erganzungsgruppe or erganzungstaffel

[srob48]

Hello, I am researching Luftwaffe aircraft and crew losses from 22nd June 1940to 22nd June 1941. I have got all the losses of Luftwaffe Losses from the microfilm copies at the Imperial War Museum in London, but it has come to my attention that not ALL losses are included in these records. In particular, not all losses from erganzungsgruppe or erganzungstaffel are mentioned. I know these are training groups or squadrons used before joining operational Units, but cannot understand why these losses are not included in the Luftwaffe Losses? Can anyone tell me a list of erganzungsgruppe and erganzungstaffel being used in 1940/1941, and where I can find out a list of all the losses suffered in aircraft and aircrew for this same period?
