It has almost no preferences towards soil type, but usually more abundant in moist soils. According to the Bouche's ecological characterization Ap. rosea belongs to the endogeic group, living and feeding in the mineral soil layer. Ap. rosea native in the Palearctis but widely introduced extratropically by men. Its present range comprises Europe, North America, South America, Africa, Asia, and Australia. It's different partenogenetic morphs are frequently described as separate species.
