Mike, "ridge" as in "Oak Ridge Rd" implies to me an elevated location not near water, and thus dry. So I'm surprised at the species. Is this a high meadow or something?

Humulus is cool, how do you differentiate that from echo? Is it just lightly marked vs echo?

The part of Oak Ridge road I was collecting at is basically a hilltop covered in forbs, shrubs and oak/aspen trees with lots blooming.

Mostly hilltoppers but some other things.

More lightly marked, different flight period and only found near host.

That is quite a list. Amazing that you can find that many Speyeria in one location.

In late summer sometimes there isn't much nectar so when there is a good plant area it can draw in lots of leps.

I still find it amazing that there is so much variety and abundance of insect life out in the western states despite all the reports of extreme droughts and occurrences of flash flooding which have been all over the news this summer.


Nature finds a way....

Love the photos Mike. It's such a different environment than what I am accustomed to, either in eastern USA or As/Pac.

Here are some pictures of Colias from my late summer trip:


Image

Bottom two are Colias skinneri from the Bighorn Mountains in Wyoming, the two columns on left are Colias christina from the Bighorn mountains, I love how there is so much variation in females of this species. Third column is a male christina from the Bighorns and a female Colias interior from Deer Lodge County Montana. Column on right is Colia alexandra from Muddy Mountain in Natrona County Wyoming.

Interesting! At first glance I thought "oh, philodice and eurytheme" so upon reading the data it was rather a shock. Pretty impressive.

Are these grass field/roadside captures or do they occur in (what is to my mind) dry mountain scrub?

MikeH, I am green with envy! Several years ago I traveled to the Bighorn Mtns. to collect. The day I arrived some big fires broke out high in the mountains, and all the roads above about 8000' were closed to all but emergency traffic - both the northern and southern routes. Collecting the higher elevations was totally impossible, and I came home empty-handed as far as Colias were concerned. I did get some nice Speyerias and a few other things, but my dreams of Colias were a bust.

Very nice indeed MikeH.

It's nice to see some species from out west as none of this can be found east of the Mississippi.

You are very fortunate to live out west (encountering all those panoramic views) along with the ability to collect so many varied species of Colias.

Great hunting and post pictures of that nice western stuff whenever possible...☺️

The alexandra is the prairie subspecies 2nd brood that lives in rather terrible looking dry grassland/sagebrush with rabbit brush shrubs as the attractant. Like this
https://maps.app.goo.gl/Qx9oT6oE81CkbZPx8

Skinneri/interior tends to live in forest edges/open forest where the host blueberries live. In the Bighorns with skinneri that tends to be subalpine forest and meadows like this
Image

For christina, I am still not quite sure where they like to be the most, this is the first time I have found this subspecies in numbers and I don't know if the behavior I saw was typical earlier in the flight. I have found them at a variety of elevations but they seem to like moist forest openings/meadows the most.
I have found them occasionally in the same high elevation forest edges as skinneri.
