I agree. If it is an European species (always an if in greenhouses), it must be laetus female.
The species is generally more orange that yellow, as shown in the picture.
Laetus (or laetus-like) specimens are more often found in greenhouses (to be published next month in Entomologische Berichten, Amsterdam).
