BotW: Sphaeroderus
At last, a beetle of the week! However, it’s been so long since the last one that I should probably rename the feature to be “beetle of the season”, or “beetle of whenever”. Here’s a beautiful Sphaeroderus from North Carolina. … Continue reading
And then there were five…
Earlier this week I spent three lovely days in the Bay Area with Dave Kavanaugh, and on Monday we went to collecting on the slopes of Mount Tamalpais. There, along Cataract Creek, we found a series of small “Bembidion curtulatum” … Continue reading

Time is the coin of your life
In my wallet I have a fortune from a fortune cookie which I opened long ago (I don’t remember where or when). It says: Time is the coin of your life. It is the only coin you have and only … Continue reading
Bountiful Bembidion
Bembidion can be quite abundant on the shores of bodies of water, such as along the Willamette River near Corvallis, Oregon: Below are two videos showing me turning over some rocks on shore shown above. There are four species that … Continue reading

Chipodiversity
This summer my lab has had, once a week, a “Guess the Potato Chip Flavor Day”. It was inspired by my discovery in Vancouver, BC, of some intriguing potato chip flavors. While growing up in Canada I was exposed … Continue reading

Mirror, mirror, …
… but not on the wall. This image hurts my brain. A lot. I suspect that other folks who study Bembidion have sore brains as they look at this, too. Why?

The excitement of discovering patterns in nature
When a pattern in nature emerges, suddenly revealed through new data, I get a high unlike any other. It is this aspect of systematic and taxonomic work that I like the best, which keeps me enthralled, and which I crave … Continue reading

“Local” carrots
Here is a bag of carrots. They were grown at a farm just outside of Corvallis, Oregon. I bought them at the Farmers’ Market here in Corvallis. I ate them in Corvallis. And while I should feel pleased to have … Continue reading
3D printing and custom tools in entomology
I am excited about 3D printing. Here’s why: That’s a pinning block, an aid to pinning insects. It’s a custom-designed one, however, not the standard sort you can buy at an entomology supply company. This one is specifically built for … Continue reading
