●SHORT PEG RACK DESIGN- Short pegs prevent caterpillars from forming a chrysalis on the rack, which is inconvenient and unsafe. Caterpillars will crawl off rack to form chrysalis on the cage roof. Shorter pegs also make racks easier to clean. ●SECURE TUBES UPRIGHT TO KEEP CATERPILLARS from CRAWLING IN POOP: High quality floral tubes can be secured upright in our new and improved short peg rack, preventing the caterpillars from crawling in droppings. This helps keep each caterpillar and butterfly healthy as they grow. ●MORE WATER, LESS REFILLING: The Monarch Butterfly Life FAT CAT floral water tubes are our largest water tubes, boasting an incredible 48 ml capacity. This increased size in flower water vials saves you time and energy by requiring less refilling of the plant water for both stem cuttings and leaf cuttings. ●FLAT LIDS for LESS PROBLEMS: Our butterfly water tubes come with new and improved flat lids which help to prevent water and poop from pooling on top. The flat lids on the flower water tubes are also easier to remove and put on. ●VERSATILE FLORAL TUBES for all LIFE CYCLE STAGES: The Monarch Butterfly Life flower water tubes are perfect for holding milkweed stem cuttings, leaf cuttings, and host plants for your eggs or caterpillars while also being able to be used for nectar flowers to feed adult butterflies.
