Matilla and Harris did mark bees. It is very easy to do. Could you please do so this fall and let us know the results?
If I understood what you want to mark might be able to make time. Trying to understand what we are marking. Just to see how long bees live?? Or say an aug bee and a sept bee and an oct bee?? Not sure how I would be identifying when winter bee formation actually starts.... open to suggestions and a plan.
