Remarks
"Species of this Holarctic genus feed on herbaceous plants. On maturing, larvae bore into soft substances to form a pupal cell. This secondary host may be apples, other fruits, soft wood, or pith of other plants. Such records as hosts for species of this genus do not constitute the true host on which the larvae feed." (2)
