Signs of egglaying, what do I look for?

[Gamblingferret]

I have a male and a female long tail lizards, both are full grown and i was wondering what to look for if the female produced eggs? the bottom is jungle mix so its like finely shreaded mulch. I got my female a few weeks after the male, after they got aquanted my male started burrowing himself and whenever i come home from school the 2 lizards are usually burried in the same spot, is that breeding behavior??? any help will be appreciated.
