Martin:

I believe wasps eat mostly other other insects.

Could be they are after insects in the flowers like aphids who produce honeydew that the wasps feed on as well.

Hi everyone,

this summer starts to feel somewhat Hitchcock-style - this time it's the
wasps that run amok. With them it can't be hunger, because there are
tons of fallen apples in the gardens around. When they started to act
peculiar, they chewed on green seed heads of Centaurea montana - fine
with me, because those tend to be invasive. Then they found Tigridia
Pavonia...
