In the third output of the project, black soldier flies were reproduced from larvae which are the research object for 4th grade students in Länsiharju. Children were very excited to meet newborn flies. It was very interesting for them to observe larvae transforming into black soldier flies because they were participating in each step of this project.

16th day of October

The children and the teacher of Länsiharju primary school grade 4B arrived at Pikkuvesijärvi lake at 9 am. By chance the day also was the UNICEF-walk day where students raise money by walking or running kilometers, so the class came to the lake by walking from the school. The day’s mission regarding the Blue Wings Composting project is to feed to the lake’s fauna the frozen black fly larva from the composting project.

The class had been feeding these larvae for 14 days and had been sad to let them go. The project introduces children to the cycle of nature and so at the end of it, larvae had to become food for other living beings. The children were divided into smaller groups and given containers of the frozen larvae which they then threw into the Lake for the ducks and fishes to eat.

The whole process went very smoothly and was over in a short while. The ducks seem to interest the children most.

After a successful finish to the project, the children continued their UNICEF-walk back to school.

Black Soldier Fly larvae – based bioconversion at Länsiharju school in Lahti was terminated according to the plan.

The bioconversion by larvae was in operation for 14 days. Larvae ate with good appetite mixed school kitchen waste food that was served to larvae once a day.

The bioconversion was managed by the teacher of Länsiharju school and 10-years old children of the class. The forthcoming bioscientists were courage and curious, and they handled and monitored larvae daily basis according to detailed guidance and data collection matrix (see pics below).

The bioconversion produced value tor four different end-user groups. The first end-user group was the teacher’s home chicken farm. As you can see on the video the chickens really enjoyed to eat fat larvae which are full of protein and oil. Healthy diet indeed – for chickens.
