These wall lizards are taking up where they left off last year (or maybe last month, or week or day or hour). Eventually from 3 to 7 eggs will be deposited in a hidden somewhere (a flower pot? under a rock) and left to hatch. Anyway, it doesn’t take too long for them to “do what they gotta do” before scampering off in search of a post-conjugal bug or two. Good luck to them.
