I think it's been demonstrated that insects release "semiochemicals" into the air for rapid communication. Similar chemicals common to other creatures are known as pheromones. (Of course, it could be dryads ...)

Of course, it could be dryads....

But only if you're determined to "mix metaphors." :^)

I think it's been demonstrated that insects release "semiochemicals" into the air for rapid communication.

But if your cosmology does not include the concept of chemistry, or considers it too reductionist, then you would be inclined to exhaust the search for garden fairies before turning reluctantly to conventional science.

I suppose cosmology does matter, which is why science has made progress in the last century or two.
