Yummy… necrophagous larvae, or maggots, of the blowfly. The larvae of many species of fly feed on dead tissue. Is it disgusting?
Not. It is part of Nature. This is highly useful as an ecosystem service as they very effectively clean up any carrion that is missed or left over any from larger scavengers.

As far as I know maggot (blowfly larvae) is widely used - here around it is quite common - as bait for fishing. Mostly for bream or carp.
I wondered if I can use this larvae in fly fishing or nymph fishing.

The first question was if it is natural food of fishes. Looking after information about life and habits of blowfly, I can easily imagine situations where blowfly larvae can fall in water from carrion. Some possible cases: nest between branches of a riverside tree/bush with dead nestlings, or drowned wild animals stuck between branches after a flood.

So the answer was yes, it is natural food of fishes. I guess it isn't as common food as stone-fly nymphs or such, but it is definitely an easy energy source for them if a mentioned case happen.

So lets try to tie it.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials Needed

See picture:
- Size #14 scud type hook
- Lead foil
- UNI-Thread 3/0, White (I used previously UNI-Strech thread, both are good)
- Black and yellow permanent markers (waterproof ones)
- Clear nail polish or UV resin
- Fly tying vice and bobbin

Step 2: First Steps

Make a thread base.
Cut a small stripe of lead foil.
Wrap it on hook.
Cover/fix it with thread.

Optional: secure it with super glue.

Step 3: Forming the Body

I use the thread itself for forming the body.
I still have aversions to "waste" it like this, but I tried in vain to replace with something else.

So form its body with pointed taper at its tail, and blunter taper at its head. Do not make the final form, leave it a bit slim at first.
Finish at its tail.
Color it with yellow marker all over.

Now the trick comes: start cover slightly the yellow body with thread towards its head. Make some "ribs" as sections, where yellow is covered better.
Whip finish at the head.

Another trick: rub your finger on a dirty surface (side of shoe will do it) and touch/gently rub the back of the fly. It gives another color and contrast to the "ribs".

Step 4: Final Touches

Color its head with black marker.
Cover the whole body with clear nail polish or UV resin (cure it).
When it hardens clean the hook eye and ... go fishing. Take your kids with you..

I hope this fly brings you some happy moments and you can catch a lot of fishes with it.

    Nice! I have made these with small strips of latex cut from medical examination gloves. Will try this one later!

    That's a nice fly. I had the same idea, but I used a rubber band for the body

    Sure you can. On the other hand I try to avoid all household materials, which are scented/flavoured, as they easily spook off the fishes when they touch it. If you find/have a natural one, try it.

    Thanks for this great instructable on blowfly Larvae. I have been looking for a black soldier fly larvae fishing fly. Just a slight different color in the two. Great job...!

    The maggots are used for a few types of fish where I live, and usually, we keep the container in the bait fridge for a long while. Some family members are still not keen on that idea. The horrible part of using live maggots is that someone usually knocks the tin over in the boat or on the jetty. Second to that is the fact that they are fiddly get onto a hook, especially with cold fingers. One should not eat finger food wilst using them either. Your little maggots should live long and useful lives already baited up, so I made your post my fave for the day. :-)

    This is so gross - that was my first thought because it looks so real, then I saw that you had made it - well done!
