Sueo was born on September 21, 1933, in Olaa, Hawaii.  He was the 8 ^th child of Kunichi Nakahara and Tamiyo Yasumura.

Sueo attended Olaa Elementary from 1939 to 1948, and he was a member of Hilo High School's Class of 1951.  He attended the University of Hawaii in Honolulu and graduated in 1955 with a BS degree in General Agriculture and a minor in Biology.  He was in Army ROTC during college. After graduation he fulfilled his active-duty obligation and was stationed in Incheon, Korea from 1955 to 1957.  By the time he was honorably discharged from the Army, Sueo had attained the rank of 1 ^st Lieutenant.

When he came home from Korea in 1957, Sueo was looking for work.  One of his favorite professors mailed him a clipping from the college newspaper announcing "Agricultural Jobs for Seniors."  Sueo applied to the US Department of Agriculture, and by October 1957, he was off to New York City to begin his training as an inspector.  After completing his training in May 1958, Sueo's first job was as a Customs Inspector for the Plant Quarantine Division in Miami.  Sueo loved the three years he lived in Miami.  He enjoyed the work, and he spent his free time fishing and exploring the area. During this time, he had discovered a shipment of marijuana in a routine port customs inspection, and he enjoyed some excitement as a federal witness in the criminal drug trial in NYC.

Sueo's next post was Seattle, WA, where he worked as an inspector and now also as an insect identifier in Entomology.  Sueo would spend the next decade or so in Seattle, another city that he loved.

After Seattle, Sueo found a position as a research entomologist with the USDA in Washington, DC and later at the USDA research station in Beltsville, MD.  Timed with the relocation to Beltsville, Sueo moved to the town of Laurel, MD and into his home of 42 years.  Sueo became known and respected for his expertise as an identifier.  He named three insects previously unidentified, and he was considered an expert on Thrips.  In addition to his lab research, Sueo also travelled to present his work at conferences and to consult.  The work trips opened the door to his next love:  travel.  Sueo travelled all over the US and Canada as well as Europe, North Africa, Asia, and Australia.

Sueo loved his home in Laurel, too.  He was an avid vegetable and flower gardener and was awarded the town's "Golden Shovel" award for Best Yard.  He enjoyed hosting visiting entomologists and taking them sightseeing in DC and Baltimore.  And he loved his neighborhood bar, Oliver's.  Most nights of the week, you would find Sueo here, enjoying a couple of beers, maybe dinner, good company, and the bar trivia game.

Even after Sueo retired in 1998, he continued going into his lab, researching, writing, and travelling up until about 2011.  And up until the last couple of years, Sueo kept up his gardening and regular visits to Oliver's.

Sueo is survived by his sister Fumie Sayegusa, brothers Shigeru Nakahara and Jitsuo Nakahara and a handful equally well-loved nieces and nephews.
