Not sure about size and maturity in this species but I hope it is not DKS! Some primates when little will engage in mock mating and have witnessed the drumming first hand with my Ecclesiasticus and ended up with the phantom egg sack. The Emeraldus never drummed that I know of . She webbed herself in and I thought she was going to molt! Checked her the next day, and boom , another phantom egg sack! BTW not good with the CM method of sizing but my Ecclesiasticus was around 4" DLS when did the drumming thing. Maybe a little less.
