and central Europe.
Paratillus carus (Newman) - Naturalised. Larvae feed on the larvae of Lyctus beetles;
usually in timber yards, but occasionally in native situations. An Australian import,
first recorded in Britain in 1933.
Tarsostenus univittatus (Rossi) – Extinct. A predator of immature stages of Lyctus beetles.
Cosmopolitan.
Korynetes caeruleus (Degeer) - Nationally Scarce B. Larvae in galleries of Anobium and
Xestobium beetles in old hard timber, both in old trees and in buildings, and predatory
on their larvae; also reported from old bones where feed on dermestid larvae.
Melyridae - Soft-winged Flower Beetles. Larvae predatory, some associated with dead
timber, although in some cases perhaps only as a pupation site.
Aplocnemus impressus (Marsham) = pini Redtenbacher - Nationally Scarce B. Larvae feed
on scolytid beetle larvae, in branches, eg of pear Pyrus, oak Quercus, sycamore Acer
& pine Pinus.
Aplocnemus nigricornis (F.) - Nationally Scarce A. As above. Possibly some association
with hollow oaks Quercus. Mainly known from ancient wood pastures.
Dasytes aeratus Stephens* - Favours open woodland situations, especially on neutral to baserich
soils: adults usually found at blossom, especially on hawthorns Crataegus; the
larvae are carnivorous over and under bark on live trunks as well as deadwood,
feeding on dead invertebrates - has been reared in numbers from oak Quercus timber.
Locally common in southern England, becoming very much more local in the north.
Dasytes niger (L.) - Nationally Scarce A. Adults frequent open grasslands, visiting flowers,
but have also been found in numbers active over a standing dead tree trunk in warm
sunshine. Larvae are believed to develop in decaying wood.
Dasytes plumbeus (Müller, O.F.) - Nationally Scarce B. Adults most often found in
grasslands, but perhaps always near to trees. Larvae are said to develop in decaying
wood.
Dasytes puncticollis Reitter - Nationally Scarce B. Associated with a variety of grassland
situations.
Ebaeus pedicularius (L.) – Extinct. Windsor Forest, 19th C.
Hypebaeus flavipes (F.) - RDB1 & BAP Grouped Species Statement. Larvae in galleries
made by woodborers in ancient oaks Quercus in open sunny situations; Moccas Park.
Axinotarsus marginalis (Laporte) - Recent Colonist. Reared from larvae in fallen oak
Quercus branch; recent arrival apparently from near Continent, probably a natural
range extension, now well established over much of S England.
Axinotarsus ruficollis (Olivier) - Probably develops in dead twigs.
Sphinginus lobatus (Olivier) – RDBK. Probably develops in dead twigs of oak Quercus or
other trees; discovered in Hampshire in 1982.
Malachius aeneus (L.) - RDB3. Larvae under bark on logs. Adults active in grassy clearings
and rides within woodland.
