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).
Only a few larval species feed on plants; most are primary parasitoids of numerous arthropods at all life stages. They stand out as one of two hymenopteran families that include some species known to parasitize thrips. Eulophids can be found worldwide in diverse habitats (one is even aquatic, parasitizing water-penny beetles).
