There is some guidance on the Providing moth records page. The Excel template available for download is a large file because it contains a Lepidoptera checklist to make sure names match those needed for import, but any Excel file which provides the records with the information needed is ok. Generally speaking, providing records once or twice a year is good. The preference if for records for each date, with numbers if available - these data all help producing phenology charts etc. However whatever you can provide is good.
