Thanks for your help Dorie, they look like have a longer body than longhorns, and thinner legs. It looks much thinner to me than the picture you showed the link to.
It looks like one of the long-horned beetles that damages diseased and dying trees. The adults visit flowers to obtain protein -- pollen -- needed in order to produce eggs.
Hereabouts, I'm currently finding Leptura oblitera on my Hydrangea paniculata -- they're eating pollen and mating.
I can't see adequate detail in your photo to determine if it's the same species. And I don't have my reference book handy to double check.
