Part 2: Nematocera and Aschiza not dealt with by Falk (1991) - JNCC

(1982), Dulsie (1989), Glen Affric, Kincraig and
Inchnacardoch Forest (1997) and Rothiemurchus (2004),
Easterness; Rogie Falls (1984), Alness (1984) and Loch
Achilty (2002), East Ross; Migdale Wood (1984) and
Torboll Wood (2002), East Sutherland.
Habitat Mainly recorded from broad-leaved or mixed
woodland.
Ecology Biology unknown. The larvae probably develop in
lignicolous fungi. Adults recorded from May to September.
Status Only recently recognised as British (Chandler 1988)
but evidently widespread in the Scottish Highlands. All of
the 25 known sites are post 1980. It will probably prove to
be more widely distributed within the Highlands. Not listed
in Shirt (1987); status revised from RDB 3 (Falk 1991).
Threats Clearance of woodland for intensive forestry or
agriculture. Removal of any dead wood and old or diseased
trees which may support fungus hosts.
Management and conservation Retain any dead wood and
old or diseased trees, ensuring the continuity of these in the
future. Maintain any marshy areas or woodland streams
without disturbance.
Published sources Chandler (1988).
MYCETOPHILA BIALORUSSICA
A fungus gnat LOWER RISK (Nationally Scarce)
Order DIPTERA
Family MYCETOPHILIDAE
Mycetophila bialorussica Dziedzicki, 1884
Identification Chandler (1977a and c) figured the
ovipositor and male genitalia respectively.
Distribution Most records apply to the Scottish Highlands
but an isolated record from Cornwall suggests that it may
occur more widely in the west of Britain also: Lelant,
Cornwall (1912); near Carie (1987) and Kilvrecht (1995),
Rannoch, Pass of Killiecrankie (1979, 1987), Foss Bridge
(1974), Weem Castle Woods (1992), Camusurich Wood
(1992) and Craigmore Wood (2003), Perthshire; Logie,
(1909, 1913), Craigellachie NNR (1997) and Dulicht Wood
and Boat of Garten (2000), Elgin; Glen Affric (1999),
Dulsie (1982), Balnaught (2002, 2003) and Dell of
Rothiemurchus (2003), Easterness; Bohuntine, Westerness
(1997); Dingwall (1909) and Loch Eye (2002), East Ross.
Habitat Broad-leaved and mixed woodland.
Ecology Biology unknown. Larvae probably develop in
lignicolous fungi. Adults recorded from June to September.
Status Until recently a poorly known species, but sixteen of
the eighteen Scottish sites are post 1970 and it is probably
under-recorded at least within its Scottish range, being
evidently well established in Perthshire. Status revised from
RDB 3 (Shirt 1987 and Falk 1991).
Threats Clearance of native woodland for agriculture or
intensive forestry.
Management and conservation Retain any old or diseased
trees and dead wood, ensuring the continuity of these
habitats in the future. Avoid drainage of marshy areas or
disturbance of woodland streams.

MYCETOPHILA BOHEMICA
A fungus gnat LOWER RISK (Nationally Scarce)
Order DIPTERA
Family MYCETOPHILIDAE
Mycetophila bohemica (Laštovka, 1963)
Identification Keyed and figured by Laštovka (1963).
Distribution Mainly recorded from the central Highlands of
Scotland but also found recently in northern England and
Wales: Great Wood, Cumberland (1991); Pencelli Mire,
Breconshire (1997); Logie (1904, 1913), Inverdruie,
Aviemore (1967), Grantown-on-Spey (1991), Boat of
Garten (2002) and Randolph’s Leap (2004), Elgin; Loch
Einich (1967), Strath Farrer (1981), Cawdor Wood (1984),
Loch Garten (1982, 2002), Abernethy Forest NNR (1999),
Glen Coiltie, Culbin Forest and Craigellachie NNR (2002),
Easterness; Loch Achilty, East Ross (2002); Migdale Wood,
East Sutherland (1994, 2002). A record from Studley Royal
Park, Yorkshire, requires confirmation.
Habitat Broad-leaved and mixed woodland.
Ecology Biology unknown. This belongs to a group of the
genus where only one of the commoner species has been
reared and develops in myxomycetes, which themselves
require damp rotten wood as a substrate. Adults recorded in
June.
Status Until recently thought to be confined in Britain to
the Scottish Highlands, where there are fourteen post 1960
records, all but one of them post 1980. As it is now known
to occur in the north of England it may be assumed to have
a wider distribution in northern Britain but to be underrecorded.
Status revised from RDB 1 (Shirt 1987) and RDB
2 (Falk 1991).
Threats Clearance of native woodland for intensive forestry
or agriculture.
Management and conservation Maintain woodland in a
natural state, retaining any old or diseased trees and dead
wood, especially in damp shaded situations, which may be
essential for its larval development. Ensure that marshy
areas are retained and wooded streams are undisturbed and
remain shaded.

MYCETOPHILA CAUDATA
A fungus gnat LOWER RISK (Nationally Scarce)
Order DIPTERA
Family MYCETOPHILIDAE
Mycetophila caudata Staeger, 1840
Identification Keyed by Edwards (1925) and Laffoon
(1956). The male genitalia were figured by Landrock (1927)
and by Laffoon (1956).
