The Third Trinational Monarch Monitoring Blitz Was a Success Thanks to You

Tuesday, September 3, 2019 3:58 pm

The Commission for Environmental Cooperation (CEC) is pleased to announce the results of the third annual Trinational Monarch Monitoring Blitz (the Blitz). For a week, hundreds of volunteers in Canada, Mexico and the United States helped monarch experts gain more information to enable better understanding of the distribution of the migratory monarch butterfly, an emblematic North American species. Between July 27 and August 4, 1,436 volunteers from the three countries participated in the Blitz, recording 32,883 monarchs at various stages of their life cycle, from eggs to full-fledged butterflies, and monitoring 59,176 milkweed plants—the sole food source for monarch caterpillars.

  • Monarch Lab is on YouTube!

    Monarch Lab Ph.D. candidate, Carl Stenoien, has been building an archive of stunning timelapse videos. Carl has been able to expertly record a variety of butterfly species pupating and eclosing. Some of Carl's videos even offer a view into the more sinister side of nature. Carl studies parasitoid wasps (small wasps that lay their eggs inside a pupal host), and was able to get some novel footage of Pteromalus cassotis parasitoids emerging from a parasitized chrysalis, as well as P. cassotis parasitizing a pupating monarch. These are some "must-see" videos for anyone interested in the amazing world of insects.

  • Rearing Monarchs Responsibly for Citizen Science

    Participating in the MLMP Monarch Survival Activity is easy, especially if you are already rearing monarchs. Simply collect monarchs from the wild, rear them indoors, and report whether they survive to adulthood, or, if they didn't, what caused their death. More information about the MLMP parasitism study can be found here. The data you submit is invaluable, and much of what we know about monarchs is due to the efforts of dedicated citizen scientists. Get involved today!

The MLMP Mission

Our mission is to better understand the distribution and abundance of breeding monarchs and to use that knowledge to inform and inspire monarch conservation.
