Oddly, these show up every night for the last several weeks or so. I posted an ID request for one a few weeks back but was not id'd. In almost every case, the patterning is different, enough so that it really catches your attention. I'll take more pics of these in hopes it will further what is already known.

Lactura subfervens
Of the six species names presently used for North American Lactura, three of them apply to moths such as this one, in which the forewing has two diagonal rows of spots and is covered, to a greater or lesser degree, with small, uniformly-distributed dark-brown flecks. One of these three species, basistriga, is readily diagnosed by its pink collar. The remaining two names, subfervens and psammitis, refer to moths such as the one seen here, in which the pink collar is absent.

The name psammitis was formally synonymized under subfervens, and the grounds for this action explained, by Barnes and McDunnough 1913, Contributions 2: 143 (see here), but psammitis since has resurfaced, apparently as of the 1983 checklist. I am not aware of anyone's having published an explanation of why this was done (or of how, if possible, to tell the two apart on sight). Until or unless that happens, it probably is safest to call everything subfervens that answers the above description.

 
Thank you for taking the time
