first let me start by saying, it's always a pleasure to disprove what the books tell you (and especially that damn wikipedia...a place for half assed information)
today I documented a Zebra Swallowtail (Protographium marcellus) laying eggs on Annona dioica, Annona cornifolia, and A. muricata.
all the info I've seen, says that they feed exclusively on Asimina species.
Well I'm here to tell you, that's not true.
Here is proof.
a female hovering around Annona cornifolia, looking for a place to lay.
about to lay an egg on A. cornifolia
difficult to see, but there is an egg on the new growth of this grafted A. dioica
easy to see the egg, on the new growth of A. cornifolia (this seemed to be the butterfly's favorite tree, it laid most of it's eggs on cornifolia)
