Sulphur Spinners?

[jayL]

I've never seen a "rust" colored sulphur spinner. I agree that they probably take it based on the profile.

Jay, to my knowledge, our sulfurs are primarily consisted of 2 species. The smaller is dorothea (size 16-18), the larger are invaria (size 14-16). Dorotheas, in the dun stage, tend to be lighter colored, almost white in some cases, whereas the invaria's are more a yellow or orange. Both darken in the spinner stage, dorotheas to a more typical sulfur color, and invaria to orange, or dark brown (rust) type color, almost similar to a hendrickson.

Yeah, I've just never seen one in person. I've fished heavy invaria spinner falls on all of the big four, and they were all only slightly darker than the duns.
