Glen Cove, Pikes Peak treeline, on Sedum rhodanthum flowers.
One of my favorites: The Caracara, which means “Faceface” in Spanish. Doesn’t it? Well named!
And stilts. How about those legs!
Green jays are common along the Nueces River.
And scissor-tailed flycatchers. Wow!
Black-bellied plovers are in the Gulf bays.
Looking back, this was one of the best summers of my life. To begin with, it was the earliest spring in my fifty years of record keeping, with emergent butterflies flying in February, and a strong flight through March. Then the huge May freeze!
Then, red tailed hawks nesting in the back yard. I never imagined that.
Then, other birds, both on the mountain and in the garden.
And mothing! I had the pleasure of collecting moths in several areas, some new to me: Blodgett Peak Open Space, Ute Valley Park, Bluestem Prairie Open Space, Rock Creek Canyon, and Baculite Mesa. Keeping track of all those moths isn’t easy. I added 37 new records for the Pikes Peak Region, bringing my current total to 2073 species.
And the garden OMG, what a year for the flowers!
And the July rains!
I heard that it was the wettest July on record. So, up came the mushrooms. We found about 40 species on one hike in Bear Creek.
And July on Shelf Road, the amazing rabbit bot fly!
And rare butterflies. The third record of Nymphalis californica and the fourth record of Adelpha bredowi in El Paso County.
Plus many new records of the butterflies like the pigmy blue, Brephidium exilis (photo by Tim Leppek), which reminds me of Eric Eaton and all the new friends I found on the Arthropods Colorado Facebook Group. That’s been a load of fun. (What will we do in the winter?)
So it was an amazing summer. I already have seasonal affective disorder from the 7:30 twilight. I can’t wait until spring.
Albinism and leucism are rare in Lepidoptera. If you google “Albinism and Leucism in Lepidoptera” you’ll find thousands of photos of mammals, birds, and reptiles, but only a scattering of leps, some of which are white species, not leucistics. The obvious exception is a white luna moth, which is normally green. But the photo is labeled “Albino,” while the dark ocelli stand out on all four wings. It is a leucistic. Leucism is caused by recessive alleles that don’t produce the normal pigments. Albinism is an extreme case of this in which all of the alleles are dysfunctional.
I found a Vanessa cardui that is partially leucistic, feeding with hundreds of normal morphs on Chrysothamnus bushes. I show it here with a normal form below.
This morning in the flower garden I found a Siricid, a horntail wasp, a large male, crawling slowly up and down the raceme of a flowering mint. Soon I discovered, beneath him, a second male of the same species, and they seemed to be in some sort of competitive ritual. But, whoa! The surprise is that the smaller male hasn’t moved much because…
Did you see it? After watching them for about three hours, during which time the larger one continued wandering up and down the stalk, I noticed that the smaller one was moving only very slightly. I didn’t realize it until I enlarged a photo afterwards. Then I went back for a better look. Yikes! A crab spider!
Crab spiders are generalist predators that roughly match their substrate, so they qualify as “aggressive mimics.” The phenomenon is also known as “mimesis” when the model is inanimate, or at least not another similar species. Background mimics or cryptic species are mimetics.
Here’s a few photos and a short video of trying to coax a tarantula out of her burrow.
Baculites are fossil cephalopods that formed long rod-shaped “bones,” much like the inner shell of a modern squid. The largest ones may be several feet long, but here at Baculite Mesa they are mostly small specimens.
Here is one of the several preying mantises we found, a male.
And the group, working on the tarantula burrow. We found several at home, but not eager to step into the sunlight.
Here is a mating pair of Phyciodes picta, a desert version of the foothill campestris. It seems to be common in Pueblo County. We found scores of them.
And a whiptail lizard, apparently sleeping through our disturbances.
And even birds, although besides the pond-side doves and killdeer, there were few. Here’s a rock wren, the best photo I could get as it kept moving.
I figured they’d mostly eat tourists’ handouts, but not today!
