The Legend of Zelda: Twilight Princess/Golden Bugs

Throughout the land of Hyrule, there are 24 Golden Bugs scattered around, that you can pick up by simply pressing.

If you give a Golden Bug to Agitha (in "Agitha's Castle" in Hyrule Castle Town), she will upgrade your wallet to a "Big Wallet" and she will also give you 50 rupees. From then on, she will give you 50 rupees every time you give her a Golden Bug, and if you make a pair of two like bugs, she will give you 100 rupees. When you have given her all the insects that can be found in the game, she will give you a "Giant Wallet", which holds 1,000 rupees. When you catch a bug, you can keep on catching it again and again, but you will only get a heart for the first one. When you have given a bug to Agitha, it will still be shown on your collection screen, and there will be a little butterfly symbol next to it. If you select a bug on the screen, it will give you a little bit of information about it. You can also visit Agitha's Castle whenever you want and use your lantern to draw bugs closer, if you like.

Tactics
If you're having trouble catching a Golden Bug, you may want to try the following tactics:
 * 1) Use your Gale Boomerang or Clawshot to pull the insect to you. If it flies away quickly, you may have to repeat this tactic.
 * 2) Stand still and use your Lantern to draw the bug closer, then when it is right near you, press  to grab it.
 * 3) Sit and wait. If you're having serious trouble catching an insect, just stand by it and don't move. Wait for it to come to you.
 * 4) If you're having trouble seeing an insect, wait for night to fall. The Golden Bugs tend to blend in with the light of the day, making it somewhat difficult to spot them.
