Bug collecting

Bug Catching was first introduced in The Sims 2: Seasons, allowing Sims to catch butterflies and fireflies. The Sims 2: FreeTime allows the catching of bugs and adding them to a collection. The Sims 2 Castaway for DS, allows the player to gather bugs, to either eat, trade and keep and collect. The Sims 3 also features collecting butterflies and beetles.

Bug Catching
Butterflies appear during the day and fireflies in the evening. A Sim can try to catch a butterfly or firefly in a jar by clicking on the tile where they appear. It may take several tries before they catch one. Once one is caught Sims can view them inside the jar or release them. If they are left in the jar they will die.

With FreeTime, Sims who catch butterflies might occasionally put them in their bug collection.

Bug Hunting
There are three types of bugs a Sim can catch: Beetles, Butterflies and Spiders. To catch bugs, click on an area outside and select "Hunt Bugs". Sims will continue this action indefinitely but will not always catch anything. Once a Sim catches a bug it will be placed in their collection box, which can be found in their inventory. Players can view the collection by placing it on the lot and selecting "View". When Sims go hiking, they might catch a bug. If they already have that bug in the collection, they'll release it. A Sim must have at least level 8 enthusiasm in the Nature hobby to be able to collect all of the bugs.

If a Sim hunts bugs for very long, it will have a strong effect on his or her hygiene. Occasionally, a Sim who is hunting bugs will be chased by bees.

The Sims 3
Butterflies and beetles are also collectible in The Sims 3.
