Mantis egg cases, or oothecae, are marvels of nature, each holding the potential for 50–200 tiny predators. The DIY Mantis Ootheca Display Case lets you create a decorative, humidity-controlled showcase to protect and observe these delicate structures, doubling as an educational and conservation tool. Designed for DiscoverMantises.com, this project is perfect for enthusiasts, educators, and conservationists eager to highlight species like the Carolina mantis (Stagmomantis carolina) or Chinese mantis (Tenodera sinensis). Inspired by your passion for innovative mantis projects (e.g., DIY Mantis Sensory Maze), this guide blends aesthetics, science, and engagement to celebrate the mantis life cycle.

Why a Mantis Ootheca Display Case Matters
Oothecae are the starting point of the mantis life cycle, encasing eggs that hatch into 50–200 nymphs in spring (Prete, 1999). Unlike incubators focused solely on hatching, this display case prioritizes aesthetics and education, allowing safe observation of oothecae structure or hatching events while maintaining 50–60% humidity to prevent desiccation (Wieland, 2017). A 2020 study emphasized ethical sourcing of oothecae to protect native species, making this project a conservation tool (Brandywine Conservancy, 2020). Educators can use it to teach insect reproduction, while hobbyists can share hatching videos on r/mantids, boosting engagement. The case also highlights the ecological role of mantises, which save $1.5 billion annually in pest control (Hurd, 1999).
Fun fact: A single ootheca can produce enough nymphs to control garden pests for a season, making this display a window into their impact (Prete, 1999)!
Materials Needed
- Small Wooden Box: 8x8x4 inches, untreated wood for a natural look (available at craft stores).
- Clear Acrylic Lid: 8×8 inches, 0.1-inch thick, with ventilation holes (1 mm).
- Hygrometer: Mini digital model (~$5–10) to monitor humidity.
- Sponge: Small, clean sponge (1×1 inch) for humidity control.
- Non-Toxic Sealant: Clear, waterproof sealant to prevent mold.
- Dried Leaves: Pesticide-free leaves for natural decor.
- Velvet Lining: Soft fabric (e.g., green, brown) for aesthetic interior.
- Optional: Small fan (battery-powered, 2-inch diameter) for airflow, non-toxic glue, hinges for lid, label tags.
Cost: ~$25–45, depending on sourced materials (e.g., local leaves, recycled wood).
Time: 2–3 hours to build, plus 24 hours for sealant drying.
Step-by-Step Instructions
- Seal the Wooden Box
- Apply a thin layer of non-toxic, waterproof sealant to the interior and exterior of the wooden box to prevent mold and ensure durability.
- Use a brush for even coverage; let dry for 24 hours in a well-ventilated area to eliminate fumes.
- Ensure the box is clean and free of splinters before proceeding (Wieland, 2017).
- Line the Interior
- Cut velvet fabric to fit the box’s interior base and walls; secure with non-toxic glue for a soft, aesthetic look.
- Glue 3–5 dried leaves (e.g., oak, maple) to the velvet in a natural arrangement, creating a forest-like setting for oothecae.
- Place a small sponge in one corner of the box for humidity control; ensure it’s accessible for misting (Brandywine Conservancy, 2020).
- Install Humidity Control
- Attach a mini hygrometer to the box’s interior wall with non-toxic glue or double-sided tape to monitor humidity (50–60% ideal for oothecae).
- Lightly mist the sponge with distilled water every 2–3 days to maintain humidity; avoid over-wetting to prevent mold (Wieland, 2017).
- Check the hygrometer daily to ensure stable conditions, especially during hatching season (spring).
- Add Oothecae and Lid
- Place 1–2 ethically sourced oothecae (e.g., from native species like Stagmomantis carolina) on the dried leaves; secure with a dab of non-toxic glue if needed to prevent movement.
- Label each ootheca with a small tag noting species and collection date for educational purposes; use non-toxic ink.
- Attach the acrylic lid with hinges for easy access, ensuring ventilation holes (1 mm) allow airflow while preventing escapes (Prete, 1999).
- Display and Maintain
- Place the display case in a cool, shaded area (20–25°C) away from direct sunlight to avoid overheating or drying out oothecae.
- If hatching (spring), add a small, battery-powered fan for gentle airflow to support nymph emergence; remove after hatching.
- Clean the case monthly with mild soap and water; share hatching videos or photos on DiscoverMantises.com or iNaturalist with #MantisOotheca to support citizen science (The Mantis Menagerie, 2023).

Tips for Success
- Source Oothecae Ethically: Purchase from reputable suppliers or collect locally with permission, avoiding non-native species to protect ecosystems (Brandywine Conservancy, 2020).
- Monitor Humidity Closely: Keep humidity at 50–60% to prevent oothecae from drying out; replace the sponge monthly to avoid mold (Wieland, 2017).
- Label for Education: Include species names and hatching timelines on tags to engage viewers, especially in classrooms or displays.
- Avoid Disturbance During Hatching: Limit handling in spring to ensure nymphs emerge safely; record hatching for r/mantids posts (Prete, 1999).
- Conservation Tie-In: Document ootheca origins and hatching success on iNaturalist to contribute to native mantis research (The Mantis Menagerie, 2023).
A r/mantids user shared, “My ootheca display is a conversation starter—everyone loves seeing the eggs up close!” (Reddit, 2024).
