eli5: Why do worms get out on the asphalt when it’s raining?
In: 3592
One theory is that when it’s rainy it’s prime time for a worm to find a mate. Worms can only move on wet surfaces and it is easier for them to find a mate while on the surface because they move faster compared to being underground and they are more likely to bump into each other. This is supported by the fact that only some of the worm population will surface during the rain and the vast majority of them are adults.
So the worm on the asphalt in the rain could just be a horny worm looking for mate.

I am always trying to save the worms and put them back in the dirt because they end up all dried on the sidewalk. When we had a pool I’d have to dish so many worms out of the pool on rainy days trying to save them.
