Gypsy moths aren't native insects, but they have been kept in check because of more than 20 natural predators, parasitoids and diseases that attack them in North America.

There are no population outbreaks in the autumnal moth further south in Fennoscandia, most likely due to the high abundance of generalist parasitoids that keep moth populations below outbreak levels [92].

Changes to the populations and population trends of species such as lemmings and forest insect pests are very likely to have far reaching consequences for the biodiversity of the vegetation they consume, and for their predators and parasitoids, as well as for ecosystem processes like nutrient cycling.

Trophic interactions with either the mountain birch host or its insect parasitoids are the most plausible mechanisms generating cyclic outbreaks in Epirrita.

However, the Arctic is an important global pool of some groups such as mosses, lichens, springtails (and insect parasitoids [13]) because their abundance in the Arctic is higher than in other biomes.

These outbreaks are important for predators, such as snowy owl (Nyctea scandiaca) and arctic fox, which both prey on lemmings, and parasitoids such as the wasp Cotesia sp., which lays its eggs in caterpillars of the autumn moth.
