International Monarch Monitoring Blitz: 28 July to 6 August 2023

June 12, 2023 by Team Journey North

Every year, thousands of individuals from across Canada, Mexico, and the United States join efforts to support monarch butterfly conservation by collecting observations of monarch butterflies and milkweed plants. Join this vital trinational initiative by sharing your monarch and milkweed sightings from 28 July to 6 August 2023 with Journey North. Read on to learn more.

Mark your calendars for the 7th International Monarch Monitoring Blitz!

During this 10-day period, from July 28August 6, the #MonarchBlitz invites people across North America to look for monarchs and milkweed plants and examine them for monarch eggs, caterpillars, and chrysalises. Blitz data are uploaded and shared with researchers via the Trinational Monarch Knowledge Network, a central repository that, in combining data from various sources, assists researchers in performing large-scale temporal and spatial analyses. The data collected by volunteers help researchers answer key questions about monarch butterfly and milkweed distribution, timing of reproduction, and the use of natural resources. In turn, this information helps conservationists identify and prioritize actions to conserve the species.

To take part in the Blitz, share your observations with Journey North!

In addition to reporting to Journey North during the Blitz, follow along and share your participation in this international conservation effort on social media by using the hashtag #MonarchBlitz
