Larvae of this holarctic genus live and feed inside the fruits of Rosaceae. Species that attack 

 cultivated crops such as cherries, pears, and apples may be serious pests. Adults emerge in the 

 spring when their host plant is in bloom and the females oviposit in the ovaries. Sometimes 

 adults can be collected in large numbers from their host blossoms. The larvae feed in the 

 developing fruit of the host, the fruit usually falling off when the larvae mature. The larvae 

 enter the ground where they overwinter. All species are single brooded.
