Tiger Longwing Butterfly laying eggs

Now I know why the Tiger Longwing Butterflies, keep coming to my garden they like to lay their eggs at the end of the tendrils of the Passion flower, after that the tendrils curl and completely hide the eggs, the problem is... a large preying Mantis lives there and... sorry but I have been helping the butterflies so they do not get caught by it...I am learning so much about Butterflies in my garden!!
