Brett has been the "Bug Guy" since his tenure at the Academy of Natural Sciences of Drexel University. He is a specialist in aquatic ecology (>30 years) and the founder of River Continuum Concepts, Inc. He has worked with species of conservation concern, including both terrestrial and aquatic invertebrates. His specialty is developing project specific monitoring criteria for aquatic and terrestrial ecosystems. Brett's favorite bug is Yoraperla because he worked with thousands of peltoperlids during his master's thesis and he still has a soft spot for this cute little bug. Additionally, they are usually abundant in beautiful, small undisturbed mountain streams.

Yoraperla, a genus of roach-like stoneflies from the family Peltoperlidae.
