Moved from Western Tree Cricket.

Moved from Oecanthus. According to Dr. Thomas J. Walker: "Because the cricket is from Washington and the basal two segments of the antennae are pale while the remaining segments change progressively from very dark to light (with the proximal segments being the dark extreme), this picture seems surely to be O. californicus."

...which extends up the antennae. If this were a Snowy or Riley's, the proximal antennae would be very pale green or white. The proximal antennae on this tree cricket almost look black, very dark red. I believe it is a Western Tree Cricket. Reddish proximal antennae segments with black antennae = Western; Red antennae = Broad-winged. Plus based on location, it is probably a Western. I'll ask Dr. Walker to check these photos (as well as the others you posted of the possible Snowy vs. Riley).
