I have been breeding and raising Monarchs in large numbers for 3 years now. In
my first (inexperienced) year, I observed 5th instar larvae cannibalizing newly
formed pupae in an overcrowded cage. I assume this was directly related to
overcrowding since thinning the numbers of larvae per cage seems to have
eradicated the behavior. It is interesting that the hardened older chrysalides
I have not personally observed larvae consuming ova but I normally have
discrepancies between the number of ova collected and the number of larvae a
week later. I'd estimate a loss of about 10-15%.
It's an interesting concept...deliberately eliminating future competition...if
you find any research on it, please let me know.
