Hi You need to be aware that you are editing the wrong articles There is an article for the Eastern cicada killer which already has the links to Coelho s and Holliday s pages that you have been trying to insert properly placed in the external links section at the bottom links do not go at the top of articles Please do not edit the Cicada killer wasp article which is a redirect or the Sphecius article it redirects to There is more than one species in this genus not just the one species that you are familiar with If you have citations regarding that species which are not already included in Wikipedia then that would be fine but as noted the information you ve been trying to add is already there and already in the correct place Thanks
