Since hatching began on the 17th and 18th March, I can't find any! There is negligible damage to the citrus and new shoots are not being touched!
I suspect the heat wave we had during the period Papilio anactus laid and the eggs hatching is responsible for such mortality. I don't believe any natural predation to be the sole cause of their disappearance.
It's possible Papilio anactus could still be active until May, but I doubt there will be another breeding event in my garden this year.
