Go to a Nook Mile island, pull every plant and cut down every tree except the palm trees. Break all the rocks. This forces the bugs to only spawn on the palm trees and ground. Keep scaring them away (or catch them if you want) until you get the bug you're looking for.I have been spending like 2 hours a night trying to find one lol! And I just caught my first one right after I posted this!
Yep that’s what I have been doing but only got lucky tonight!Go to a Nook Mile island, pull every plant and cut down every tree except the palm trees. Break all the rocks.

I was tired of not finding a scarab beetle on my island, so I did the above and had one within a half hour.
