My take: it's a defensive move. At least grasshoppers and some sawfly larvae use regurgitated food as a weapon.

I have not really noticed it in 'true' flies but in some Nematocera. Since many of the flies observed when blowing bubbles are at rest, I do not think defence will be the major explanation, though I will not rule it out.
