Insects and other foods the trout may be eating:
1. Blue-winged Olives (Baetis) - sparse hatches
2. Blue Quills - hatching
3. Quill Gordons - hatching
4. Hendricksons - could start any day now - nymphs are important
5. Little Black Caddis - hatching
6. Little Brown Stoneflies - hatching
7. Midges - hatching in isolated locations
8. Streamers - matching sculpin, baitfish and small crawfish

Hendrickson Spinners:

The spinner fall is the main event of the Hendrickson hatch. The male spinner is
called the "Red Quill", however, there are a lot of other mayfly spinners that are
called "Red Quills". Besides, who said the male spinners are the main ones the
trout eat. I think it is right the opposite. The female spinners are the main ones
eaten by trout. The reason I believe so is because the males fall dead as soon as
they mate. They may not even fall over the water although most of the time it does.
The males die prior to the female spinner fall. The females fly down to the water
and either drop their eggs from the air just above the water or by touching the
surface of the water with their abdomens. This usually occurs just prior to dark. It
may start earlier on dark, cloudy days. The females deposit their eggs in the same
water they hatched from but the males mate wherever it is convenient, usually over
the water. Sometimes they mate high in the air and they often fall on the banks.
Because of when and where the spinners fall, I think the females are much more
apt to be eaten by trout although I am certain both sexes fall prey to the trout. The
bodies of the two sexes are completely different colors. That is why we have two
pattens of Perfect Flies for the Hendrickson spinners. In theory, you could fish the
male version earlier and the females later in the afternoons.

When the spinner fall is fairly heavy, the trout tend to get into the feeding lanes and
develop a steady rhythm eating the spinners. There can be a lot of spinners on the
water at one time. They all fall within minutes. We use both an up and across and a
down and across presentation of the spent spinners depending on the situation. If
we see the trout sipping the spinners in feeding lane we generally try to fish up and
across to them. If they are feeding at the ends of long runs and riffles, or at the
heads of pools where they tend to collect, we usually fish down and across. You
should choose the method of presentation based on how well you will be able to get
the fly in the right place without spooking the trout.
