Yes they are different (I prefer black raspberries smaller seeds more punch)
In my neck of the woods, Illinois, black raspberries are finished and
blackberries are in. The way I tell them apart (outside of flavor and
texture) is when you pick a black raspberry a small cone is left on the
plant, when you pick a blackberry it comes off the stem square or with no
cone remaining.
