No because it's entirely voluntary on the wasps part

Vegetarian is fine, there is no flesh. Vegetarianism is typically a dietary restriction, rather than a philosophical one.

Vegan: it depends. Cultivating figs may be seen as expotation, like bee's honey is; regardless of the insect's actual life or wellbeing. Each individual person decides what counts as vegan.

I don't see the point in this level of specificity, because by eating anything at all you consume fungal spores, tiny mites, microbes etc. Plants are also alive. So there is clearly a line where life is permittably consumed.

If 'experiencing suffering' is that line, insects do not seem capable of it, only responding to basic stimuli. I once watched a one trying to eat its own partially severed head, turning it in its front legs while its mouth parts rapidly twitched. It evidently had no comprehension.
