Well it was new to me!

During our road trip, we collected a lot in the El Dorado/Tahoe area of California. Here I encountered some Tenebs that are very common but I had not collected yet (mostly because this really was my first trip to this part of California). I knew that these beetles were common as all the major collections I've been to has hundreds of specimens, but it was still exciting to see them first-hand, alive.
This little guy is Bius estriatus.

It is in the same tribe as Tenebrio and asides from the color (one of the few non all black Tenebs I caught during the trip) it doesn't look all too odd. I expected to find these under bark as thats where I found its relatives out East, but this fellow was inside of a Polypore.

This next critter is Scotobaenus parallellus.
Again, very common in California, but new to me! This clunky fellow is also similar in behavior to the East Coast Tenebs I was used to chasing. They spend their days under bark, preferring dry trees over moist. Then once the sun goes down, they come out and slowly crawl along logs.
