When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "U-Sphere - Michael Vaillant",
   title = "Crop Circles et protohistoire humaine --- U-Sphere - Michael Vaillant{,} ",
   year = "2007",
   url = "\url{http://www.u-sphere.com/wiki//index.php?title=Crop_Circles_et_protohistoire_humaine&oldid=9993}",
   note = "[Online; accessed 18-février-2026]"
 }
