An oligolectic species, specialising in Asteraceae pollen (Scheuchl, in prep.) .
Roberts & deMeulemeester (2014), citing others, states that the species is presumed to be oligolectic, specialising in collecting pollen from Asteraceae species, in common with other members of the sub-genus Chlorandrena. S. Roberts (pers. obs. 2018) found the soecies in abundance at flowers of Sonchus tenerrimus (Asteraceae) in Malta.
Flower visitation has been observed at Sonchus tenerrimus (Asteraceae) (Warncke 1976), Calendula arvensis and Hyoseris radiata in Corsica (Ferton 1901), Crepis clausonis (Saunders 1909), Taraxacum laevigatum (Alfken 1914) and Senecio nebrodensis (Benarfa et al. 2014) in Algeria, Sonchus tenerrimus in Mallorca (Warncke 1976) and Hirschfeldia incana (Brassicaceae); Ononis natrix (Fabaceae); Cistus albidus (Cistaceae); Chrysanthemum coronarium and Sonchus tenerrimus (Asteraceae) in Ibiza (Hohman 1984).

The males are pollinators of Ophrys lutea s.lat. (Orchidaceae) in southern Italy, Algeria and Kefalonia (Greece) (Paulus and Salkowski 2007), and also of Ophrys fusca ssp. fusca in Spain (Vázquez Pardo 2009).
