Update #1

BSF larvae w/i growth chambers, w/i separate containers
taped coffee filters over ventilation holes



  • Larvae were kept at 23C, 48% humidity but more ideal conditions are ~28C w/ 75% humidity.


  • The medium sized larvae fared the best. They appear to be maturing well- approx. 1/4 have turned a darker brown colour, a sign that they are maturing.


  • The xs larvae fared the worst; only ~1/3 survived and they are quite lethargic. I don't think they survived the transport/shipping process well. They seem to be more fragile than their s and m-sized brethren.


  • Found out (from Rylo) that BSF are skilled escape artists so I taped coffee filters over the (5) drainage holes in each container. This will be a temporary measure; I plan to replace the coffee filters w/ a very fine mesh on my next visit.


  • Moved BSF to a growth chamber set at 27C (with a range of 10C) and 75% humidity. Dr. A and I had trouble with the humidity setting- it appears to be broken. We placed 4 large pans of water in the growth chamber to increase humidity.
