The Great Olive-winged Drake is
sometimes called the "Michigan
Caddis". It is a huge mayfly that is
found in the East, Mid-west and
some Western trout streams. It
prefers slower moving and still
water. Both the duns hatch and
the spinners fall in the evenings.
This is a very popular mayfly in
some trout streams.
