Love the antennae!
That's a really interesting beetle! The antennae are amazing! Is this a male, or can you tell? I'm glad your group found so many insects at the Gathering, my husband and I were in WA the last 2 weeks of June (Orcas Is., Mt. Rainier, Mt. Saint Helens) and we didn't have much luck finding many insects or spiders. Of course, it helps to have so many pairs of eyes looking, and the moth light at night helps too!

 
Thanks
It does seem harder to find bugs in WA. However, the lights at night really drew in some great moths and a few great beetles like this one!

 
and...
It is a male. I figured it out today from looking at Beatriz Moisset's article here.

 
I found one of these (I think) in CA....
...and it made the funniest sound - just like it had hydraulic shocks. Sort of a "Tzzzzzzzzzzzzz". They make the sound when handled...probably a defense of some sort.

 
defensive hiss
yes, if you make them angry they will hiss at you.

 
If only they realized how amusing the sound was...
...but then we would miss out!
