Butterfly sightings are being tracked by scientists who need help from the public. A decline in population has prompted efforts to gather more information about western monarchs. People can contribute by taking photos of the butterflies or their caterpillars and sharing them through a special app.

The data collected will be used to understand the habits of western monarchs throughout the year. This information will also be used for an annual count of the species.

Further details about the project and how to participate are available, including how the collected information will be used to help the species.
