of marshy areas and ensure that woodland streams remain
shaded and undisturbed.

MYCETOPHILA LAPPONICA
A fungus gnat LOWER RISK (Nationally Scarce)
Order DIPTERA
Family MYCETOPHILIDAE
Mycetophila lapponica Lundström, 1906
Identification The male genitalia were figured by
Lundström (1906).
Distribution Only so far known from four localities in
Scotland: Camghouran Birch wood (31 August 1987) and
Carie, Rannoch Forest (23 October 1990), Perthshire (P.J.
Chandler); Tokavaig Wood, Skye, North Ebudes (7 July
1991, A.E. Stubbs); Beinn Eighe NNR, West Ross (10 June
1984, I.F.G. McLean).
Habitat The sites include both broad-leaved woods and
Pine (Pinus) forest.
Ecology Biology unknown. The larvae probably develop in
lignicolous fungi. Adults recorded in June to August and
October.
Status Only recently recognised to occur in Britain and the
spread of records suggests that it is likely to be found more
widely within this range in the Scottish Highlands. Not
listed in Shirt (1987) and status revised from RDB 2 (Falk
1991).
Threats Clearance of woodland for intensive forestry or
agriculture. Removal of any old or diseased trees and dead
wood which may support fungus hosts.
Management and conservation Maintain native
woodlands in a natural state, retaining any old or diseased
trees and dead wood, especially in damp shaded situations,
ensuring the continuity of these habitats in the future. Avoid
drainage of marshy areas or disturbance of woodland
streams.
Published sources Chandler (1988).
MYCETOPHILA LASTOVKAI
A fungus gnat LOWER RISK (Nationally Scarce)
Order DIPTERA
Family MYCETOPHILIDAE
Mycetophila lastovkai Caspers, 1984
Identification Described and figured by Caspers (1984b).
Distribution Only known from the south-west of England
and South Wales: Maudlin Valley Woods, Cornwall (1983);
Fingle Bridge (1992) and Horner Water (1993), Devon;
Savernake Forest, Wiltshire (2004); Ridley Wood (1948),
Eyeworth Wood (1987), Mark Ash Wood (1989, 1991),
Vinney Ridge (1990), Brockenhurst Wood (1990, 1991) and
Denny Wood (2002), New Forest and Burhunt Gulley
(1989), Hampshire; Moccas Park NNR, Herefordshire
(1997); Llanover Park, Monmouthshire (1996); Pencelli
Mire, Breconshire (1997); Dinefwr Deer Park,
Carmarthenshire (1996).
Habitat Broad-leaved woodland.
Ecology Biology unknown. The larvae probably develop in
lignicolous fungi. Adults recorded from May to October.
Status Overlooked in Britain until after it was described
from Germany (fourteen of the fifteen records are post
1980), but evidently well established in the New Forest and
possibly in suitable sites elsewhere in the south-west. Not
listed in Shirt (1987) and status revised from RDB 2 (Falk
1991).
Threats Woodland clearance for agriculture or intensive
forestry. Removal of any dead wood and old or diseased
trees which may support fungus hosts.
Management and conservation Maintain woodlands in a
natural state, retaining old or diseased trees and dead wood,
especially in damp shaded situations, ensuring the
continuity of these habitats in the future. Avoid disturbance
of woodland streams which should remain shaded.

MYCETOPHILA LUBOMIRSKII
A fungus gnat LOWER RISK (Nationally Scarce)
Order DIPTERA
Family MYCETOPHILIDAE
Mycetophila lubomirskii Dziedzicki, 1884
Identification The male genitalia were figured by Chandler
(1977a).
Distribution Now known from eight sites in the southern
half of England: Covert Wood, Kent (7 May 1998, L.
Clemons); Wisley Common (23 April 1992 and 5 May
2001) and Boundless Copse (26 July 2002), Surrey (P.J.
Chandler); Lashford Lane Fen (July to August 1987,
Malaise trap, K. Porter), California Country Park (Alder
wood, 15 September and 13 October 1996, P.J. Chandler)
and Windsor Forest (15 August 1999, P.J. Chandler),
Berkshire; Felbrigg Great Wood (24 October 1975, J.W.
Ismay), Norfolk; Clowes Wood, Warwickshire (25
September 1985, M. Pugh).
Habitat Broad-leaved woodland.
Ecology Biology unknown. The larvae probably develop in
lignicolous fungi. Adults recorded in April and July to
October.
Status A poorly known species, with only the ten scattered
records despite relatively intense recent recording, but on
several occasions found singly suggesting that it may be
readily overlooked. Status revised from RDB 1 (Shirt 1987
and Falk 1991).
Threats Clearance of woodland for agriculture or intensive
forestry. Removal of any dead wood and old or diseased
trees which may support suitable fungi.
Management and conservation Maintain native
woodlands in a natural state, retaining any old or diseased
trees and dead wood, especially in damp shaded situations
suitable for fungal growth, ensuring the continuity of these
habitats in the future.
