Microdiprion pallipes

Microdiprion pallipes (FALLÉN, 1808) Beinn Eighe NNR, NH0064, Wester Ross, native pinewood, 1 ♀, 11.v.-13.vi.1988, Malaise trap, leg. I. MacGowan (RSME). Both the above individuals (see also Table 1) are extremely pale. The lateral parts of the abdominal terga and most of the sterna are bright yellow. In the field, the Claybokie specimen was initially mistaken because of its pale colouration for Monoctenus juniperi (Linnaeus, 1758). However, the female of M. juniperi has at most a band of orange-brown along the lateral margins of the terga. Benson (1959) referred Scottish populations of M. pallipes to ssp. pallipes, found also from northern Fennoscandia south to around Berlin in Germany (Forsslund 1960). The nominate subspecies was considered to be replaced by M. pallipes ssp. politum (Klug, 1812), adults of which are much darker, in Alpine and pre-Alpine Europe. Mallach (1973) discussed some of the problems attached to the distinction of these putative subspecies. The description by Enslin (1917) of variability in colouration in Lophyrus (M.) pallipes still seems very fitting.Published as part of Liston, A. D., Knight, G. T., Heibo, E., Bland, K.

Athalia rosae

Athalia rosae (LINNAEUS, 1758) Roseburn, 2 ♀♀, 20.vi.2010, leg. Liston (SDEI, RSME). Liston (2008) discussed the recent reappearance of A. rosae in Scotland. The individuals above (see also Table 1) were found in vegetation in which the known larval hosts (principally cultivated Brassicaceae) are largely absent. Perhaps these three females were part of a dispersal event. During the preceding days, a strong wind blew from the North. Is it chance that the first records of A. rosae in Scotland since 1859 (Berwickshire) were to the North of Edinburgh (St. Andrews, Fife, 2007; Liston 2008)? It seems worth noting that all records of A. rosae in Scotland have until now been from the East Coast and that no male has yet been found.Published as part of Liston, A. D., Knight, G.

Tenthredo moniliata Klug 1817

<i>Tenthredo moniliata</i> KLUG, 1817 <p>Orkney, Hoy, Quoyberstane, HY 4612 (111), 1 ♀, 22.vi.2009, leg. Bland, det. Liston.</p> <p>Malleny Woods, (artificial?) pond, 1 ♀, 12.vi.2010, leg. Liston.</p> <p> As noted by Benson (1952), <i>Tenthredo moniliata</i> is in the British Isles exclusively associated with <i>Menyanthes trifoliata</i> L. [see also above under <i>T. ignobilis</i>]. In the Highlands <i>T. moniliata</i> is widespread, although not previously recorded in Orkney. Around Edinburgh and in other areas of the British mainland south of the Highlands it has become restricted to a very few sites (except in Wales, where it is local but widespread, as in Ireland). Its sole host has suffered numerous local extinctions, as for example is well documented in the Edinburgh area: compare Martin (1934) with BSBI (2010). The colour form with mainly black femora decribed by Cameron (1878) as <i>T. lachlaniana</i> falls within our present concept of variability in <i>T. moniliata</i>. The status of <i>T. moniliata</i> as regionally endangered in lowland Britain is similar to its status in the lowlands of Central Europe, but in Austria and Germany the situation is complicated by the existence of populations (or perhaps as yet undistinguished sibling species) on <i>Origanum</i> and <i>Pulsatilla</i>.</p>Published as part of <i>Liston, A.

Pachynematus clitellatus

Pachynematus clitellatus (SERVILLE, 1823) Dumfriesshire, White Coomb, 4 ♂♂, 19.vi.2010, leg. Liston. Treated in the sense of Taeger & Blank (1998). Male specimens from Meall nan Tarmachan, White Coomb and Corrie Fee, leg. Heibo and Liston key to P. kirbyi (Dahlbom, 1835) in Benson (1958) and might well be considered to represent a different species. These were swept from marshy land dominated by Carex, whilst P. clitellatus s. str. is also found on dry areas and is attached perhaps only to various Poaceae.Published as part of Liston, A.

Dolerus brevicornis ZADDACH 1859

Dolerus brevicornis ZADDACH, 1859 Baddoch, 1 ♀, 4.vi.2010, leg. Blank, Liston & Taeger. Dolerus brevicornis was only recently distinguished from D. asper Zaddach, 1859 (Heidemaa et al. 2004). Both species occur in the British Isles, but their distribution needs clarification. The above records are the first of D. brevicornis from Scotland.Published as part of Liston, A. D., Knight, G.

Pachynematus clibrichellus

Pachynematus clibrichellus (CAMERON, 1878) Dumfriesshire, White Coomb, north of summit, ca 750 m, 1 ♂, 19.vi.2010, leg. Liston. Recorded by Benson (1958) from “Perths., Inverness, Angus, Sutherland and Caithness, mostly on mountain tundra, but at sea level at Wick in Caithness[..]”, but also found by Nelson (1971) at high altitudes in the northern Pennines of England. It is therefore of little surprise that Pachynematus clibrichellus has now been found on one of the highest hills in the Southern Uplands of Scotland, where a few other very local occurrences of ‘arctic-alpine’ sawfly species are already known (Liston 1983b; 1984, record refers to Pontania herbaceae).Published as part of Liston, A.

Tenthredo mandibularis * Fabricius 1804

Tenthredo mandibularis FABRICIUS, 1804 Edinburgh; Roseburn: 3 ♂♂, 16.vi.2010, leg. Liston; 1 ♀, 17.vi.2010, leg. Liston. Midlothian, Gorebridge, Gore Glen, 1 ♂, 18.vi.2010. Edinburgh, Juniper Green, W. of Leith, 1 ♀, 19.vi.2010, leg. Liston. Angus, 3 miles North of Kirriemuir, 2 ♂♂ (many more individuals seen, but only these two taken as vouchers), 23.vi.2010, leg. Liston (SDEI, RSME). These Scottish adults were collected exclusively from stands of Petasites hybridus, which seems likely to be the larval host. According to Benson (1952) Tenthredo mandibularis is “Recorded from Dorset, Hants., Essex, Kent, Beds., Oxon., Yorks., and Cheshire. Probably occurs wherever the Petasites is abundant in England.” No previous records from Scotland of this conspicuous and distinctive species are known. Published hostplant records refer only to Petasites, usually without naming a species (Lorenz & Kraus 1957), or identify only P. albus as a host (Pschorn-Walcher & Altenhofer 2000). According to observations apparently made only by Brischke (1883), but often repeated in subsequent publications without citation of the source, Petasites officinalis (a synonym of P. hybridus) and Tussilago farfara are hosts. Tussilago farfara is the main or only host of T. mandibularis in Norway according to Heibo & Lönnve (2005).Published as part of Liston, A. D., Knight, G. T., Heibo, E., Bland, K.
