Praying Mantis Blessings

I found a praying mantis in the house (not mine). What a treat! I had just come in from the back yard picking a ton of mating Japanese beetles off the peach trees when I spotted it above the door. I'm glad I was the one to see it because I'm sure it would have otherwise been killed for sure. They're not as accepting of bugs...even if they're beneficial. Anyhow, it was the 'boxing gloves' and pose which made me do a double take and go...is that a...??? =O of course, I let it out. =) Maybe it'll invite his friends over and a make a good meal of the other Japanese beetles I couldn't get to. I believe they are a sign of good garden! Maybe not...?
