For several years I’ve had a massive swamp milkweed at the edge of my pond….and never saw any Monarchs or their caterpillars show any interest in it….until a few days ago….but not on the massive mother plant, but on two tiny sprouts several feet away…one on each…and of course they had decimated them in a matter of days….I noticed one made it to the mother plant and has began its pupa stage….no idea where the other one went.
