The ichneumonid wasp Ctenochares bicolorus was reported for the first time in the Netherlands in 2015 and in Belgium in 2019. These records are the first for continental northwestern Europe. The specimens are imported, probably with vegetables. The species, a parasite of Lepidoptera, originates from Africa, but has been introduced in southern Europe and has settled there. It seems possible that Ctenochares bicolorus will form populations in northwestern Europe in the future, especially in greenhouses. |
