Roost Activity
The leading edge of fall roosts recently were concentrated around latitudes 35-38°N, primarily in Oklahoma and Kansas. Roosts show us where large concentrations of migrating monarchs are found and reveal the main migration pathways to Mexico. Check out the Monarch Fall Roost map to explore more observations.
Journey North is excited to partner with the North Carolina Wildlife Federation (NCWF) to promote monitoring monarch and hummingbird migration along the Butterfly Highway.
Bruce E. Young, Chief Zoologist and Interim Chief Scientist with NatureServe, shares how data from participatory science projects, like Journey North, have contributed to their work in managing federal lands.

Monarchs are on their way with higher than anticipated numbers flying this Fall! Large numbers of monarch larvae are still being found in fields of northern Utah – a harbinger of more adult monarchs to come.
Roosting Activity
A roost may have a handful of butterflies or more than you can count. Fall roost reports should reflect the number of monarchs observed within a roost for a single night. Please report every evening when roosting monarchs are present.
