It sounds as if you aren't always home in the middle of the day to observe a successful egg laying. But a quick outline on what to expect, and then fit it to your ability and opportuntiy to observe. The entire egg laying process is usually a 4-8 hour event, consisting of the excavation of a hole 4-10 inches deep, depositing of the eggs, and then reburying the site. Often holes can be dug, shallow and otherwise, and no eggs laid, as for some reason the female found it unsuitable. In about 10% of the cases, a female will fill in an excavated hole without laying. If you are there to observe any part of this sequence, it is easy to go and excavate after the female is done. But if not, there are still telltale signs. Most noticably, the female will no longer have a belly full of small marbles, and if not sure, you can gently palpate her abdomen and feel for them. Secondly, any female engaged in serious excavation will have noticable amounts of dirt adhering to her head and limbs. If you see a dirty female, but no sign of a hole, then odds are the deed is done. I have heard of hobbyists spreading a thin layer of sand on the surface of their medium, or actually burying a thin layer of colored sand about 1 inch beneath the surface, to indicate the approximate location of the dig based on observable disturbance. The effectiveness of this technique will vary though, based primarily on the amount of area provided for egg laying, false digs, etc. It is not uncommon for females to return to a hole begun the day prior, so if she begins to dig, and then abandons the spot, I would leave it be. Some females will also often come and go from the same hole several times in a day. And some don't waste any time, and dig promptly, lay, and rebury with no second thoughts. A female may also drop a couple of eggs in the days prior to a successful laying, as well as retain a couple after a laying, which are usually expelled within a few days, so if this is observed, it is not necessarily cause for alarm. But, too many false digs may indicate an unsuitable temperature or moisture problem. Good luck, and I hope it goes well for you. Jim at The Chameleon Company
