Identified!
Judging by the honker on this one, I'm almost 100% sure that this one is Ringo.

Orsodacninae Subamily?
It looks a bit like this subfamily from the Peterson Field Guide. Specifically the Orsodacne atra. However, I don't even know if that species is found in Cananda. It does like flowers and is found in the Spring.

Orsodacne atra
Thanks Lynette - and Zack - for the ID. I had trouble with this one because it looked sort of leaf beetle-ish and sort of longhorn beetle-ish. Where should the Guide page be put? In Chrysomelidae, Orsodacnidae, No Taxon, or left "floating" in the Chrysomeloidea superfamily?

Guide location
The Peterson Field guide (1983) places it in the Leaf Beetles - Chrysomelidae. But, I don't know if that's the most current or accurate placement. This site (2003) has it listed as its own Family.

Orsodacne atra (Ahrens 1810)
Lynette-
Good eye- it looks like you're right on. This is
Orsodacne atra
, the only species in the genus. Apparently, this species is extremely variable in color, which has spawned numerous dubious synonyms and subspecies.
Whether its parent taxon is a subfamily (Chrysomelidae: Orsodacninae) or a family unto itself (Orsodacnidae) depends on which authority you follow.
cheers,
zack
