Finding a monarch that won't make the long journey south is always tough. As we enter peak migration, we hope to see every butterfly take flight for Mexico, but moments like these are a reminder of just how fragile their journey really is.
This little guy is affected by Ophryocystis elektroscirrha (OE) which is a microscopic parasite that infects monarchs as caterpillars and disrupts their metamorphosis. Unfolding its wings properly requires immense energy and healthy cellular development; when OE infection rates are high, monarchs emerge too weak to expand their wings, leaving them unable to fly.
Moments like this offer a powerful reminder of why thoughtful, intentional stewardship matters so much. Planting native milkweed (Common, Swamp & Butterfly) is essential to their success, while keeping non-native tropical milkweed out of our gardens helps prevent the buildup of parasites. Additionally, if you rear monarchs, avoid releasing OE-infected adults into wild populations and always thoroughly sanitize containers with a bleach solution to protect future generations.
