Habitat: Wood and wetland occurring most frequently on land where cows are grazed. Can feed at pink flowers which have concealed nectar sources, making them unusable by other flies with less extended mouthparts.''Rhingia campestris'' is the main pollinator for many plant species and due to its long snout it can forage on tubulous flowers. Larvae are associated with cow dung. Adults males feed on nectar, while adult females feed on protein rich pollen, reflecting the cost of developing eggs.
