Many plants produce a fragrance that attracts useful bugs and critters. Useful means that they offer some benefit to the plant. So all over the place, greenery is pumping out Sniff-Stimulants.
Rhinos are not official connoisseurs, but We know a lot about scent, both production and interpretation. What is a fact is that Scent travels in tiny globules, wafted by the breeze.
However, Scent is not uniform or static. ‘Sweet & alluring’ today can turn into ‘disgusting & revolting’ any time it wants to. We have a long history of being fooled, but Rhinos are working on the problem. In truth, our success thus far has been modest. Good luck to Us.
