Barbara Bartell is a Colorado native. She graduated from Arvada High School in 1963 and attended Colorado State University from 1963 to 1965. Butterflies have always fascinated her. As a child living in Evergreen, Colorado, she collected butterflies and began collecting and studying them again in 1968. As a faculty associate with Colorado State University, she does volunteer work with their butterfly collection. Since 2004 she has volunteered in the butterfly collection of the Denver Museum of Nature & Science where she essentially organized the entire collection. She became Department Associate in 2009.

David Steinmann is a biospeleologist, or cave biologist, who researches cave life in search of new species. David received a B.A. in Physics and Biology from the University of Colorado at Boulder in 1990 and is a volunteer firefighter in Boulder County. David studies caves throughout Colorado, which has the highest elevation and coldest caves in the continental United States. He began volunteering with the Zoology Department in 2002 and became an Associate in 2009. His research requires climbing, crawling, squeezing, and rappelling into total darkness, where he looks for cave-adapted life forms that are often eyeless and albino. So far, David has discovered over 100 new species and several new genera, with three new species named after him. Colorado's cave invertebrates are being studied to find new and rare species, provide insight into cave fauna evolution and biodiversity, and to help protect cave life.
David also works as a wetlands biologist and rare plant specialist. He has managed over 500 wetland delineation and environmental assessment projects, including local government work, United States Forest Service contracts, ski area expansions, recreational trails, hospital complexes, highways, and public schools. Several new plant species were recently identified while he was out exploring for caves. He is an active member of the National Speleogical Society, Society of Wetland Scientists, and Trout Unlimited. David is often found underground searching for new species, with his caving headlamp providing the illumination. He became a Department Associate in 2009 and a Research Associate in April 2012.

Ken van der Laan
Dr. van der Laan is documenting the distribution of dung beetle species in Colorado life zones. He has been setting up and collecting from dung beetle traps and fecal droppings along Bear Creek, Jefferson County, Red Rocks Denver Mountain Park next to the I-70 bison enclosure, above and below timberline on Mt. Evans, and at the Prairie Conservation Center in Aurora.
He has found that there are dung beetles that are specific to particular life zones, while other species are more general in distribution. Dung beetle species evidence seasonality in their presence. The predominant species in all zones are native, however, there is a puzzling pattern in the presence of introduced European species. "Non-dung" beetles have also been collected adjacent to and in the traps. Those species distributions through space and time are also being analyzed.
Dr. van der Laan has been a native of Colorado since 1939. The trapping system is labor intensive and requires lots of bending over. Thus, the aid of able bodied volunteers has and will be most welcome. Ken occasionally springs for lunch for "his" volunteers.
Ken went to South High School and University of Denver (1961). He completed his doctorate in zoology at the University of California-Berkeley (1971). His publications – now ancient – concern a terrestrial snail species from coastal California and the environmental impact on invertebrates in an Illinois riparian ecosystem. He did extensive work on southern and central California coast hermit crabs and used to know the names of every West Coast gastropod worthy of becoming shelter for the crabs. Yes, even the itty bitty ones.
Dr. van der Laan retired as an educator after 35+ years, teaching every age level except elementary school. He taught biology, invertebrate zoology, animal ecology, marine biology, biostatistics, and human anatomy and physiology. He most recently taught at Golden High School. Ken became Research Associate in 2011.

Michael J. Weissmann
Michael J. Weissmann, Ph.D., is a co-founder and former curator of the Butterfly Pavilion and Insect Center in Westminster, Colorado. He has consulted with a variety of similar facilities since then. He was the initial Executive Director of the International Association of Butterfly Exhibitors and Suppliers, a butterfly house industry 501(c)(6) trade association, and currently serves on several IABES committees. Working with former Kallima Consultants partner, Richard Cowan, they created London Pupae Supplies of Los Angeles (now LPS LLC), which has become the largest importer of live tropical butterfly pupae in North America, now operated exclusively by Mr. Cowan. Scientifically, Dr. Weissmann has published a variety of technical articles about insect taxonomy, biology, and behavior, and has co-authored popular guides to insects of regional parks and monuments. Current entomological research is focused on Colorado mosquitoes and the West Nile Virus they vector, seasonally working as Surveillance Manager for Colorado Mosquito Control, Inc. He has also been presenting insect-related educational programs for more than two decades to audiences of all ages, including the current award-winning incarnation, "Dr. Mike's Bag of Bugs." He earned B.A. and M.A. degrees in biology at the University of Colorado at Boulder and is currently an adjunct curator at the University of Colorado Museum. He received his doctorate in entomology from Colorado State University and continues to serve as an affiliate faculty member.
