Monarch fecundity


These are the only such data that I am aware of collected from observation of a single butterfly in a controlled environment.  Monarch biology was designed to overcome predation, but apparently it is less capable of coping with modern-day habitat loss caused by herbicides.

From Journey North, where the maps show that monarchs have been sighted at our latitude.  The milkweed in our garden is waiting for them.
