There’s a hidden world of eight-legged wonders that Fullerton College Professor Emeritus Lenny Vincent has dedicated his life to uncovering. With a master’s degree in entomology from University of California, Davis and a Ph.D. from University of California, Berkeley, Vincent’s fascination with arachnids led him to develop a unique course on the biology of insects and spiders at Fullerton College, where he taught from 1987 through 2015.

“It was my interest and the community’s interest in spiders, and I wanted to get students involved,” said Vincent.


For much of his career, he was invited to speak about spiders to various environmental groups, which finally inspired him to share his knowledge with a broader audience. His interest in arachnids led him to his passion project, the Spider Identification Guide for Orange County (OCspiderguide.com). The online guide is free, funded through the Schlinger and Fullerton College Foundations, and designed with the user in mind – easy to navigate and understand even for those with no scientific background.

Vincent continues to be fascinated with new discoveries. One of his most memorable experiences came from the field with the thrill of discovering a species previously unrecorded in Orange County, the brown widow spider. The discovery shifted the conversation among local entomology enthusiasts and led to a published paper in referred journals by Vincent and five of his students.

The online guide, still a work in progress, reflects Vincent’s ongoing commitment to expanding our understanding of the local spider population, which boasts over 300 species. Vincent hopes the guide will serve the residents of Orange County and inspire students at Fullerton College. As an ongoing educational endeavor, he balances science with accessibility, emphasizing visual identification and minimizing scientific jargon.

Vincent’s guide will continue to evolve, with plans to make it available in print for broader distribution. Through partnerships with environmental groups and educational institutions, Vincent hopes the guide will become a staple resource, promoting appreciation and understanding of local spider biodiversity.

His lifelong work reminds us of the web of life that exists just outside our doors, ready to be explored.
