Broken Wing

September 21, 2015
By Kathy Keatley Garvey
Broken Wing belongs here. And that's a good thing, because he won't live long. A male monarch that we've nicknamed Broken Wing due to a predator mark, hangs out on our milkweed, butterfly bush and Mexican sunflower (Tithonia). He's probably looking for a meal and a mate.

Estimating armyworm injury

September 16, 2015
