Chimarra Caddis Larva

Chimarra Caddis Larva 
This bright orange/yellow caddis larva can be an important food source on some waters in my area during the late winter and early spring months.  As far as caddis larva go it is one of the smallest I will bother to imitate.  I tie them on a 3x short hook in sizes 16 & 18, but I know folks tie them smaller (typically 18-20).  The short shank hook allows me to maintain a good hook gap but still keep the body appropriately sized.

I was able to get out this week and enjoy some of the unseasonable warm weather.  This pattern and small patterns with bright orange hot spots produced well, indicating that the fish may be seeing some of these larva already.

Pattern Recipe:
Hook:  3x short larva hook
Thread:  8/0 Hot or Fire Orange for body/Brown for head
Under Body: Orange thread
Markings:  Black marker on thread before wrapping floss
Abdomen: Yellow floss spiraled up hook shank allowing the underbody to show
Thorax: Brown thread
Legs:  Squirrel dubbing

Tying Instructions:

  • Cover the hook shank with orange thread wrapping down the bend of the hook, building up a thicker area over the barb of the hook.  
  • Tie in a piece of yellow floss at the bend of the hook and advance the thread to the eye, whip finish and cut off.
  • Attach brown thread at the hook eye
  • Dot the back of the fly with a black marker a few times
  • Advance the floss towards the eye in open spirals allowing the orange underbody to show through and tie off at the hook eye.
  • Dub a small about of squirrel fur on thread and create the flies legs by making several wraps, pulling the fibers down after each wrap
  • Create a neat thread head, whip finish and cut off thread.
  • Apply a small drop of clear cure goo to the top of the thorax and cure with a UV light to keep the fibers pointing downward
Once this pattern gets wet the colors will change closely resembling that of the natural insect.
