Often people lump all carabid beetles in to the “generalist predator” bin, but there are many, many exceptions. Here is an image of an Amara sp. (I haven’t gotten around to identifying it yet) that was climbing the grass during the day around the edge of Mono Lake. I saw many individuals doing this and watched them feeding, apparently on the pollen. I took the picture back in July of 2010, but just last week I watched one Pterostichus feeding on the husks of California Bay nuts and another eating the nut meat out of an acorn that was broken open. Last night found two different species of Scaphinotus at Portola SP feeding on fallen fruits of some sort (some were Madrone fruits, I think). Not that these NorCal beetles have gone vegan, they just are able take advantage of any good protein or sugar source.
