These flies are generally distributed, and appear during the 

 spring and the summer in gardens and woods, or on sandy heaths 

 and plains ; their flight is rapid, flitting, and humming, and they 

 suck the nectar of flowers while hovering on the wing. The 

 larvae are supposed to live on the roots of plants.
