I've been scrolling and scrolling through thousands of beetle photos, starting with an image search (hopeless), then BugGuide, looking at Fungus beetles (only 200 pics) then on to iNaturalist; more fungus beetles, then widening the search; one project on iNaturalist, Beetles of BC, lists 4,000 species, with good, clear photos of most (that's a help!). I looked at them all. And didn't find my beetles. My eyes hurt.
So here's why. I took a photo of a bracket fungus on a log behind the parking lot at Elk Falls. They're common enough that usually I walk on by, but the it has been a dry summer and the usual mushrooms and slime molds weren't visible. So the shelf fungus lucked out.

Red-belted polypore, Fomitopsis mounceae. |
I had taken the photo from a fair distance away, and it wasn't until I got home that I looked at it closely. Then I saw the beetles.

Fungus-loving beetles, unidentified. |
I've been trying to identify them ever since. I looked first under beetles that feed on polypore fungi; that led me to a wider group of Tooth-necked Fungus beetles. (They have tooth-like projections on the side of the thorax.) Some looked almost right, but not quite; dark brown beetles, small, pointed oval shaped. And with a definite white band across the front end of the elytra, the hard wing covers. It is that white band that is the problem; expanding to all the beetles in BC, I found a few similar, but they were diving beetles; the wrong shape, the wrong habitat.
He estado examinando miles de fotos de escarabajos, empezando con una búsqueda por imagen, sin suerte, luego pasando a BugGuide donde miraba escarabajos que viven en los hongos (de estos, solo hay 200 fotos). Luego, no encontrando lo que buscaba, llegué a iNaturalist, examinando primeramente los escarabajos de los hongos, y después ampliando la búsqueda; un proyecto en iNaturalist, Los Escarabajos de Colombia Británica, incluye 4.000 especies en su lista. Las miré todas. Y no encontré las mias. Y mis ojos se sienten quemados.
¿Porqué? Saqué una foto de un hongo políporo en un tronco atrás del estacionamiento de las cataratas Elk. Son bastante comunes, y generalmente paso sin detenerme, pero este ha sido un verano seco y los hongos y los mohos mucilaginosos que encuentro en este sitio no se hallaban visibles. Pues entonces, saqué esta foto del políporo.
- Es un políporo Fomitopsis mounceae.
- Y aquí están los escarabajos.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.
Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
