Hey @youngminds, I apologize that you came across an old link. We’ve made numerous updates to our platform since 2015, so it’s not surprising that many links are no longer valid.
Nevertheless, all the features from that time are still available, and we’ve added even more for similar purposes.
For the flight charts, I recommend visiting our Explore Page. Beneath the grey and green stats bar, click on “Species profiles.” This will open a new window with all the species in our database. Simply search for the species you’re interested in, and it will display an information page with details, including its flight chart. For example, here’s the Monarch: Species Profile - Monarch (e-butterfly.org)
Additionally, you can use our experimental flight periods app, which we shared in this forum post: What is flying around? - Science - eButterfly Forum (e-butterfly.org) You can find it here: [link to the app]. If you need any tips on how to use it, please let me know, and I’ll be happy to guide you through it.
