How do you get volbeat in emerald?
Although they are rare, they can be found on the route near the day care center. That's were I got mine.
it take times so you need to be patient and it can be found between verdanturf town and mauville city
You can find voltbeat at route 117. I would use the grass next to the flowers since they show up there. You can find Volbeat near route 117, but it is REALLY HARD TO FIND! i caught him after going into the grass about 20 times i thought it would be alot harder to find him you have to have an illumise in your party
