Bug Catching was first introduced in The Sims 2: Seasons, allowing Sims to catch butterflies and fireflies. The Sims 2: FreeTime allows Sims to catch bugs and add them to a collection. In The Sims Castaway Stories and the DS version, it is possible to gather bugs, which can be eaten, traded, or kept and collected. The Sims 3 also features collecting butterflies and beetles. The Sims 3: Into the Future features robotic bugs called nanites.
