Cream Cahill Dun

The Cream Cahill is a common name that includes several clinger species of mayflies. They are somewhat difficult to describe in that they are light colored mayflies even much lighter in appearance than the Light Cahill. The colors of the Cream Cahill will vary based on the locale and based on the individual species. While the nymph’s appearance is almost identical among the species, the duns can vary in appearance. All the Dream Cahills have a creamy or beige to white shade of body with a darker thorax and they all have pale gray wings, but the markings will vary.

Note: The Cream Cahill spinners are usually the same as the duns except the wings become transparent and the front legs and tails become much longer. The body of the spinner becomes darker in color becoming browner in appearance.

The Cream Cahill mayflies hatch mostly in the late afternoons or evenings and as the days get warmer, the hatch will occur later in the day.
