Welcome! Beetles are fun and easy to care for, as long as everything is set up correctly. Beetles are good for children, because they are safe to handle and fun to watch, plus they are hard to hurt. Strategus antaeus is pretty easy to find, but I believe they (like many other rhino beetles) die in the winter. I Think Dynastes Tityus lives in florida, which is one of the biggest U.S native species, along with it's cousin Dynastes Granti. For collecting you can set up a blacklight aimed at a hanging sheet, or you can check bright lights near forested areas. I caught Dynastes Granti in Arizona at Gas Stations. A good book to read about U.S. natives is The complete Guide to Rearing the Eastern Hercules Beetle By Orin McMonigle. This book talks about Dynastes Tityus (most of the book is about this beetle), Dynastes Granti, U.S. Megasoma species, Strategus aloeus and anteus, plus others. Hopefully beetles can one day become as popular as pets in the U.S. as they are in japan right now. You can even buy beetles in vending machines in japan. Happy beetle Keeping!
