This Wildlife Wednesday, we interrupt our “spooky” October critter posts to bring you another October critter:the monarch butterfly (Danaus plexippus). 🦋
Right now, thousands or even millions of monarch butterflies are winging their way across Texas on their way to the mountains in Mexico, where they will spend the winter. These monarch butterflies were born in the northern United States or Canada, so they are flying along a route they have never been before – amazing!
Today we focus on two ways that people like you and I can use technology to help scientists track monarchs! Engaging regular folks like us (rather than scientists) is a great way to “crowdsource” information so scientists can gather more data. 📋 This is called Citizen Science.
One of our citizen science opportunities today involves identifying monarchs (with or without a photo), and one opportunity is more passive – it only requires you to have an app open! 📱
- Journey North:
Best viewed from your computer 💻 rather than on your phone -- click on this link and you can see a real-time map of where adult monarch butterflies have been sighted.
https://maps.journeynorth.org/map/?map=monarch-adult-fall&year=2026&season=fall
Make a free account and log in, and you can report your own sightings! There are other maps you can look at (and report on!), too, such as monarch fall roosts (when they gather to rest at night), and even maps of where other types of animals have been spotted.
- Project Monarch – We just found out about this due to an entomologist who recently came out to the park to do monarch research. Scientists carefully attach a tiny transmitter with solar panels, to a healthy adult Monarch butterfly. If you download the free Project Monarch app and click “Scan”, your phone acts as a receiver, and if a tagged Monarch flies within 100 meters, your phone can track its location, and you’ve contributed to scientists’ knowledge of where that monarch is at!
The monarch migration is a fantastic phenomenon, and Journey North and Project Monarch are great tools that can help these amazing insects! 🦋
