A Vocuher speciman is needed to confirm difficult species. It is one killed & sent to an expert for identification. Many insects can be given species names by looking at the rude bits through a Microscope.
The same goes with fungi. By looking at the spores of a voucher speciman you can tell which species it is.
hope this helps.
