YouTube:
Snake Discovery is a YouTube channel that provides good videos on jumping spiders. Some include how to find jumping spiders and how to mate them.
JumpingSpidersUSA is also a really good YouTube channel for spider related information. There’s 52 videos full of good facts and necessary information.
Reddit:
R/jumpingspiders has a community of 33.6k and if you ever have any questions at all you can ask them there! I have seen people respond to others helping them with identifying species, sex, age, and if the spider is gravid or not. You can also get responses to questions about other spider related things.
Books:
This book, “Jumping Spiders. Jumping Spider Pet Owners Guide” by Edward Dunbarn, helps with lots of information. It is the best jumping spider book for care taking information on the market! It is a book full of all the information you need for keeping jumping spiders.
