All ant holes will spawn 1-6 Solen of a random type when approached, including giant beetles at times. For the more popular ant holes, the best way to locate them is to find the place where there are a dozen Solen and Players on a screen. Players usually gather to kill the massive spawn emerging from the ant holes.
