Milkweeds are a very important group of plants for pollinators, especially for the monarch butterfly. There are 12 species of milkweeds in Wyoming - though three of those are rare. Part of the goal for this program is to find out which species, if not all of them, provide the monarch caterpillar with its critical food source. Milkweeds are often considered a weedy species and are targeted for spraying in pastures and along ditches. However, they are important assets to monarchs, and do great in garden settings!
You can identify milkweed species based on their location in the state, leaf shape, flower color, and other hints.

Let us send you a Biodiversity Institute published booklet to help you identify monarch's (and thier look-a-likes) and the milkweed species found here in Wyoming. The booklets are free, let us know how many you need.
The Monarchs and Milkweeds program is designed to work with you - community scientists across Wyoming - to gather observations of where, when, and how many monarchs and milkweed plants you find in the state. Through this, we hope to gain a better understanding of where monarchs migrate through Wyoming, at what time of year, and in what densities. We also hope to learn where and which species of milkweeds exist in Wyoming. With your help, we all can learn more about these wonderful organisms!
