nice -- check Euderces picipes...

...and wait for 2nd opinion :-]

Thanks again!

I had a look and it sure is another possibility, but there is that mark just visible under the front leg of the presumed female which still makes me lean towards N leucozonus...Also, N leucozonus is common and widespread here (many specimens), whereas E picipes would be new and is a "hardwood species that prefers redbud, hickory", which don't occur here naturally, but I wonder what other trees it can use. These main trees are much more common in southern Ontario and Quebec, where E picipes has been found to date in Canada. But, I still await a second (and third) opinion, especially given the partially hidden characters. I will do my best to get a better photo by June...

Cyrtophorus verrucosus (Olivi

Cyrtophorus verrucosus (Olivier, 1795). There are too many white markings for Euderces, and I don't believe there are any Neoclytus with the bumps at the base of the elytra.

Thanks!

Yes, that works for me too, especially given that it is a common species here. I hadn't noticed the bumps, but then I'm quite new at this group of insects. Much appreciated!
