How to tell whether a silkworm chrysalis is alive or dead?
Let me answer you;
First; First of all, you need to know whether the pupa in the cocoon is alive or not.
Second; Whether it has passed the hibernation period!
Third; Whether it reaches a certain accumulated temperature!
Now that you have opened its shell, take it out and see that there is a temperature sensitive plate on its head; If the temperature sensing plate is white, it is alive. If it is black, it is dead. If it is yellow, it means it is warm. If it is red, it will soon have moths. Are you satisfied with my answer?
