Table 6. Sex ratio and median day of species taken in 100 specimens or more in the light traps in the Cal/una heath at Austre Loftmyra and on the grassland at Austervagen in 1978. Median day have been calculated for the females only in species were 25 or more females were caught. The median day given for Pachycnemia hippocastanaria refer to the spring generation. ~ ) SPECIES n %9 cl Median day 9 Geometridae Entephria caesiata 185 10,3 15.7 Eulithis testata 379 4,0 18.8 E. populata 188 4,3 9.8 Thera cognata 2841 8,6 3.8 5.8 T. juniperata 171 1,2 13.10 Perizoma didymata 150 4,7 8.8 Eupithecia pusillata 291 22,7 16.8 17.8 Pachycnemia hippocastanaria 242 14,0 19.5 22.5 Alcis repandata 179 8,4 18.7 Gnophos obfuscata 188 8,5 26.7 Noctuidae Euxoa obelisca 181 6,6 14.8 Rhyacia grisescens 128 14,1 9.8 Chersotis cuprea 159 22,0 13.8 15.8 Noctua pronuba 381 8,9 12.8 14.8 N. comes 194 12,4 12.8 Paradiarsi glareosa 171 22,8 3.9 6.9 Lycophotia porphyrea 2063 13,9 16.7 27.7 Diarsia mendica 400 14,6 17.7 29.7 Xestia castanea 183 11,5 17.8 X. xanthographa 169 10,1 17.8 Cerastis rubricosa 141 5,7 30.4 Ceramica pisi 107 3,7 5.6 Cerapteryx graminis 904 11,9 6.8 9.8 Orthosia gothica 546 9,7 1.5 6.5 Aporophyla nigra 595 23,7 5.9 6.9 Amphipyra tragopoginis 120 20,0 1.9 Apamea monoglypha 433 28,6 2.8 6.8 A. lateritia 329 14,9 2.8 3.8 Photedes minima 124 0,8 23.7 Amphipoea IUfens 762 8,7 22.8 19.8 A. crinane,lsis 594 7,7 14.8 19.8 Celaena haworthii 228 0,4 10.8 Stilbia anomala 235 3,0 8.8 were lower than on the neighbouring grassland. This difference is undoubtedly rootet in the fact that the grassland has a richer flora (0vstedal 1978), and more Macrolepidoptera can hence find suitable foodplants in this habitat. However, while the species richness among Noctuidae in the heath was only slightly lower than on the grassland, the difference between the two habitats was more pronounced in Geometridae. S0rensen's quotient of similarity also shows that the Noctuidae faunas in the two habitats are more similar than the Geometridae faunas. This difference might be connected with the windy climate. Based on light trap catches Williams (1940) demonstrated a strong negative correlation between wind velocity and the flight activity of insects, and also that Noctuidae are less affected by wind than the average other insects. The generally more slender, broad-winged Geometridae might therefore be more vulnerable than the Noctuidae in the open wind exposed heathlands on northern Sotra, and Geometridae from neighbouring habitats might therefore generally be more reluctant to fly across heath terrain. The higher similarity between the Noctuidae faunas in the heath and on the grassland, as shown by S0rensen's quotient, might accordingly be an expression of a higher dispersal ability of Noctuidae in a windy climate. The flight activity of the Geometridae inhabiting the heaths seems, however, not to be seriously supressed by wind, as the family constituted 40 % 101
