Infographie animée gratuit du cycle de métamorphose du papillon

Educational infographic poster titled "Butterfly Metamorphosis Cycle" in portrait layout, designed as a detailed educational poster with sharp, readable sans-serif text labels and clear numbered callouts. Create an isometric 3D nature/biology infographic for enthusiasts with 9 numbered stages/components, each clearly separated but linked in a continuous lifecycle flow using bold arrows, dotted transition lines, and visible sequence numbers 1-9 arranged in a circular-progress path from top to bottom and back upward. Visual style: isometric 3D biological editorial diagram, high-contrast yellow & navy palette with pale cream accents, crisp shadows, clean geometry, technical yet lively mood, magazine-grade editorial illustration, vector-clean lines, no photographic textures.

1. heading: "Egg Cluster"; caption: "Tiny eggs attach to the underside of a host plant leaf."; visual: isometric close-up of a navy leaf cutaway with several small yellow oval eggs glued along a vein, magnified inset circle showing egg texture.

2. heading: "Embryo Development"; caption: "Inside each egg, the embryo forms and prepares to hatch."; visual: transparent cutaway egg with simplified internal larva silhouette, small development timeline bar beside it, dotted micro-detail arrows from the inset back to the leaf.

3. heading: "Hatching Larva"; caption: "A caterpillar breaks the shell and emerges onto the leaf surface."; visual: one egg split open with a small caterpillar crawling out, shell fragments visible, directional arrow showing movement from egg to leaf edge.

4. heading: "Feeding Caterpillar"; caption: "The larva eats leaves rapidly to gain energy for growth."; visual: larger striped caterpillar in isometric side view chewing a leaf with bite marks, nearby leaf area diagrammed with missing sections, small energy icon and intake arrows pointing toward the body.

5. heading: "Molting Stages"; caption: "The caterpillar sheds its skin several times as it grows."; visual: sequential mini-diagram of 3 increasing caterpillar sizes in a row, each with a thin cast skin behind it, curved arrows between forms, small ruler marks indicating size increase.

6. heading: "Full-Grown Larva"; caption: "The mature caterpillar stops feeding and searches for a safe attachment point."; visual: thick-bodied caterpillar climbing a twig, head raised, silk attachment pad shown on branch tip, path arrow indicating upward movement.

7. heading: "Chrysalis Formation"; caption: "The larva hangs and transforms into a protective chrysalis."; visual: step-by-step hanging J-shape caterpillar beside a freshly formed chrysalis attached to a twig, transformation arrows and a small silk anchor detail.

8. heading: "Pupal Transformation"; caption: "Inside the chrysalis, the body reorganizes into adult structures."; visual: semi-transparent chrysalis cutaway showing folded wings, antennae, and segmented body developing inside, technical annotation lines pointing to wing case and abdomen.

9. heading: "Adult Butterfly"; caption: "The butterfly emerges, expands its wings, and begins the cycle again."; visual: newly emerged butterfly beside an opened chrysalis, wings partially unfurled in one mini-view and fully spread in another, arrow looping back toward the egg stage, small host plant and nectar flower icons to suggest reproduction and continuation.

Add a compact legend panel in one corner with exact labels: "Life Cycle Flow", "Growth", "Transformation", and "Reproduction" paired with simple arrow and icon symbols. Use navy background blocks, yellow highlights, cream text panels, and strong contrast for technical readability. Keep all labels clean, modern, sans-serif, aligned to each numbered stage, with no clutter and generous spacing. No logos, no copyrighted characters, no identifiable people, no graphic medical content. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
