Sometimes honeyberry and haskap are used interchangeably to refer to edible blue honeysuckle. Often, haskap refers to later ripening and larger blue honeysuckle berries, typically containing more Japanese genetics. Meanwhile, honeyberry often refers to earlier ripening and smaller blue honeysuckle berries, typically containing more Russian genetics.

Below is one of the smaller honeyberries, either Tundra or one of the Indigo series, propagated by Dr. Bob Bors in Canada, and one of the larger haskap berries, Maxie, propagated by Dr. Maxine Thompson in Oregon. It should be noted that Dr. Bors has propagated a larger size Boreal series of blue honeysuckle berry using Japanese genetics and refers to the fruit as honeyberry. So the terms are partly interchangeable.

As evidenced from these photos taken this day, ripening time can greatly overlap.
