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
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.

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

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
