I breed end bumblebees in the end. It stands to reason that the temperature and humidity of the end are the most suitable. It is true after measurement, but after putting it in the bumbliary, it died soon and there was no product. I don’t know this. WTF?!

It has been resolved that the inside bumblebees needs a roof and a wall of at least 7x7 In addition, the centrifugal recipe of Royal comb seems to be missing something (where is the royal jelly?)
