Isolated peat bog habitats harbour a unique diversity of cold adapted insects. Stenotopic highly specific Lepidoptera that feed on the typical bog plant Vaccinium uliginosum were parasitized by generalists of Braconidae and Ichneumonidae.The tyrphobiontic Lepidoptera is connected with generalist-parasitoids. In a disturbed peat bog and under impact of biological invasions, the penetration of alien and opportunistic insects is obvious. An example of invasive plant Frangula alnus and associated insects is given. Host specificity of parasitoids is typical for widely distributed, easy available and abundant hosts, but paleorefugial, local and rare host-Lepidoptera seem to be associated with parasitoids of relatively wide ecological amplitude.
