lastly then, the Blues, and skippers...
Melissa Blue,
Plebejus melissa , in Sagebrush ultra-dry scrub with buckwheats and Lupines, SSB sized...
The similar but slightly larger Acmon Blue,
Plebejus acmon, found in more flower and Lupine rich scrubby grasslands...
The similar but tiny Ancilla Spotted Blue,
Euphilotes enoptes ancilla, found with the Acmon Blues,...
Boisduval's Blue,
Plebejus icarioides, found in almost every suitable looking flowery place, Common Blue sized, as were the following three species,....
Another
Plebejus species, but seems much closer to
Glaucopsyche in appearance, to me, the Greenish Blue,
Plebejus saepiolus.This was the least frequently encountered, but a noticably different shade of shining blue in flight..
and to illustrate that... the Silvery Blue,
Glaucopsyche lygdamus, almost as frequent as Boisduval's ...
My most favourite butterfly of the trip, Arrowhead Blue,
Glaucopsyche piasus, found in dry sagebrush mainly, seen on three occasions ...
Lastly, a couple of worn singletons seen, both from small well watered, openly forested gulches....
Spring Azure,
Celestrina ladon, which was Small Blue sized...
and presumably Western Tailed Blue,
Everes amyntula, Short-tailed Blue sized,...
Of the few Skippers, relatively, here are...
Persius Duskywing,
Erynnis persius...
Rocky Mounain Duskywing
Erynnis telemachus, (according to distribution)...
A worn Two-banded Checkered Skipper,
Pyrgus ruralis..
and finally Clouded Skipper,
Thorybes pylades...
That's all folks!
