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

1. Carabid beetles – Some carabid beetles (e.g., Lebia) have parasitoid larvae that develop on pupae of other insects. Correct.

2. Centipedes – Centipedes are predatory arthropods; they are not recognized as a group having parasitoid species in standard entomological classification. My earlier inclusion was a factual error. Incorrect.

3. Flies – Many flies, especially tachinid flies, are classic parasitoids of other insects. Correct.

4. Termites – Termites are eusocial detritivores; they are not known as a group containing parasitoid species. Parasitoids may attack termites, but termites themselves are not parasitoids. Incorrect.

5. Wasps – Parasitoidism is very common in wasps; ichneumonids, braconids and chalcidoids are standard examples. Correct.

So, parasitoid species are found in three of the above: 1, 3 and 5.
