The composition of the ichneumonid and braconid wasp community of a native, montane forest on the Hawaiian island of Kauai was examined. Wasps were sampled for two consecutive years using a malaise trap. All but one of the 17 species captured are lepidopteran larval/pupal parasitoids. Half of the species captured are native to the Hawaiian islands, 37 percent are adventive alien species and two species are purposefully introduced biological control agents. However, less than 10% of the 2.017 individuals captured represent native species and the two biocontrol species accounted for 50% of the entire catch. The composition of this community is shown to be highly unusual in comparison to natural, continental ichneumonoid communities. The conservation implications of this predominantly alien community are discussed.
