Banaszak & Rasmont (1994) list Fumaria (Fumariaceae) as a forage species. Friese states that the species can be found on various Asteraceae in the Balearic Islands.
Risch (pers. comm.) suggests that the species may have a preference for various Asteraceae.
Vereecken, Risch & Cortis (2007) show that the medium-flowered and early flowering Ophrys scolopax (Orchidaceae) in southern France is pollinated by patrolling males of Eucera (Hetereucera) elongatula which pseudocopulate with the labellum of the flower.
Both the males and the females have been observed foraging on inflorescences of Muscari neglectum (Liliaceae) and Salvia sp. (Lamiaceae). The females of this species have also been observed foraging on Rosmarinus officinalis (Lamiaceae) at the Massif de la Clape (departement Aude, France: Gruissan, 18.III.2007, 2m and 2f, leg. NJ Vereecken), close to the locality where it was first recorded from France.
