Braconid parasitoid Cotesia glomerata, which was accidentally introduced into Canary Islands became real threat to the Canary Island Large White butterfly (Pieris cheiranthi). The multiple confirmation of the origin of the introduced parasitoid (morphology, DNA, ecology) suggests that these opportunistic parasitoids might be a serious danger to native isolated fauna. Such model relationships can be found in isolated paleorefugial habitats of the central European peat bogs, which are historical habitat islands of unique local taxa. A recent discovery of some opportunistic parasitoids attacking tyrphobiontic Lepidoptera in several isolated bogs of South Bohemia suggest these wasps might invade isolated habitats and cause serious population destruction of paleorefugial hosts.
