Some of you science types probably know some other enigmatic names. Let me know.
As a follow up to my earlier report on the butterflies and diurnal moths of the Pikes Peak Region, I took the advice of Steve Taylor and prepared a graphic of all 255 dates on which I counted butterflies, and on which the time, temperature, and other conditions were favorable to flight. This shows the “noise” encountered in this sort of work, as well as the extraordinary summers of 2012-2014. If there is a trend, it might show up as a decline after 2015, when levels are about as they were early in the study. Note that most of the points from 2015 on fall below the mean score of 72.5/h. However, the overall slope is very slightly up (+0.032x). I can’t wait to continue observations this summer.
If I restrict the data to just the 145 dates that are from Bear Creek Canyon, there is a very slightly different trend, this time downward (–0.12x), from about 91 to 74 over the 35 years. Maybe this is the apocalypse! More later!
We keep a patch of milkweed in the back yard, and several patches of excellent nectar sources for butterflies. My favorite colors are monarchs on Tithonia. Check these out.
And then, of course, the milkweeds. Here it seems necessary to quote part of the great Richard Wilbur poem, “Two Voices in a Meadow.”
Anonymous as cherubs
Over the crib of God,
White seeds are floating
Out of my burst pod.
What power had I
Before I learned to yield?
Shatter me, great wind:
I shall possess the field.
After 33 years of collecting moths in the Pikes Peak Region, I finally have begun to let it go to the C. P. Gillette Museum in Fort Collins at Colorado State University. The first installment, 36 drawers of mostly Noctuidae (the owlet moths) were shrink-wrapped and dispatched on August 29. One drawer is shown here.
And here is the first load.
And in their new home.
Many more to go in the next few weeks. Sad to see them go, but I know that they’re in a better place. (!)
