I’m Leaving You Herbert and I’m Taking the Grubs With Me! (Or Garbage In, Pure Food Out)

Personal Reflection: One of Gerald’s obsessions for a while was Black Soldier fly larvae as beneficial insects. He bought an expensive contraption to raise his own.

But when it became necessary to clean up his old place, the thing was accidentally pitched into the dumpster by someone who thought it was a potty chair.

In this fictional letter from Karl to George, Gerald raves about what he was learning at one point.


Dear George,

I am so excited about an insect that God created I can’t stop talking about it, or them! Imagine a bug that can’t bite or sting you, does not want to invade your home, but only lives to eat every kind of garbage and manure and produces perfect food for poultry, fish, frogs, and many pets!

The adults live only a few days, mate in flight and lay about 500 eggs that hatch into larvae that do the above. But, you may say, “Who wants to harvest garbage or manure-eating larvae?” Yuck! Here comes the neat part, they self harvest!

The mature larvae have the rare ability to climb out of their feeding bins when they are of size. They climb a ramp you provide, to seek a place to pupate. At the top of the ramp they drop off into a container or onto the ground for waiting chickens (say) to eat. There are videos showing hens waiting for them and gobbling them up. The larvae are really nutritious too, high in calcium, good for egg laying birds.

Who are these insects? They are Black Soldier Flies and their grubs are sold under various names, such as Phoenix worms, Soldier Worms or BSFL. Many are raised to feed pet lizards and fish.

Universities are writing them up big time. A friend found them written up under the title “Forging a New Food Chain.” We were thinking of self sustaining food chains and here this came up!

He also showed me the most charming video of a tiny little girl feeding hens from a container of grubs. She said “This will make them very happy.”

Hey, George, it makes me happy too!

About the title, Gary Larson who drew The Far Side, made a cartoon of a female bug preparing to leave her husband who was watching tv. She is carrying their grubs and a suitcase. I miss The Far Side.

Gerald Franz (1935-2014) was like a second father to me in the 27 years I knew him. Brilliant and eccentric, with a wide array of interests, he fit the definition of being gifted. He strove to shake people loose from their conventional thinking. As a Bible believing Christian, his favorite and most studied Bible subject was prophecy. Writing became a means of teaching in his later years. See more about Gerald here.
