International Monarch Monitoring Blitz

July 28, 2023 - August 6, 2023

Flier for the event. See event description for details.

Save the date for this year’s Monarch Monitoring Blitz from 28 July to 6 August 2023!

The International Monarch Monitoring Blitz invites community scientists from across North America to come together with the shared goal of helping to protect and conserve the beloved and emblematic monarch butterfly. Data collected by volunteers each year support trinational efforts to better understand the monarch butterfly’s breeding productivity, range, and timing in North America.

Consider promoting the effort within your networks. This is an opportunity to encourage, host or assist with monarch-related outreach events that involve submitting photo observations of monarchs (all life stages) and milkweed. There are promotional materials available in three languages – English, Spanish and French.
