Lovely shot Paul. I see you have the Mexican sunflower
Yep, GMO's crops modified to stand the use of more pesticides /herbicides has helped kill off the host plant, milkweed. Of course there are varying opinions on this being one of the causes. You also have more fields being planted with soy and corn for use as ethanol thereby reducing the amount of milkweed.
In addition they think that several years of drought in Texas made it difficult for the Monarchs to find food on their migratory route. Also the illegal logging causing deforestation in Mexico.
Lots of unintended consequences at the hand of man combined with mother nature.
