Lizard - Macro Photography

While sitting on a sofa outside waiting for a friend, two female lizards showed up to where I was. I wonder what they were up to and what they were looking for. I looked around but couldn't find anything tangible they could feast on.

It's rare for a lizard to come close to you except they found something edible they could feast on. The first one passed while observing me with causation, then, the second one followed.
