Infected Or Parasitized Monarch Chrysalises

Whether these were infected or parasitized Chrysalises, I’m not sure, maybe a combination of both.  You can see the Chrysalises all have small holes in them, normally indicating they have been parasitized.

Here’s where I could use some guidance.  Although the Chrysalises were in our outdoor Butterfly Enclosure, and were theoretically protected from predators, there was a wasp in the enclosure nearly every day.

Mystery Wasp In Butterfly Enclosure

The strange part was we would release this wasp every time we found it in the enclosure, then the next day another wasp (or the same) would be back in the enclosure.

Can anyone identify this wasp and tell me if this wasp would parasitize the Chrysalises?

UPDATE: Valerie over at Evanson Art And Design was kind enough to tell me the wasp above is likely a Ichneumon Wasp which do indeed parasitize Butterfly Chrysalises.
