Mary Foley Benson

She specialized in detailed, realistic watercolor paintings of plants and insects.

She was born in Storm Lake, Iowa, as Mary Carilla Foley. According to 1910 census, she had two brothers and two sisters. In 1922 she moved to Washington, D.C. to live with her family friends, John Merton Aldrich and Delia (Della) Ann Aldrich, and attend college. Developing interest in scientific illustration, she took a course in entomology with Dr. Aldrich, who at the time was the associate curator of insects at the United States National Museum. Possibly thanks to him, Foley soon got her first job at the United States Department of Agriculture (USDA). At the National School of Fine and Applied Arts and Corcoran School of Art she studied under artists Felix Mahoney and Harry Bradford respectively, and graduated in 1927. In 1928, she married Russell Bernard Benson, a patent lawyer and engineer at the US Patent Office, and their son John Raymond Benson was born in 1931. The couple lived in the D.C. area, and build their house the same year at Riggs Road, Langley Park, in Maryland. Mary Foley Benson worked as the senior scientific illustrator for the USDA's Bureau of Entomology and Plant Quarantine and the National Museum of Natural History, Smithsonian Institution. She collaborated with and illustrated for entomologists such as Lee L. Buchanan, Harrison Gray Dyar Jr., Carl Heinrich, Donald De Leon, Ashley Buell Gurney, R. A. Cushman, August Busck, Harry Gardner Barber, Louise M. Russell, Alan Stone, E. G. Davis, and George Paul Engelhardt. The majority of these illustrations were technical, black and white drawings of insects such as wasps, moths, true bugs, crickets, flies, weevils, roaches, and scale insects. During her free time, in the late 1920s and during the 1930s she participated in theater and music shows, notably the Pierce Hall Players. Thanks to her younger brother Charles L. Foley who was in the aviation business, she became interested in flying, and started taking piloting classes at College Park airport in 1936. Already in 1937, she had her first flight and was second at the annual Langley Day air meet, as part of Washington Air Derby. At that time, she was the only (and possibly the first) women trustee of the Washington Aero Club.

Already a licensed pilot, when the WWII started Mary Foley Benson joined the Civil Air Patrol and began ferrying airplanes for the War Training Service, joining her brother at Roosevelt Field. This led to her 1943 enlistment in the U.S. Army Air Corps (Women’s Army Corps) and the famous Ninety-Nines: International Organization of Women Pilots, the latter founded by Amelia Earhart in 1929. She flew Taylor J-2 Cub, Piper J-4 Cub Coupe, and Fairchild 24 aircraft, serving as the "on-ground Link Celestial Navigation Trainer." Unfortunately, women pilots were not allowed to teach in the air at the time. According to her biography in a 1946 exhibition catalog, "so far as is known [she] is the only women with an Army M.O.S. [Military Occupational Specialty] as pilot." With the end of the war, she divorced and moved to Los Angeles area to be with her parents. "She overstayed her time limit [at the USDA] and lost her job," and reinvented herself as a commercial artist, painting plants and clowns. Between 1948 and 1951, she attended the Otis Art Institute and studied under artist Norman Rockwell.

In 1964, she moved to Davis, California, thanks to a job offer from professor Howard Lester McKenzie from the Department of Entomology at University of California, Davis (UC Davis). This occurred only one year after UC Davis' department became independent from UC Berkeley, under Richard M. Bohart as chair. McKenzie and Foley Benson collaborated on the well-known publication Mealybugs of California with Taxonomy, Biology and Control of North American Species (Homoptera: Coccoidea: Pseudococcidae) which came out in 1967. These watercolor illustrations feature mealybugs on their host plants and surrounding habitats, together with plant damage, identified by specific locations of collecting, dates, collectors, and species. Other illustrators who contributed to this publication, aside from Foley Benson and McKenzie himself, were Helen C. Court, Julia Z. Iltis, and Douglass R. Miller. • Illustration — Harlequin bug by Mary F. Benson From mid 1960s until her retirement in 1972, she worked with professor William Harry Lange, Jr., another UC Davis entomologist, on an unpublished research on various agricultural pests. Just like in the case of Mealybugs of California and an earlier publication Insects: The Yearbook of Agriculture 1952, Foley Benson juxtaposed images of insect lifecycle with their host plants and habitat. She reused a magnifying glass visual tool from Mealybugs of California to emphasize the insect specimens, some of which are only a few millimeters long. These illustrations feature a variety of agricultural crop pests such as moths, worms, maggots, flies, aphids, weevils, and plant bugs, other pests such as snails and slugs, and insect predators which feed on pests such as lacewings, sawflies and lady beetles. The Lange series were consequently donated to the Bohart Museum of Entomology by Ellen Lange, while the McKenzie collection is shared between the Bohart Museum, Department of Entomology and Shields library at UC Davis. From her retirement in 1972 until her death in 1992, Mary Foley Benson was active in the Davis community, teaching painting and being an active Christian Scientist. She was the director of the Travis chapter of the Air Force Association, member of Ronald Reagan's Task Force, the Guild of Natural Science Illustrators, and head of the board of directors of the Davis Republican Women's Club. Her late work predominantly features botanical illustration of California's wildflowers made in watercolor and lithography. One example is the Golden Lupine, the official flower of the city of Davis, often combined with California poppy (state flower) and California dogface butterfly (state insect). This work was featured in Smithsonian Institution's exhibition called "Paintings of California Flora" in 1983 where she exhibited 45 artworks. She died in Davis in 1992, one year after a retrospective exhibition at her home studio. According to her will, some 60 artworks were bequeathed to the Hunt Institute for Botanical Documentation in Pittsburgh, Pennsylvania. In 2022, Miller and Stocks published an article where they identified 11 new felt scale insects (Eriococcidae), including one species named in honor of the artist, Ovaticoccus maryfoleybensonae.
