Parasitoid
![](https://commons.wikimedia.org/wiki/Special:FilePath/Collinia_sp.jpg?width=300)
A parasitoid is an organism that spends a significant portion of its life history attached to or within a single host organism in a relationship that is in essence parasitic; unlike a true parasite, however, it ultimately sterilises or kills, and sometimes consumes, the host. Thus parasitoids are similar to typical parasites except in the more dire prognosis for the host.
