The number of early instar larvae collected during surveys was much greater than the number of later instar larvae collected despite larger instars being more conspicuous, again suggesting that larval mortality by predation may be substantial. We frequently observed the aforementioned characteristic feeding damage on leaves during our surveys despite no larvae being found on the plant. We have also observed that the larvae are palatable to birds such as chickens (
