Of the same structure as BugDorm-4 series insect cages with 96 x 26 mesh Polyester netting, this BugDorm-4F series uses very fine 150 x 150 mesh Nylon netting that effectively keeps aphids, thrips, and parasitic wasps from escaping or entering the cage.
BugDorm-4F3030 insect cage is very easy to assemble by simply connecting poles with splints. The front panel of BugDorm-4F3030 insect rearing cage is of clear plastic for observing insect activity; the top and three side panels are of fine Nylon netting (150 x 150 mesh) for ventilation. There is a 18-cm sleeve opening in the front panel for addition or removal of insects and for replacement of food material. A thin strip is sewn across the ceiling from which to suspend objects such as feeders.
The framework of BugDorm-4F3030 insect cage is of lightweight fiberglass and constructed outside the enclosure. There are no places for insects to hide inside the cage.
