Calligrapha scalaris group

Without knowing the host plant, one can't tell if this is C. scalaris or one of the other similar spp. of Calligrapha... However, I'm going to go ahead and move to C. scalaris.

Hostplant

I believe these beetles were found on Basswood--does that help?

Thanks,

It doesn't help as much as I initally supposed...

There are 13 spp. of Calligrapha known from ON. (1)
Five spp. of Calligrapha feed on T. americana and two more spp. are reported from Tilia sp. (2)

However, cross referencing the pattern, the host and the range suggests this is Calligrapha amator which happens to be the only sp. of Calligrapha known only from ON. Will move to C. amator, the Ontario Calligrapha Leaf Beetle... (Keep shoting!)

Beautiful!

Calligrapha sp., but beyond that I don't know for sure. However, there's a similar one that they're calling Elm calligrapha on this Oklahoma State University site, which presumably is Calligrapha scalaris as on this Insects of Quebec site. See also

Furthermore, I see that Cranshaw (1) lists Linden Leaf Beetle as an alternate name for C. scalaris - Linden, as you may know, is another name for Tilia sp. (Basswood).
