Nancy and jim:



One subfamily of Cerambycidae is the Prioninae, sometimes called prionids.
There are two species in this group in NS.  I suspect this is *Orthosoma
brunneum*, referred to as Brown Prionid on BugGuide.  The larvae feed in
roots and even the bases of telephone poles.  They must be tough!



The other species is *Tragosoma harrisii *(previously considered as part of
the Old World *T. depsarium*).  It lacks the spines on the side of the
thorax that *Orthosoma* has.



I suspect both are reasonably common in NS, but they are infrequently
collected.
