no. 2 (IO %) in the heath, and as no. 8 (4 %) on the grassland. On the grassland A. crinanensis (Burrows, 1908) ranked as no. 2 (10 %), while in the heath it only ranked as no. 19 (I %). The different occurrence of these morphologically similar species is probably due to A. lucens preference for humid habitats (Hoffmeyer 1962). The wet areas in the heath undoubtedly provide favourable conditions for this species. Both species are common and widespread in Western Norway. Three species, Celaena haworthii (Curtis, 1829), Xestia castanea (Esper, 1796) and Noctua comes (Hiibner, 1813) were taken in large numbers only in the heath. C. haworthii ranked as no. 6 (4 %) in this locality, X. castanea as no. 8 (3 %) and N. comes as no. 9 (3 %). C. haworthii is taken in bogs in most parts of Western Norway. X. castanea is more restricted to the coast where it is found on heath terrain. N. comes is distributed in the lowland all over Western Norway, but seems to be common only along the coast. Two species, Chersotis cuprea (Denis & Schiffermiiller, 1775) and Photedes minima (Haworth, 1809) were taken in large numbers only in the traps on the grassland. C. cuprea ranked as no. 10 (3%) in this locality, while P. minima ranked as no. 12 (2 %). P. minima is common and widespread all over Western Norway. C. cuprea is also distributed all over Western Norway, but is most common in the inlands. Aporophyla nigra (Haworth, 1809) and Stilbia anomala (Haworth, 1812) are typical for the coastal areas, allthough single specimens of both species have been taken in inner Hordaland. A. nigra ranked as no. 4 in both localities, constituting 7 % and 5 % of the material from the grassland and the heath respectively. S. anomala ranked as no. 11 in the heath and as no. 13 on the grassland constituting approximately 2 % of both sets of material. ~ '0 '0 '0 A M A 5 o N Fig. 6. Light trap catches of Macrolepidoptera, as per cent of whole annual total per ten-day period, on the grassland at Austervagen in 1978. Flight periods The light trap catches taken on the grassland at Austervagen in 1978, divided in ten-day periods, are shown in Fig. 6. The frrst specimens arrived in the beginning of April, and no further specimens were taken after the middle of November. Largest catches were made in early August, with a smaller peak in late April - early May. The flight periods of Geometridae species taken in more than 100 specimens are shown in Fig. 7; the catches from the heath and the grassland have been combined. Most of the species have flight periods in late summer and early autumn. The duration of the flight periods varied from one and a half to nearly three months. The median day of the flight period of the different species, i.e. the day when 50 % of the specimens had been caught, are listed in Tab. 5. For most of the species the median day falls in the last third of July and the fIrst two thirds of August. I Thera juniperata had a late and vrry short flight period, lasting from 5 October to 15 November. Pachycnemia hippocastanaria is bivoltine on Sotra. The dominant spring generation were on the wing from 15 April to 10 June, while a few second generation specimens were caught in September and October. Among the Noctuidae species taken in more than 100 specimens there are two species, Cerastis rubricosa (Denis & Schiffermiiller, 1775) and Orthosia gothica (L., 1758), which fly in the spring (Fig. 8). Both had flight periods that lasted for about two months with median days in the last day of April and the fIrst days of May. Ceramica pisi (L., 1758) had a very long flight period, lasting from I0 May until 5 August, with the median day in the beginning of June. Several of the species flying during the summer, like Noctua pronuba (L., 1758), Lycophotia porphyrea, Cerapteryx graminis, Apamea monoglypha (Hufnagel, 1766) and A. lateritia (Hufnagel, 1766) also have long flight periods lasting for more than two and a half month, most of them with median days in the beginning of August. The majority of the Noctuidae started to fly in late summer and early spring, and several of these species, like Euxoa obelisca (Denis & Schiffermiiller, 1775), Chersotis cuprea, Xestia castanea, X. xanthographa (Denis & Schiffermiiller, 1775), Amphipoea lucens, A. crinanensis and Stilbia anomala, had rather short flight periods lasting from one and a half to two months, with median days in the middle ofAugust. Three species, Paradiarsia glareosa (Esper, 1788), Apo 96
