Nature Experienceship: Insects in Provo Canyon

On Saturday, September 22nd, we had the fantastic opportunity to go and collect insects with Dr. Shawn Clark, the manager of the Bean Museum’s collection of arachnids and insects. While we waited for it to warm up enough to go collecting, Dr. Clark gave everyone a special look inside the museum’s research collections. Dr. Clark explained that the collecting started with one of BYU’s first research expeditions in the early 1900s.

We didn’t stay there too long before we were on our way to one of Dr. Clark’s favorite collection sites, up past Vivian Park in Provo Canyon. Dr. Clark freely shared his knowledge of insects. We learned that there are as many species of insects as there are all the other species of animals in the world combined!

Once we made it to the collection site, Dr. Clark demonstrated how to collect the bugs with nets, and then preserve them in alcohol.

The first catch of the day was a European Mantis. They aren’t native to Utah. As their name suggests, they made their way over here from Europe. Some other noteworthy catches included: Crab Spiders, Damsel Flies, Millipedes, a Plant Hopper, Paper Wasps, Water Skeeters and a Chrysomelid Beetle. The most interesting catch was a Blue Mud Wasp. When a patron discovered it in their net, Dr. Clark fearlessly reached in to pull it out. With the patron’s permission, Dr. Clark took it with him and the wasp is now a part of the museum’s research collection.

Insects aren’t the only thing we learned about while out in the field. Dr. Clark taught us about watercress, a plant that has sparked scientific debate. It is widely accepted to be native to Europe and Asia, but scientists aren’t sure if it is native or invasive in North America. Dr. Clark believes it is native, because there is a species of beetle, that is native to North America, that only lives in watercress. To Dr. Clark, it doesn’t make too much sense for a trait like that to have evolved in the short span of a couple of hundred years.

In total, we only saw a tiny fraction of the insect and arachnid collection that Dr. Clark manages. There are over 2 million specimens in the museum's collection, including the world’s largest collection of stoneflies! It takes a long time to grow a collection that big. We're grateful for Dr. Clark for managing the collection and for sharing his knowledge with us!
