blanketflower mothThe Blanketflower Moth (Schinia masoni), master of camouflage, assumes this position on the Blanketflower, matching its color pattern to that of the flower. Does the blood rush to its head? Its caterpillar eats the flowers and seeds of this plant.
uhleri Uhler's Arctic (Oeneis uhleri) nectaring on a mustard. This Satyr whose caterpillars eat grasses and sedges is a shy butterfly. It's short flights end in a rapid dive to the ground where it is well camouflaged.
weidemeyers admiralWeidemeyer's Admiral (Limenitis weidemeyerii). We can almost always find this favorite in our small canyon perching on one special Juniper or patrolling back and forth. Here grow Serviceberry, Chokecherry and Willow, the host plants.
cressons ctenuchaCresson's Ctenucha (Ctenucha cressonana) is in the Tiger Moth family and Wasp Moth subfamily. Notice the resemblance to a wasp. The caterpillar food plant is not reported, but we have observed this moth laying eggs on blades of grass.
parnassian caterpillar Rocky Mountain Parnassian caterpillar. We found it under its foodplant, Yellow Stonecrop. This mature caterpillar, 2" long, soon pupated.
parnassianpapillioRocky Mountain Parnassian (Parnassius smintheus) a tailless mountain swallowtail, has Casper -the-Ghost-like whitish translucent wings. Its caterpillar eats our Sedum, Yellow Stonecrop.
green grasshopperGreen-stripped Grasshopper (Chortophaga viridifasciata) pair. Female is green, male is brown. We see it in early spring.
milkweed longhornMilkweed Longhorn (Tetraopes femoratus) pair on Showy Milkweed, the plant both adults and larvae eat. The male is a shrimp!
snaketail dragonflyThe Pale Snaketail (Ophiogomphus severus), is a fairly common dragonfly in our small canyon where it often perches on the sandy trail. Notice the enlarged last few segments of the abdomen, a characteristic of its family, the Clubtails.
wolf spider hawkWolf-Spider Hawk (Tachypompilus ferrugineus), a close relative of the Tarantula Hawk, is a magnificant wasp that we see visiting the flowers of Virgin's Bower Clematis vine. In early morning we find them still sleeping among blooms.
