u're right. The "proboscis" is clearly visible even for me, but I wasn't
sure I remembered how a wasp "mouth" looks like. I saved the "wild flower"
photo and used the "magnifier", and the wings appear to me to be placed like
those of a fly rather than those of a wasp, and also less elongated.
Besides those, as I'm not a specialist, I would have to do at least some
research before I could tell. But as the photos you pointed to show
clearly, the wasp "face" is much more elongated, as are its wings. It's not
clear the wasp has 2 sets of wings in the photo under the 3rd link though.

Thanks for sharing your knowledge

aside from the discovery, what is that fly on the flower?

It's a syrphid fly or hover fly, family Syrphidae.
[snip]

I would have sworn it was a wasp... how can you tell it's not?

They look very different in detail.

In the photo you can clearly see that it has a fly's head, antennae
and mouthparts, all of which are clearly different from a wasp's.

Apart from beelike or wasplike coloration and sometimes behavior,
syrphid flies are rather typical flies in body structure and wings.
Again, the details are very different from those of wasps and bees.

If you had specimens in front of you instead of just a web page
news photo, you'd easily see that the fly has just two functional
wings instead of two pairs of wings as in wasps [the hind pair of
wings in true flies (order Diptera) are represented by small
appendages called halteres (not visible in the photo)], and a
flylike proboscis [visible in the photo] for mouthparts instead
of a wasplike set of biting jaws.
