Hey guys! I have no idea if this little idea was posted but I thought of something that gives me 100% catch rate for all beetles, even those Golden stags that I could never catch before doing this. I think this will be very helpful for new people, or people who are horrible at catching beetles, like me! 
I provided pictures with steps! I'm doing this on the island btw
Step 1: Find a seashell, or it could be any object really...I just like that the shell is small...and with it in your inventory, you are going to walk up to a palm tree until you are able to finally hit the tree with your net, but you are at the farthest distance that you're able to (cause if you're too close, you're gonna scare the beetle).
Once you found the spot, place the shell on that area
Step 2: Now that shell is your marker for when you are close enough to catch that beetle and release A and get it!
When you spot a beetle, you will walk up to it until you get a bubble showing the item's name, that is when you know you can catch the beetle.
And the shell will always stay at the spot you put it, even if you leave and come back!
I hope this was a helpful hint for some!
