Interpretation of the Flight-Phenograms
  implies low numbers: either just starting, or the very ending of the flight period
  implies more steady numbers coming to light
  implies still greater numbers coming to light (building toward an apparent "peak")
  an obvious or clearly undeniable peak in numbers




Even with the less common spp. (B- down to D), "peaks" can still be quite apparent, even though the actual numbers coming to light will be vastly lower for the scarce species than for those rated in the B+ to A+ range.... This is why the abundance-ratings are stated separately, alongside the phenograms (date-grids), because entirely different information is being conveyed. When there doesn't seem to be any apparent "peak", then only the ( X ) or ( / ) marks are used throughout the entire phenogram. Also, it should be noted that certain spp. simply do not come as readily to (uv.) light as do others! In such cases, a moth rated as B- or C may, in fact, actually be more abundant in this locality than I realize but I may have no other feedback alerting me to the discrepancy.... And, there may also be at least a few(?) nocturnally active moths that simply are not attracted to uv. lights at all a question that will have to remain unanswered, if they are strictly nocturnal in their flight activity!.... Some of these "elusive" moths may be attracted more readily to mercury vapor or incandescent lights an area I have not been inclined to explore in any depth.... And (vice versa), it may also be true that certain moths come more readily to ultraviolet lights of certain wave-lengths, than they do to any of the various brilliant mercury vapor lights again, in need of investigation by those who find this topic of interest. The uv. lights I have employed ever since 1956 (G.E. or Sylvania, "F15T8/BL"), bring in such huge numbers of moths (on good nights) as to more than overwhelm my limited processing capabilities and available time.... Thus, I have NO interest whatsoever in attracting even greater numbers of moths!
Five Acres of Moths

A long-term study documenting the occurrence of more than 900 macro-moth species on 5 acres in lower ASH CANYON (oak/manzanita woodland and grassland ecotone, at 5170 ft. elevation, 13 mi. S. of Sierra Vista).
