Submit a milkweed or monarch observation

If you observe a monarch in a site that you don't monitor regularly, your observation can still help us understand monarch distribution and abundance. We need to know the date and location of your observation, and as much as you can tell us about the developmental stage of the monarch. You can also report other noteworthy observations. For example, you may have collected a queen larva at your site that was parasitized by a tachinid fly. For non-monarch observations, please be sure to record the details of the observation in the “Observation Details” box at the bottom of this form.

Please fill in as much of the following information as you can.
