Sticking my hand right into a writhing mass of black soldier fly larvae wasn’t new, however seeing hundreds of thousands of squirming toddler bugs was. And this was only a pilot plant.
Black soldier fly larvae (Hermetia illucens) dwell in my compost. They assist break down the wide selection of natural matter that my household discards, from vegetable scraps to espresso grounds. Nonetheless, the BSFL at Innovafeed’s North American Insect Innovation Middle (NAIIC) pilot facility in Decatur, Illinois, eat a choose menu. BSFL food regimen influences the qualities of the pet meals components that they may ultimately change into. Innovafeed should guarantee constant protein and oil manufacturing earlier than constructing a full-scale fly farm.
Innovafeed partnered with the close by ADM moist corn processing facility to discover a buffet for his or her child bugs. Innovafeed and ADM are growing an industrial symbiosis to make use of byproducts from the corn processor to feed the BSFL. Innovafeed runs the world’s largest BSFL manufacturing facility in France utilizing industrial symbiosis, Sean Madison, director of North American enterprise growth at Innovafeed, instructed Petfood Business throughout a tour of the NAIIC facility. After starting operations with eggs from the French insect farm, Madison and his colleagues have now reached a degree the place they will start harvesting BSFL to extract oil and protein.
These pictures observe the lifecycle of the bugs by way of the facility.
Egg Stage (2–4 Days)
Grownup feminine black soldier flies lay clusters of 400–600 eggs in small crevices close to decaying natural matter. These eggs hatch inside a few days, initiating the larvae stage. At NAIIC, grooved boards substitute nooks and crannies close to rotting crops and animals.

Larvae Stage (14–16 Days)
The larval stage is crucial for BSFL farming. Black soldier fly larvae devour ADM’s corn byproducts, abandoning a helpful fertilizer referred to as fras. Throughout this stage, the larvae develop quickly. Likewise, their protein and fats contents enhance. Larvae are sometimes harvested after round two weeks of feeding. At NAIIC, the larvae develop on completely different moist and dry corn byproduct mixtures. NAIIC biologists are in search of an excellent recipe that can present robust development and constant excessive yields of protein and oil.
 
Pupal Stage (7–10 Days)
As soon as they cease feeding, the larvae enter the pupal stage. They type a tough shell and put together for metamorphosis into grownup flies. Throughout this stage, the dietary worth for feed manufacturing decreases, so larvae are hardly ever harvested after coming into the pupal stage. At NAIIC, larvae had been allowed to achieve the pupal stage as the ability constructed up its breeding inventory. NAIIC now has sufficient bugs to start harvesting larvae, with solely a small share going on to pupate.
Grownup Stage (5–8 Days)
Black soldier fly adults don’t feed and have a brief lifespan, targeted on copy. After rising from the pupal stage, adults mate, lay eggs, and die inside per week. The NAIIC facility has sealed chambers stuffed with hundreds of thousands of flitting black soldier flies. The flies lay their eggs on grooved boards within the rooms. The lifeless flies type drifts on the ground.Â
