Hello Robert,
Maybe more information can be found on '
Biplane fighter aces - Belgium'
Via this site,
Aeropedia / Belgae Gallorum Fortissimi, I couln't find any reference to Belgian Air force actions in june 1940 - but maybe it will give the information in the future.
Just as this page: Belgian Air Force Losses May 1940 - as I didn't find yet any Belgian Air Forces casualties in June 1940 the information there stops in May.
Regards,
Bart
