@Ungoliant none of the 4 lycos I have, have molted. I have 3 females. My Gladicosa Gulosa had a sack that went flat within a day and she ate it . The one that laid her sack last night was REALLY fat. The one this morning wasn't and if she wasn't doing a little dance over her water like the other one , I wouldn't have thought she was gravid. But I am still very new to this.
