Insect Life Cycles
are 4 main food groups for humans - chocolate cake,
chocolate ice cream, chocolate cookies and chocolate pie. Trout have 4
main insect food groups as well as baitfish, leeches, worms and of
course terrestrials. The diagrams below are of the life cycles of the 4
insect groups. What rivers these insects are found in depends to a large
part on the quality of the water. The most susceptible insect to poor
water quality is the Stone Fly. If a river has stone flies then the
water quality is good. The Bow River has a prolific Stone Fly hatch each
June/July and the trout aggressively feed on these insects. Stone Fly nymphs
and Stone Fly adults can be fished with great success. The Bow also
has good hatches of the other insects as well. See the hatch chart for
times of year these insects can be found.
