AFB Certified Butterfly Farmers are those professional members who have taken the Advanced Lepidoptera Disease Prevention Course and have completed all course material and passed all the quizzes and final exam. The owners of these farms have taken the time to complete an intensive month-long course, edited by two insect pathologists and two OE specialists. They have earned the Disease Prevention Seal, which needs to be renewed every three years by taking the disease course and passing all quizzes and exam again.
We encourage you to purchase eggs, caterpillars, chrysalises, and adult butterflies from these farms. By purchasing butterflies from farmers who display the seal on their website, you can have confidence that these farmers have completed the course, practice disease prevention through good rearing practices, and know how to keep their stock clean and healthy by recognizing signs and symptoms of unhealthy stock. You are ordering from a knowledgeable, informed professional who understands what to watch for and can help you feel good that you are receiving healthy butterflies or caterpillars.
