The Ulidiidae or picture-winged flies are a large and diverse cosmopolitan family of flies (Diptera), and as in related families, most species are herbivorous or detritivorous. They are often known as picture-winged flies, along with members of other families in the superfamily Tephritoidea that have patterns of bands or spots on the wings. Some species share with the Tephritidae an unusual elongated posteroapical projection of the anal cell in the wing, but can be differentiated by the smoothly curving subcostal vein. Two species, Tetanops myopaeformis and Euxesta stigmatias, are agricultural pests.

Stephanomeria virgata, commonly called rod wirelettuce, twiggy wreath plant, and virgate wirelettuce, is a herbaceous annual plant of the sunflower family, Asteraceae. It can be found growing in Western North America, specifically California, but also in Oregon and Nevada and northern Mexico. This plant can be found in dry, open habitat types at elevations below 2100 meters. S. virgata is sometimes used as an ornamental plant.
Borsonella is a genus of sea snails, marine gastropod mollusks in the family Borsoniidae.
Stephanomeria diegensis is a species of flowering plant in the aster family known by the common name San Diego wirelettuce. It is native to the coastal hills and ranges of southern California and Baja California, where it grows in many types of open habitat. It evolved as a hybrid of Stephanomeria exigua and S. virgata. Furthermore, it is thought to be the result of homoploid hybrid speciation, which is uncommon. The plant is frequently misidentified as one of its parents, especially if older taxonomic keys are used. This is an erect annual herb easily exceeding two meters in height. Its slender stem has many spreading branches. The basal leaves are linear to lance-shaped and up to 10 centimeters long. The leaves wither early and are absent for most of the year, giving the plant a twiglike appearance. Leaves on the upper stem are small and reduced. The inflorescences are usually clusters of flower heads located at intervals on the stiff branches. Each head has a cylindrical base lined with phyllaries. These are often glandular. The head contains several ray florets, each with an elongated tube and a white or pink-tinged ligule measuring around a centimeter long. The fruit is a grooved achene tipped with a spreading cluster of long, plumelike pappus bristles.
