With certainty, I only could tell females of both species from measurements of the ovipositor blade (aculeus). However, there are some unexpressible differences in the wing crossbands (more or less oblique) showing that this is
acrolophi, indeed. But since there was
Acinia corniculata in the meadow, both
acrolophi and
jaceae might occur in there.
