New parasitoid wasp likely uses unique saw-like spines to break out of its host body

(Pensoft Publishers) A newly discovered parasitoid wasp species from Costa Rica might be only slightly larger than a sesame seed, yet it has quite vicious ways when it comes to its life as an insect developing inside the body of another. Most likely, it uses its unique saw-like row of spines on its back to cut its way out of its host. The study is published in the open access Biodiversity Data Journal.
