The recently increased importance of sunflowers (Helianthus annuus Linnaeus) as a crop has brought with it an increased interest in the sunflower maggot, a long-recognized common name for Strauzia longipennis (Wiedemann). The larva of this species bores downward in the stem and feeds upon the pith of sunflowers. Until recently the genus Strauzia was considered to include only the type-species S. longipennis, with 7 varieties (Foote, 1965). It is now known that some of these varieties should be classed as distinct species, differing morphologically and biologically.
