Superfaitiily CEPHOIDEA 

 Family CEPHIDAE 



The Cephidae are called stem sawflies because of the habit of the larvae which bore and feed 

 in grass stems, berry canes, or stems or twigs of various shrubs or trees. Those species whose 

 hosts are cultivated grains may be serious pests. The adults are slender, cylindrical, ichneu- 

 mon-like insects and may be found around the host plant. Adults of Cephini are commonly at- 

 tracted to yellow flowers in the vicinity of the host. About 13 genera and 100 species are recog- 

 nized for the world, most of which are Palaearctic.
