Black Soldier Fly (BSF) Forums Pictures & Videos

Below are pictures highlighting Black Soldier flies (BSF) processing and recycling food scrap wastes, larvae in different stages of their life-cycle, examples of how to construct BSF Propagation Bioreactors (PBRs) out of inexpensive plastic totes, and youtube's illustrating how to manage and sustain propagation of BSF in the PBRs incuding the cycling and mixing of egg clutches and food scrap through the units.

BSF and Larvae at Varying Stages of Their Life Cycle

  1. newly born cream-colored black soldier fly larvae, emerging, feeding and crawling about in an aqueous food scrap slurry
  2. young larvae burrowing through and growing on food scrap added to a black soldier fly bioreactor (pbr)
  3. image of light-yellow egg clutches deposited by female bsf in small crevasses on the underside of bsf bioreactor lids
  4. comparative size of newborn bsfl. newborn larvae are about 1/20th the diameter of a quarter.
  1. image showing the size and appearance of tan to brown colored young bsfl growing on food scrap at about the prepupa stage in their  life cycle
  2. Image of female BSF using her ovipositor to lay her egg clutch between a BSF Propagation Bioreactor's (PBR) bin and lid

Conversion of Inexpensive Totes Into BSF Propagation Bioreactors (PBRs)

Commonly available plastic bins and totes can be easily converted into BSF Propagation Bioreactors (PBR's) as illustrated in the accompanying pictures. Adult females attracted to food waste added to the PBRs enter through holes drilled into the walls and lids of the PBRs and deposit egg clutches inside the PBRs which subsequently hatch in a matter of a few days. New larvae hatching from the egg clutches proliferate in the waste. Upon reaching the prepupae stage in their life-cycle they self-harvest from the waste through vent holes drilled through the walls of the units, pupate, re-emerge as adults, mate and return to the PBRs in sustaining their colony. PBRs can be used as a simple means of propagating and growing BSF on food scrap wastes.

BSF Consuming Fish Carcass Placed in Food Scrap Bin

  1. Image showing initial appearance of fleshy fresh remains of a tuna carcass added to a bsf food scrap bioreactor
  2. skeletal remains of tuna carcass absent fleshy parts 24 hours after presentation to bsfl

Herps Feeding on Young Larvae

  2. image of leopard gecko in attack posture peering down at a bsf larva ready to snap it up in its mouth

Using a Larval Containment Bin to Collect  Self-harvesting Prepupa Crawling Out of a Backyard BSF Bioreactor

  1. image showing how prepupae self-harvesting from a bsf bioreactor get collected in a bucket
Prepupa self-harvesting from a "BSF Food Scrap Recycler" fall by gravity into a larval containment bin (see left image "(a)", upper and lower panels)  surounding the Recycler. BSF prepupae crawl through a side hole cut in the containment bin and subsequently can be collected in a harvesting bucket (see right image "(b)", upper and lower panels) placed beneath the hole of the larval containment bin.
