The less you mess with the female/ pair (even introducing bamboo), the more she will feel secure. I have had female klemmeri, sundbergi, kochi, madagascariensis, cepediana, etc. retreat for a day or 2 before laying. I have also seen these and other species bask out in the open, tuck away for a few hours to lay a clutch of eggs, and reappear. I just found two single-egg cepediana clutches today that I was not even planning on or looking for.
My opinion (based on working with Phelsuma, Varanus, and some other species) is that if females are frantically running around, something in the habitat is not right. Granted, this is my opinion. In other genera, females will hold onto their eggs and die if conditions are not appropriate. I have not observed this in Phelsuma. The key is to provide many options in or near the warm part of the enclosure: foliage, horizontal bamboo, slanted/ vertical sections with shallow hollows and deep hollows. The aforementioned cepediana clutches were not in a location I would have expected it to be, haha. They were in a bamboo hollow at about the midline of the Exo Terra.Basically, I try to observe them and have them teach me what they like. Then I try to mimic that.
I too have found laticauda to be both bold and secretive. I have some that like to hide and it appears to be part of their normal behavior.
I have not observed males hiding away. I did observe a female standingi go after a male standingi who got too interested in what she was doing when she was laying a clutch. I'll have to look for this more often. I think I just get too excited when the eggs are nearing deposition and I just think about them and ensuring the female recovers well.
Tape on the end of a long object works well, rolling out works.....fingers and tweezers never work. I painfully know that from saying to myself, "I know I shouldn't be doing this, but surely I won't mess this up. Surely, I'll be careful and won't pinch them too hard or drop them." Yeah, right. I have screwed that up every time!
