The pieces of information listed above are needed to have a valid biological record. Even from just the information above a validator would be able to rule out certain species (outside its geographic distribution or flight period) or potentially flag a record to request more information.
For particular taxonomic groups the validator may request that other pieces of information are also mandatory. A photo of the species you are recording is extremely useful and something we encourage all our recorders to try and include. While it is not always possible to achieve this, a photo showing all of the species or a particular feature is very helpful. Do not worry if your photo is not amazing quality, just try to have it in focus, a record shot is exactly that, one to help confirm the identity of the species and validate the record.
