Sorry about this confusion...

...two editors with much more taxonomy knowledge than I have fixed the Taxonomy list -- so this image is where it now should be.

Could be Snowy....but can't rule out Riley's

Since this tree cricket was located in Oregon...both species occur there. The only thing setting the two apart is the size and location of the black spot on the 2d antennal segment.

Snowy: The spot is at least 1/2 the length of the segment and is centrally located.

Riley's: The spot is less than 1/2 the length of the segment and is located nearer to the top edge of the segment.

I'm going to move this to the rileyi group -- if you happen to have a photo of the antennal segments from the top or front, we might be able to make a definite ID.

Either way, this is a great photo for the guide. It helps point out the similarities between these two species.

Snowy vs. Riley's Tree Cricket

Unfortunately I don't have another photo of this cricket. Should I see another one I will know better.
Thank you for the help
