I should want to be sure : is that "bubbles", full of gas, or "dropplets" full of liquid ?

If I remember well, there were also some photos of non-dipteran species blowing bubbles in this topic. Because download speed is back to horrendous here, I'm nog going to check if I'm right though. Anyway, a couple of months ago I photographed a large Surinamese katydid (Orthoptera, Tettigoniidae) with a large bubble. My photo series shows that he/she sucked it back up, then made it larger again. This was in the evening after sundown at about 450m altitude. The place (Brownsberg) becomes rather chilly at night, and often misty as well, and I don't think thermoregulation or evaporation are viable explanations in this case. I don't know which explanation would be viable though...

This seems to be an halictic bee manipulating nectar droplets to reduce moisture. While I was taking the pictures, the bee moved continuously her tongue in and out about twenty times before it flew away. This is the first time I have seen a bee doing this drying and ripening process with her tongue. There are several pictures of bees processing nectar with a droplet in her mouth, as if they were simply bubble blowing . But in this case the bee seems to evaporate more water from the droplet by expanding the proboscis to full length and exposing a larger droplet surface to the sun.

Another nighttime blower, this time a walking stick (Phasmatodea). Photographed on the Brownsberg in Suriname.

Here in Brazil they blow bubbles in very weird situations (also nighttime)

It seems that at least the body cooling theory seems to be confirmed now, look e.g. here (literature at the bottom): https://rcannon99...nt-page-1/

In the light of evolution, it is very well possible that certain diptera-groups (probably closely related to eachother) have developed this behaviour. It could be a mix of reasons. Or the main reason may be digestion, with an extra opportunity to control bodytemperature.
To get a better idea of this, best we can do is to make solid observations in the field, like I suggested above.

I know that both calyptrates and acalyptrates can 'do the bubble'. I cannot recall any orthorrhaphous brachycera and even deep searching my mind I do not recall having seen syrphids do it.

I think it may simply also have to do with the structure of the mouth parts that enable the flies to bubble or not. And that, in its turn, is determined by evolution, as related taxa probably have the same kind of mouth parts, unless evolution took the a step further.


Very interesting thread !
If it can be a any help,
For Brachycera I've pictured this Sepsis sp female (probably Sepsis fulgens with 2 dc but on certain pictures I can see yellow on the legs) :
