Darwin truly appreciated worms and wrote a little known book about them. worms are indeed a very important part of the ecosystem, recycling matter and aerating soil. worms come out of their burrows during daytime to mate, even though this makes them very vulnerable to predators. i've seen a youtube video (in fast motion) which shows that they come out in their multitudes and drag fallen leaves into their burrows. most fascinating. they are generally not given due credit for the amount of (unseen) work they do. improving soil structure in the garden lessens the amount of worms crawling out onto concrete during rain. i don’t subscribe to the mating idea, as i’ve seen even baby size worms come out after heavy rain. they look more like they’re trying to escape the deluge. if this is because of carbonic acid, as some suggest, concrete is an alkaline environment that would neutralize the carbonic acid. so much so that soon after rain finishes a lot of worms don’t make it back and dry out on the alkaline concrete. on especially heavy rain events, worms will even climb up doors and brick walls.
