Observation - Chalcid wasp (cont.). Description: The present individuals were operating among ivy on a sheltered tree that was temporarily exposed to light from late morning sun. Even if a species name still can’t be put to them, I wonder if it can be said if they are likely to be males or females

The present individuals were operating among ivy on a sheltered tree that was temporarily exposed to light from late morning sun.
Even if a species name still can’t be put to them, I wonder if it can be said if they are likely to be males or females and, if they are parasitoids, what the possible hosts might be.
