It's a ladybug. I don't remember which kind, but maybe the one that eats spidermites.

It's like a photo negative Ladybug! I think it's cute.PJ

In the bamboo forum, one person called it a "twice stabbed ladybug

I didn't think it was a ladybug - but those odd babies say "ladybug"

The person on the bamboo forum had it right.
Hope thishref> helps.

I liked the link - didn't realize these other bugs were ladybugs even after all this time. That 7-spot ladybug was interesting.
