I was very excited to find several Monarch caterpillars munching my milkweed plants this year. I then discovered a pest chowing down one of my guests. I removed the pest and watched my plants carefully. Unfortunately they began to disappear one by one til there were none left. I think it might have been birds, since they disappeared without a trace as opposed to insect pests. Does anyone have any thoughts about what may have happened and how I can prevent a reoccurrence next year?
