Do moonlights cause a delay in snails coming out at night?

Just curious if they want total darkness before they come out to clean.

Based on my asterinas and stomatella I'd say yes.
I have a long slow ramp an both ends. Lights go down they come out. In the am it comes up the go to bed.

Oddly SOME do stay out with light on
