Cresselia help

So does Cresselia only appear during the day? Because I’ve been roaming for a couple days and all other roamers appeared within an hour of roaming. Since I’ve only played at the night the last few days I was wondering if it only appeared during the day

Did you already finish Diana’s quest where you deliver her parcel to Persephone yet?

Yes I did. That’s why I find it odd, I had already caught all roamers before that and completed the quest 3 days ago. Last few days I’ve only been able to play during the night,that’s why I was wondering if it was anything related with the time of the day

It’s quite a bit more rare, that’s all I think. I’ve found it in the night before iirc
