A Stained Trepanedoris
I started learning how to do stained glass pieces over the summer, and for my first piece I decided to honor our Discovering Insect Species class by doing the head of an undescribed species of Bembidion (Trepanedoris) that we discovered. I … Continue reading
Discovering Insect Species: the Trepaneleven Awards!
In the Discovering Insect Species course, the eleven of us (students Alex, Ana, Danielle, Elle, Julia, Mamo, Shannon, Tom, and Trevin, plus John and me) formed a great team, and we learned a lot together. Over the course of the … Continue reading
Discovering Insect Species: Overview in Rearview
When last I blogged, the Discovering Insect Species course was in full swing; we were excitedly waiting for the DNA sequence results from our first big field trip, which was to Klamath Marsh National Wildlife Refuge. I’m sorry I didn’t … Continue reading
Discovering Insect Species: DNA magic in Arizona
I got the email from FedEx saying that our package of four plates of 384 PCR samples had arrived at the University of Arizona, where they will be sequenced. These plates contain the DNA from multiple genes from over 120 … Continue reading
Discovering Insect Species: the beetle DNA heads south
In an earlier post, I outlined the steps we took to extract and amplify DNA from the beetles we collected in the Discovering Insect Species field trip to Klamath Marsh. As mentioned, the students extracted DNA from 36 beetles, … Continue reading
A nematode-filled Bembidion canadianum
Shannon, a student in the Discovering Insect Species course, went down to Eugene last weekend and looked for Trepanedoris. To say that she did well would be an understatement. She caught all four species that I had seen from the … Continue reading

The Bembidion acutifrons story
There are a number of subgroups within Bembidion subgenus Trepanedoris whose structure of gene flow and species boundaries are not understood. The morphological data indicates several forms within these subgroups, but whether this variation is indicative of separate species is not yet … Continue reading
Discovering Insect Species: Klamath Marsh!
We had a great trip last weekend to the Klamath Marsh National Wildlife Refuge as part of our Discovering Insect Species course. One of our main goals was to see what species of Trepanedoris lived in the large marshland complexes of southern … Continue reading
Discovering Insect Species: state of the art in Trepanedoris
As mentioned in my previous post, I outlined the state of the art in Trepanedoris research to the students in my Discovering Insect Species course. Here’s the story I told them. (As the class will be focusing on Trepanedoris in … Continue reading
