The species Lasius Flavus who live primarily underground actually build seperate chambers for their root aphids they keep underground. They have access to root aphids that create honeydew from grass roots, but of course also many other plants, how efficient is that? It's even suggested through research that Lasius Flavus maintains the same principle as humans when it comes to keeping cattle; the young and most efficient aphids work for honeydew and those that are too old or not working hard enough are butchered for food. There is a world or miracles beneath our feet and most people will never become aware of it.
I currently have 2 colonies of L. Flavus that I will be creating setups for that is going to recreate the underground environment so I can see what they do and how they do it. Still haven't figured out an easy way to obtain root aphids other than stealing plants + roots from the lasius flavus colonies in the wild and hope there is some of these aphids on the roots.
