The research of nocturnal Macrolepidoptera using Jalas automatic light traps was carried out on Notigale and Laukenai raised bogs in 2000. The latter site is small (64.1 ha) and overgrown with dense pines and shrubs, while the former site is much bigger (552 ha) and quite open. A total of 11224 Macrolepidoptera specimens belonging to 352 species have been registered. 221 species were common for both communities. 16 stenotopic bog species (5 of them tyrphobiontic) were found on Notigale, and 13 (4 of them tyrphobiontic) on Laukenai bog. 3 stenotopic species (Scopula virgulata, Syngrapha and Litophane lamda) were recorded only on Notigale raised bog. Total abundance of stenotopic Macrolepidoptera species was 20.9% on Notigale, and 32.5% on Laukenai bog. Each Lepidoptera community was composed of 22 species with an abundance of equal to or greater than 1 % of the total catch. Lycophotia porphyrea (13% of all individuals) and Nola aerugula (12.8%) were dominant species in Notigale, while Nola aerugula (15%) and Hypenodes humidalius (9.2%) in Laukenai Macrolepidoptera community.
