This insect cage category includes 4E, 4F, flekci, acrylic, and field cages—each tailored for specific research and rearing needs. 4E and 4F cages feature aluminum pole frames with Eco Mesh (600 micron) or Fine Mesh (100–200 micron), available in all-mesh (M) or clear-panel (MC) options. flekci cages use sturdy aluminum profile frames for added strength and modularity. Acrylic cages offer clear, rigid panels for visibility and containment, ideal for behavior studies. Field cages are portable, robust units designed for outdoor experiments. Together, these cages support a wide range of entomological applications in laboratory, semi-field, and field environments.
