"I have 7 monarchs I am raising in the house. I have been reading alot
of info on the internet about when they go into pupa stage. Mine are
47mm long (+or-) and are eating like pigs. I fear I will run out of
milkweed before they change."
Most of the larvae I have raised from eggs will pupate ten days after the
egg hatches. If your larvae are 8-9 days old, you have only a day or so to
go before they spin their little button, hang upside down, and feed no more
on leaves.
On the other hand, of the 20 or so larvae I reared this summer, almost half
were parasitized with multiple tachinid larvae, which emerged when the
monarchs hung upside down to pupate.
