Is it really a monarch? Here are some tips to help you figure it out!

It’s time to send in the first Project Monarch Health samples of the season! 🦋📬

We've received our first fall roost reports from Iowa and Upper Michigan in recent days, as well as additional reports from Minnesota, where most of our roost observations have come from so far.

Monarch butterflies migrate alone during the day. They come down at night and gather in clusters, called roosts. Some roosts have only a handful of butterflies, while others will have hundreds or even thousands.

Roosts are a sure sign that some monarchs are migrating, but that doesn't mean all monarchs are on the move. Monarchs that emerge before about mid-August do not enter reproductive diapause as migrating monarchs do, and will continue to breed and lay eggs.

Whether you're seeing roosting monarchs or eggs and larvae, report your sightings to Journey North!

We had a blast at Colham Ferry Elementary’s STEM night! If you are in the Athens area, please consider us for your next STEM night or school event!

🌡️Higher temperatures may make monarch butterflies more vulnerable to parasites, according to new research from the University of Georgia. The study found that monarchs exposed to elevated temperatures were 22% less tolerant of infection.

🤒“What does tolerance of an infection mean? If you have the flu, it’s the difference between you being in the hospital or just having a stuffy nose,” said Sonia Altizer, lead author of the study and entomology department head in the UGA College of Agricultural and Environmental Sciences. Warmer temperatures cause toxic milkweed to lose its protective effect on monarchs, thereby increasing infection rates.

Published in Ecological Entomology, the study was led by Isabella Ragonese as part of her doctoral dissertation in the UGA Odum School of Ecology and Christopher Brandon as part of his undergraduate honors thesis.

Additional co-authors include Joselyne Chavez, Jacobus de Roode and UGA ecology associate professor Richard Hall.

Happy Earth Day! 🌎
Today is a reminder to care for it, everyday.

📣Calling all monarch butterfly enthusiasts— the GA DNR needs your help!📣

Monarch sightings during the winter can determine if the species can overwinter as non-breeding adults in the southern U.S. and how this might affect future population numbers.

Understanding migration and overwintering behavior is crucial to conserving monarchs, who are up for a spot on the Endangered Species list.

Thousands of monarch butterflies fly South each fall to overwinter in central Mexico— but not all monarchs.

If you spot a monarch in any stage (adult, egg, larval, and pupal) from November to March in the Southeast United States, please report it through Journey North or iNaturalist.🚨🦋

Want to track a monarch? 🦋

Well now you can thanks to ultra-light transmitters developed by Cellular Tracking Technologies!
This incredible new technology will help researchers better understand monarch migration and conservation. Monarch tracking isn’t just for researchers, either. You can download the Project Monarch Science app on your smartphone too! 📲📍
