Colorado Camping Vacation

My wife and I made a camping excursion to the Vallecito area of s.w. Colorado, August 7-15, to momentarily get out of the Texas heat. (A great many Texans were apparently doing the same thing!) I’ll have many observations to upload including a boat-load of plants from NM and CO. I thought I’d start with the “low-hanging fruit”: I put up a moth sheet in the Forest Service campground at Vallecito on three evenings and had good results. In all, I probably documented something just shy of 100 species of moths. The first uploads will exhibit some of the more recognizable macromoths such as the few dozen species of Geometrids that showed up. There will also be a rather bewildering array of dark mottled Noctuids and many small grayish micros. The habitat at our campsite (7900 ft elevation) was Ponderosa Pine-Douglas Fir forest with some understory of Aspen and Gambel’s Oak. We were close to a steep mountain slope with much Blue Spruce, Limber Pine and a variety of understory plants.

Identifying these moths from the Rockies is just good brain exercise. Keep checking back.

This is the closest match I can come up with among many similar species. In particular, the shape of the AM bands and the brown subterminal shading appear to point to this species.

A key character separating G. minima from others in the genus is supposedly the lack of brown shading on the basal side of the AM line, but that is belied by many/most online images of the species. The shading is less obvious than other species, but it is clearly present.

The heavy dark shading on this examples seems to place it squarely with Gabriola regularia which occurs in nearby NM and AZ, but I can't find CO records of the species. I may be off here.

Moths of the genus Galenara were among the most common Geometrids on the moth sheet each night. The patterns are dark and somewhat obscure and just enough variable that identification to species is a bit tricky with my lack of experience with the genus. I'm uploading several individuals in separate observations for each night of mothing. Most appear likely to be either G. lallata, or less likely G. stenomacra, two species known to occur in SW Colorado.

I think I've properly placed this reddish brown Geometrid. My two images represent two different individuals on the same night, one of which was hiding at the base of a rock. Compare with the Jim Vargo example on MPG:
http://mothphotographersgroup.msstate.edu/species.php?hodges=6695
and a number of examples on BG:
https://bugguide.net/node/view/1420491/bgimage
There is quite a range of ground color exhibited in the uploaded images placed as this species, ranging from dark gray to reddish brown. I am assuming they are all properly identified.

I can't settle on what this Geometrid might be, but I think it is within the Ennominae subfamily and probably in this tribe.

I was trying to pigeon-hole this moth into one of the common Crambus species when I noticed the strongly falcate wingtips which seem to point to this genus.

Even some of these fairly distinctive Noctuids have been tough to ID. Steagrotis vocalis is a Rocky Mountain and Great Basin equivalent of S. pallidicollis of the Pacific States. The pale buffy wash through the inner part of the FWs here suggests that this is a male.

Here's the next batch of somewhat identifiable Noctuids. They get more difficult after these. I have only modest confidence in my IDs of these Andropolia moths. The grayer examples seem to best match A. contacta. The rich buffy examples match A. theodori, I think.

I finally settled on this ID after wandering through MPG, Lafontaine's MONA fascicle (1987, fasc. 27.2), and BOLD examples. In particular, a difference between E. auripennis and the very similar E. servitus is the simple margin of the dark terminal band on the FWs as in these examples. E. servitus has a more jagged, streaked edge. See for instance, the examples of E. auripennis on this BOLD page:

BG doesn't have a page for the species.

This matches the description of the (very) blackish form of Apamea indocilis in the Mikkola et al. MONA fasc. 26.9 (p. 45-47). This moth lacks the "bronzy tones" of the similarly dark A. plutonia. MPG has images only of the lighter form of indocilis.

A few examples on the BOLD website appear to show the dark form.

Now I'm getting into some of the last and toughest IDs among my Vallecito moths. Here are four records of what I distinguish as three different species of the Pyralid genus Dioryctria which feed on conifers. I'm fairly sure I can narrow down the present two examples to #5841 D. abietivorella. This is a boldly marked black and white species with few or no brown or buff tones (Neunzig, 2003 MONA fasc. 15.5). The FW length on each of these examples is 12 mm.
