Discovering Insect Species: hands-on with Trepanedoris
I’m a bit behind in posts about the Discovering Insect Species course, because so much has happened so quickly. Last week we examined our catch from the local field trip and learned how to prepare specimens, and we learned the state of … Continue reading
Discovering Insect Species: taxonomic history of Trepanedoris
In the scientific literature, there are now considered to be 16 species of Bembidion subgenus Trepanedoris. What path of research in insect systematics has led us to this point? In 1758, when the tenth edition of Carl Linnaeus’s Systema Naturae was … Continue reading
Sharing the joy of discovery
Nine undergraduate students, my graduate student John Sproul, and me. Over the next ten weeks we will go into the field, find beetles, look at them under the microscope, do dissections, photograph them, make predictions about species boundaries, extract their DNA, PCR … Continue reading
Return of the Taxa
Those who might follow my blog may have noticed a rather long lull in my posts. For this I apologize, but life happens, and my attentions were elsewhere. I hope to make up for that in the coming months. In the meantime, … Continue reading

Here’s a lovely creek in the Cascades of Oregon. This part of Sheep Creek is at 795m elevation. It has a rich bembidiine fauna living in the gravel patches along the shoreline. In addition to two species of Lionepha … Continue reading
Dreaming of Saint Helena
Saint Helena is a small island in the Atlantic Ocean that is a very long way from any continent. It is approximately 1850 km from Africa, and about 3290 km from South America. It is only 16 km by 8 … Continue reading
Examining name-bearers at the USNM
I’m at the Smithsonian Institution for the next three days, working in the United States Museum of Natural History (the “USNM”). My main goal is to look at type specimens, especially Casey types, so that I can figure out what … Continue reading

Lindrochthus at Mount Tamalpais
In an earlier post, I wrote about how the distinctive subgenus Lindrochthus, viewed in the literature as consisting of the single species Bembidion wickhami, was actually at least two species. And those two species live together at Mount Tamalpais, just … Continue reading
