Hi,
is it possible to determine the wasp more precisely on the basis of the images and the information about the host and to assign it to a subfamily?
On June 20th I found a caterpillar from the family Gelechiidae. The genus was determined in the Lepiforum as Helcystogramma, most probably H. lutatella or rufescens. The caterpillar has retreated into a rolled up leaf and pupated.

On July 9th the 6 mm long wasp shown here hatched from the pupa.

Hi Marion, what is the length of your wasp? I think it could be a male of Pimplininae?

Hi Eric, thank you for answer. The length of the wasp from the head to the tip of the abdomen was 6 mm. It hatched from a 7 mm long pupa.
Do you mean Pimplinae?

Sorry - yes, I meant Pimplinae, but I'm not sure, yet!

Thank you very much. It seems to be very complicated, because there are also a lot of small subfamilies.
I found a key to the subfamilies of North and Central American Ichneumonidae

What about a Metopiinae rather than a Pimplinae?

Metopiinae is a very good idea, thank you!
Looks like Exochus sp. or Hypserica sp..
