Consider the following: 1. Carabid beetles 2. Centipedes 3. Flies 4. Termites 5. Wasps Parasitoid species are found in how many of the above kind of organisms?

Parasitoid species are commonly found among certain Carabid beetles (some Carabidae have parasitoid larvae), Flies (Diptera — e.g., Tachinidae are a major family of parasitoid flies), and Wasps (Hymenoptera — including Ichneumonidae, Braconidae, and Chalcidoidea are the largest parasitoid groups). Centipedes are predators, not parasitoids. Termites are detritivores/wood-feeders and are not parasitoids. Hence parasitoid species occur in three of the listed groups: Carabid beetles, Flies, and Wasps.
