Only way to do it and get right nearly 100% is to expose the pupa and check
the abdominal segments.  If you don't want to do that you can weigh your
cocoons.  Most of the heavier ones will be females.  Some will be tough to
tell though and the occasional large male or diminutive female lowers the
odds a bit that you are going to get it right.  Good luck.
