Nomada sp. Resting

This little bee was acting really odd. It was walking around on blades of grass quite docile and then latched itself onto this blade you see by locking on with its jaws. We thought it had been parasitized because it was not letting go for anything and then folded its legs up.

I took some photos with the blade bent over a leaf cause the wind was swinging it all over. I wasn't going to post these, just was going to get an ID.

While looking around for the ID, I came across someones photo and one of the comments on it was 'lucky you, wish I could find one with locked jaw', so this got me thinking...why would you want to do that, what is this behavior.

So beginning my top notch detective work with a google search of 'Nomada locked jaw', I was rewarded with results that told me this bee is trying to sleep. I found this very interesting, and had never heard of such, maybe lots of insects do similar but we had never seen it.

I was unable to get an exact ID also, Bwars didn't have an exact match, so if anyone has an idea on that too, I'd appreciate it.
