Do Ants Secrete the Fluid?

Honeybees don't secrete fluid like ants do. So where did they get this from? I'd like to ask many, many ant species as he said about 15,000. We initially found this in our main lab model system which is called the Clonal Raider ant but that species is a little bit unusual. It turns out that they all secrete this people fluid and so it seems like this evolutionary novelty really arose very early in ant evolution.
