Last resort..

A couple of weeks ago I built a 'teepee' over a tall swan plant to try and protect any monarch caterpillars from the paper wasps (I hadn't seen any eggs but knew there would be some there) By the time I went away last week there were a number of half grown caterpillars. When I returned home yesterday I found the plant stripped of all foliage,  ten chrysallis's hanging and about the same number of half grown caterpillars which I transferred onto other plants.This morning I found these two devouring this seed pod, the only thing left on the plant.
