The Leon Cambre Collection of Long-horned Beetles (Cerambycidae)

by Terence L. Schiefer, uploaded on 1 October 2013

A major collection of over 10,300 specimens of long-horned beetles (family Cerambycidae), representing 564 species, was recently donated to the Mississippi Entomological Museum at Mississippi State University by forestry alumnus, Leon Cambre.  The collection, developed by Cambre over a period of 55 years, is especially strong in species from throughout the southeastern United States, but it also includes an excellent representation of the entire North American fauna.

Cambre developed his interest in long-horned beetles while a student at Mississippi State University where he took insect taxonomy courses from Dr. E. W. Stafford.  After receiving his degree in Forest Management in 1958, he began his long and distinguished career with the U. S. Forest Service.  In the early years of his career, Cambre worked as a Forester and Assistant District Ranger in Mississippi and then as a Forest Entomologist for eight southeastern states.  Later, he served as District Ranger for Ouachita National Forest in Arkansas, Deputy Forest Supervisor for Daniel Boone National Forest in Kentucky, Forest Supervisor for all six National Forests in Mississippi, and Forest Supervisor for Mark Twain National Forest in Missouri, collectively administering over 3.5 million acres for natural resource management during the course of his career.  He also worked in Washington D.C. under a Congressional Fellowship and then served as Director of Legislative Affairs and Director of Cooperative Forestry for the U. S. Forest Service.

Leon Cambre's career path necessitated frequent moves by his family, allowing them to experience living in many interesting places across the southeastern United States.  Living in or near National Forests provided a life full of adventure for Leon, his wife, Elizabeth, and their children.  The frequent moves and other job related travels gave Leon ample opportunity to collect long-horned beetles from a wide variety of locations in most of the southeastern states, which he did so avidly.  Many of his specimens were collected in light traps or on flowers.  Others were collected on or reared from host plants.  Collecting long-horned beetles was often a family affair, with Elizabeth and the children assisting in capturing the beetles.  Even Leon's mother collected long-horned beetles for him in a light trap at her home along the Pearl River near Jackson, Mississippi.

When Leon began his studies, species identification of long-horned beetles was much more difficult than it is today.  There was no comprehensive work covering the entire North American fauna, and accurate identification often required access to original descriptions scattered in publications that were difficult to obtain.  To facilitate his studies, Leon gathered much of the necessary literature and established communications with many of the taxonomists and collectors who were studying long-horned beetles at the time including John Chemsak, Josef Knull, Bill Tyson, Frank Hovore, Dick Penrose, Jim Cope, and many others.  In order to increase the diversity of species in his collection, Leon exchanged specimens with many of these individuals, obtaining species from western and northern North America for specimens from the southeastern United States.  Over the years, Leon has also contributed many specimens to various Forest Service regional research collections and to a number of university collections in the southeastern United States.

One of Leon's important contributions to the study of long-horned beetles was his discovery of a species new to science.  In 1959, while working in Bienville National Forest near Forest, Mississippi, Leon collected an unfamiliar long-horned beetle on the flowers of Black-eyed Susan.  In the following years, he collected additional specimens throughout Bienville National Forest and other nearby areas, always on the flowers of Black-eyed Susan.  The specimens did not fit the description of any known species of long-horned beetle, and Leon, suspecting that they were a species new to science, sent them to long-horned beetle taxonomists, Gorton Linsley and John Chemsak at the University of California.  They agreed that it was a new species and described it in their monograph on North American long-horned beetles, naming the species Strangalia cambrei in honor of its discoverer, Leon Cambre.  To date, the species is only known from Mississippi.
