I found a dead Acronicta rumicis larva on the 29th of September in Barcelos, Portugal. It was parasitized by wasps. I think they may belong to Braconidae, what is your opinion? As you can see, the two adults of the top photos are different from each other and both seem to be female. Different species?
The form of the areola seems to me rather a rhombus what brings me to Mesochorinae, in Taxapad one speaks ex- rumicis Mesochorus semirufus.....mais it is only assumption!!!!
Compares well with the type genus images on this Japanese site http://cse.naro.affrc.go.jp/konishi/mokuroku/mesoch.html.So either Campopleginae or Mesochorinae with Mesochorinae the best assumption.Maybe someone working on Acronicta will know.The keys are hopeless for me.
