The common large black Camponotus species here in CA are C. vicinus, C. laevigatus, C. modoc, and C. quercicola. I have found all four of these this season but this does not look like any one of them.
Does not appear to be C. modoc (no dense yellow hairs or alternating matt black stripes on gaster), C. laevigatus (hairs are not white and no C. laevigatus have red hues on their legs. C. laevigatus also much shinier), or C. vicinus (hair density and head to thorax ratio incorrect).
Could this possibly be a "northern" variety of C. quercicola?
** Will post macro shots when they are taken, but have attached a short cell video for now **
