Trissolcus japonicus: An Egg Parasitoid of the Brown Marmorated Stink Bug (Halyomorpha halys)
A parasitoid is an organism that lives in close association with its host and at the host's expense, and which sooner or later kills it. Parasitoidism is one of six major evolutionary strategies within parasitism. Parasitoidism is distinguished by the fatal prognosis for the host, which makes the strategy close to predation.
