The larvae of very few species feed on plants, but the majority are primary parasitoids on a huge range of arthropods at all stages of development. They are exceptional in that they are one of two hymenopteran families with some species that are known to parasitize thrips. Eulophids are found throughout the world in virtually all habitats (one is even aquatic, parasitising water-penny beetles).
The larvae of only a few species consume plants, but most are primary parasitoids on numerous arthropods at all stages of growth. They are unique because they belong to one of two hymenopteran families that include some species known to parasitize thrips. Eulophids can be found globally in various environments (one is even aquatic, parasitizing water-penny beetles).
