Large Foldable Insect Observation Cage

Unfolded: 40 cm width × 40 cm depth × 60 cm height. Total weight: ~320 g. Frame rods snap securely into corner hubs; mesh is heat-sealed to edges to prevent fraying. Vinyl window extends from top to bottom, edge-bound with soft PVC trim to protect against sharp corners. This design prioritises observational fidelity and biological integrity: vertical orientation matches natural climbing behaviour; side access avoids disturbing pupae attached near the top; generous footprint reduces crowding stress during feeding and mating stages. Used successfully in over 200 UK primary schools since 2021 — feedback highlights reliability in variable indoor climates (e.g., draughty halls or sunlit windowsills), ease of cleaning between cohorts, and consistent emergence success with Painted Lady and Small Tortoiseshell species.
