Monarch counts this Thanksgiving has hit another record low (source). We are currently looking for your help if you’ve seen a monarch, of any life stage (egg, caterpillar, chrysalis, butterfly), in the west.
The Western Monarch Mystery Challenge is a community science campaign running February 14th through April 22nd 2021, formed by researchers from Washington State University, Tufts University, UC Santa Cruz, and the Xerces Society to learn more about monarchs in order to inform urgent conservation efforts. Thank you all for participating and contributing to a meaningful and important project!
How to participate:
- If you see a monarch outside of overwintering groves, take a picture! (Don’t worry, it can be far away and blurry).
- Report it through the following options and be sure to include date and location:
- Be entered to win a variety of prizes every week you report a sighting
- To stay updated: follow us on Twitter, Facebook, and Instagram.
Have the Challenge Dates Passed?
You can still submit sightings! If you see a monarch of any life stage (egg, caterpillar, chrysalis, butterfly), take a picture! (don’t worry, it can be far away and blurry).
