Submit a Milkweed or Monarch Observation

English | EspaƱol

This section is for monarch observations that are not made at regular MLMP monitoring sites or for relevant non-monarch observations. If you are a regular MLMP volunteer who observed a monarch in a site that you don't monitor regularly or if you aren't a regular monitor, your observations 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.

If you are entering an observation of a monarch you collected as an egg, larva, or pupa, and reared inside until it died, became an adult monarch, or produced parasitoids, please login as a “regular” volunteer.

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. If you have questions, please contact Karen Oberhauser. To see the list of submitted anecdotal observations, click here.
