Slide the bag over the leaves. Tie shut with attached strings. This insect rearing bag of fine Nylon netting (104 x 94 mesh/square inch) is an economical solution for studying insects in-situ and for restricting target insects to a small area.
NOTE: Bags are sewn with single stitches. Distance between stitches is about 4 mm. Therefore, these bags may not be suitable for rearing very small insects.
