Hi Spillergent & welcome to WAB

There are day-time moths as well as night time moths. The one thing that does seperate butterflies from moths is that all butterflies have small knobs on the end of their antenna, moths antenna are usually thread like or feathery.
There are far more moths than butterflies & they are harder to identify ( I think so anyway!)
The Collins gem guides are a good pocket guide with basic info.
Enjoy your wildlife exploits
