Another Gasteruption visitor on the Parsnip (Pastinaca-sativa). This time the photo’s offer enough characters to determine the species: Gasteruption assectator .
The parsnip flowers are a success looking at the ‘large’ amount of Gasteruption wasps visiting them in a relative short time after introduction. Now I’m curious whether other families will find the flowers appealing as well as those are yet to be seen.
