With the death of James Murray, marine biologist of the CAE, after the sinking
of the Karluk, all the work of collecting invertebrates fell on the shoulders
of Fritz Johansen. As a result, the number of insects collected was fewer than
expected. In spite of this, the collection of insects brought back by the CAE
added valuable information to the knowledge of the insects of northern regions.
Over ninety new species, eight new genera and five new subspecies were described,
based on the CAE collections. These specimens continue to be of value for revisions
of insect classification. With the extensive information on insect ecology recorded
by Johansen, the insects collected also give an important baseline for current
studies of climate change in the Arctic.
