Chrysomelidae, maybe Lema genus? Zhejiang, China.
I'm not sure what the species (or even genus) is of this marvelous leaf beetle. I collected it just a few days ago on a trail in Zhejiang province, China. I would love some help on the ID if anyone has ideas. I've seen them before in this area and believe they are fairly common.
The above hind wing-display sequence came as a complete and happy surprise to me. I was attempting to shoot the beetle's gorgeous ventral side when her elytra began to open, revealing incredibly bright strawberry-pink hind wings. I believe the spectacle was just an attempt to right herself rather than a threat display? But, again, I'm not sure. Regardless, it was an absolute treat to see.
