From calculations based on cell lengths and the locations of cells in nests it was estimated that failures in fertilization of eggs of the solitary bee Osmia rufa resulted in 6% more adult males in the population. After adjustment the sex ratio was almost exactly par. /// Aus Berechnungen aufgrund von Zellängen und der Lage der Brutzellen in Nestern der solitären Biene Osmia rufa wurde geschätzt, dass teilweises Misslingen der Befruchtung der Eier 6% mehr erwachsene Männchen in der Population ergab. Nach Berichtigung waren die Geschlechteranteile annähernd gleich.
