It will appear one more time for each boss of the world that you are. So World 1 has 5 times gecko appearances and each other world has 4. You got to be very careful around them, normally you can preemptive their position due to the chiming bells sounds that they make when you are close to them.
To avoid scaring them off, you should wear Thief's Ring and approach them slowly, don't try to shoot them with your Bow until you have the Lava Bow, because they will get up fast and run, dissapearing in the process.
