I just cannot see the spines on the thorax clearly on my computer to be sure. With most insects, there are more similar species in NS than most of us realize. There are more than 100 species of Cerambycidae, that is long-horned wood boring beetles in NS. Just because we do not know exactly which species, does not mean we should not marvel at them and pay attention to them.
