Venus fly trap simulator
A small plant. An extraordinary life. An interactive way to explore both.
Make hidden plant science visible
This free, browser-based 3D simulator invites you to explore Dionaea muscipula, the Venus flytrap. The project’s goal is to turn curiosity about carnivorous plants into hands-on learning: select a trap, offer an insect, and follow a meal from capture to digestion and new growth.
The plant is the main interface. On mobile, tap a trap directly, choose a fly, ant or spider, and feed it using the controls beneath the scene. Orbit the plant or open the digestion lens for a cutaway view. No account or installation is required; your plant and field journal save in your browser.
Follow the complete hunting cycle
Explore trigger-hair stimulation, closure, sealing, enzyme activity, nutrient absorption and reopening. The cutaway shows digestive fluid and the remains of prey, helping explain why digestion is more than a snapping leaf. Older traps eventually make way for new growth.
Sunlight supplies the plant’s energy; insects supply additional nutrients. Choose an indoor windowsill with supplemental light or a seasonal garden terrace where insects can arrive naturally. Pause to inspect a stage, change the clock speed, or skip forward by two hours or one day.
False alarms and a perennial life
Use Touch twice within the signal window to explore an empty closure. The trap reopens without digesting or gaining nutrients. Closure counts include false alarms as well as meals. Worn-out traps become inactive green leaves before blackening, while the perennial plant continues through seasonal rest and spring regrowth. Open the plant lifecycle panel to skip between seasons.
Learning through observation
The project aims to make plant biology approachable, encourage experimentation, and connect a playful simulation with published research. A built-in field guide explains the science, links to research, and describes the model’s assumptions. The journal records events so you can follow your plant’s development.
A teaching model, with clear limits
This is an illustrative seasonal model, not a prediction of a real plant’s health or care needs. Water and light are held at suitable levels. Digestion times, insect visits, growth percentages, acidity and leaf lifetimes are teaching approximations. The adopted juvenile ages toward a three-year maturity target. A modeled 90-day winter slows leaf growth and pauses feeding; spring restarts replacement leaves. Both habitats represent seasonal conditions. Disease, temperature injury, seed germination, flowering and rhizome division are not interactive. Digestion and nutrient uptake overlap in real plants; separate stages make those processes easier to explore here.
