cecropia

[Ted Ryznar]

I am currently raising some cecropia moths. I have always read that they
will never switch host plants once they start eating a particular food
plant. Some of  them started feeding on poplar but all but 2 have now
switched to apple. They are in their 2nd instar. Also it doesnt seem to
matter which particular type of apple leaves are presented to them. They
seem to switch easily from one type of apple leaf to another. Has anyone
else every expierenced this type of behavior?  also I have read that they
have a tendency to die when they go into their last instar when raised in
captivity. anyone have any comments concerning this and how it could be
prevented. thanks for your time.
