Dvobarvna dišavka (znanstveno ime Osmia bicolor) je vrsta samotarskih divjih čebel, ki je razširjena v Evropi in zahodni Aziji.

Samice dosežejo telesno dolžino do 12 mm. Glava in oprsje sta črne barve, zadek pa je poraščen z živo rdečkastimi dlačicami. Pri samcih je rdečkasta barva zadka manj kričeča.[2] Spomladi so ene prvih čebel, ki se pojavijo v naravi, saj lahko letajo že februarja.[3] Prvi se pojavijo samci, ki jim po nekaj tednih sledijo samice. Kmalu zatem se čebele parijo,[4] po parjenju pa začnejo pripravljati gnezda za nov zarod. Gnezdo si ta vrsta naredi v praznih polžjih hišicah.[5] Stene celic izdela iz zgrizenega listja, nato pa vhod zakrije z borovimi iglicami ali podobnim rastlinskim materialom. V Sloveniji je dvobarvna dišavka dejavna od marca do junija v eni generaciji.[6]
