Hey! Another fellow oregonian! Not enough of us around.
I just caught one around 30 minutes ago while they were flying. I just walked around and waited till I saw one that had landed and nabbed it with some Tupperware (what I had with me at the time) and then transferred it into a test tube when I got home. Just make sure it's not right next to the entrance of an ant hill, as it likely hasn't mated. Good luck!
edit: the stuck out tongue emoji look wayyy different than I thought it would....
