The insect rearing sleeves are manufactured from fine Nylon netting (100 x 80 mesh). The sleeves solve problems of studying insects in-situ. Each sleeve has a large clear window for observation, one full-length zipper that allows the sleeve to open flat, and long strings for sealing the ends around branches. Sleeves of the same size may be zipped together to gain diameters required to enclose sections of tree trunks.
