Natural cocoon using leaves and cotton-like material. Pupa growing inside. - Materials: Leaves and cotton-like substance - Uses: For insect breeding, materials for science projects, materials, cocoons - Features: Insect observation, cotton-like cocoon, pale yellow, mature insects will lay eggs - Length: 3 cm - Thickness: 1.5 cm (Measurements are approximate for cocoon size) * Found in nature 12 hours ago. As it is a natural product, absolute perfection cannot be guaranteed. I am an amateur, so I do not know the species, when the cocoon will break, or how many eggs will be laid. I am looking forward to transactions with those who understand this and can enjoy observation and breeding. * I think it would also be good for science projects. Please consider it. * For shipping, I will include a few fresh mulberry leaves just in case. Inquiries are welcome. # #Cocoon #Silk #ScienceProject #Insect #InsectBreeding #MulberryLeaves #Silkworm #kikibotanicgarden 2506-①
