Bug Catching

A pastime for kids (ages 5–10) to do during the summer. It's kind of like fishing to see who catches the most and release at the end of the day. Bug-catching nets are a must.

Its mostly a boys' and Tomboy thing, although there are a few surprises. Extremely popular in Japan.

Video Games

 * Bug Catchers in Pokémon are explicitly based off this. The creator, Satoshi Tajiri, was even an avid Bug Catcher himself when he was a kid, and this pastime is actually what he based Pokemon off of.
 * You'll spend a lot of time doing this in the various incarnations of Animal Crossing.
 * The bug net in some of the Legend Of Zelda A Link To The Past is reminiscent of this (you can even catch bees and other insects with it as well as the fairies that return in later games). Later games even have bug collecting subquests (particularly The Legend of Zelda Twilight Princess, where there was a massive variety of bugs to collect and one of a kind gold versions of each you had to collect as part of a side quest).
 * In The Legend of Zelda Skyward Sword, bugs have to be caught and given to an NPC in order to improve Link's potions.
 * The player does this every once in a while in Monster Hunter as well.
 * In The Sims 2, Sims can catch bugs. They even get a collection box with pictures of the species they've caught. Sims can also catch bugs and put them on display in The Sims 3.

Western Animation

 * In SpongeBob SquarePants, SpongeBob and Patrick go jellyfishing all the time.

Real Life

 * The naturalist Gerard Durell's autobiography, My Family and Other Animals, details the author's childhood (and continuing) obsession with nature, and the many different species he collected as a child.
 * During the Boer War, one of Robert Baden-Powell's favourite cover stories when he was spying was as a butterfly collector. Not only did this seem so innocent to the Boers seeing this grown man chasing butterflies that they didn't realize that he only seemed to find ones around their fortifications interesting, but he could disguise his maps in the pictures of the ones he caught.
