Ross Taylor Bell (April 23, 1929 – November 9, 2019) was an American entomologist with particular interest in the invertebrate natural history of Vermont, United States, and carabid beetles.

Together with his wife, Joyce Rockenbach Bell, his work at the University of Vermont was largely taxonomic, where they described more than 75% of the rhysodine species known to science.

The following summer, he took a job with the taxonomic survey, though this turned out to provide him with little scope to develop his skills and interests.

Before he could take this up, though, he was called for national service, and spent two years at Fort Dietrich, Maryland, then known as America's 'Germ Warfare Centre'.

Spending a significant amount of time working with fleas, he discovered a rapid way to differentiate males from females.

In the following year, he married Joyce Elaine Rockenbach of Whitestone, Queens, New York City.

In the 1970s and 1980s, Ross and Joyce extended the boundaries for their entomological work beyond Vermont, stretching as far as New Zealand and Papua New Guinea.
