Hast Du die beiden Puparien, die Du sandtest, aus dem Blatt herausgeholt oder verpuppte sich die Larve auBerhalb? Ph. , zu der ich mimica urspriinglich als Unterart stellte, verwandelt sich im Gegensatz zu mimica m. ebenfalls auBerhalb des Blattes. Gib mir doch bitte im nachsten Briefe dariiber Bescheid. Bei meiner Ph. trollii ist die Fliege, und das macht mich bedenklich, aus Juni-Larven erst nach der Uberwinterung im folgenden] ahre erschienen.
