The Cephidae are slender, long bodied sawflies. They are characterised by elongate antennae with between sixteen and thirty segments. Cephidae produce only one generation per annum. Larval Cephidae feed inside the stems of grasses, roses or in some cases tree twigs. They are referred to as stem borers and their morphology is reduced in that they lack any abdominal legs and vestigial thoracic legs. The larvae cocoon within the plant stem. Cephidae that bore into grasses can be serious pests in cereal crops. Cephidae are predominantly a Eurasian family of about one hundred species falling within thirteen genera.
