Permanently preserved in a crystal-clear, optical-grade acrylic resin block (88 × 58 × 20 mm), this authentic biological preparation presents 3 primary morphological types of real insect pupae arranged side-by-side in horizontal sequence. Prominently titled \\\"Types of Insect Pupae\\\" across the top, the specimen features sequential numerical labels (1 through 3) that systematically demonstrate the key architectural classifications of hexapod pupal stages: exarate pupa with free appendages clearly detached from the body (1, such as beetle pupa), obtect pupa with developing appendages firmly cemented and glued to the body wall within a smooth chitinous shell (2, such as butterfly\/moth chrysalis), and coarctate pupa enclosed within a hardened, barrel-shaped final larval cuticle \/ puparium (3, such as true fly puparium). Encased permanently in solid, durable acrylic, this specimen delivers 360-degree, distortion-free viewing of wing pads, developing abdominal segments, antennal cases, and cuticular sutures without delicate handling, ethanol jars, or organic decay. An indispensable hands-on learning tool for entomology courses, developmental biology lectures, STEM science classrooms, and naturalist curio collections.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWHY YOU'LL LOVE IT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eAuthentic Comparative Entomology Specimen\u003c\/strong\u003e – Preserves 3 genuine insect pupae demonstrating the primary structural categories of insect metamorphosis.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003e3 Numbered Morphological Types\u003c\/strong\u003e – Sequential labels (1–3) guide clear identification and classroom study of exarate, obtect, and coarctate pupal forms.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eClear Structural Metamorphic Details\u003c\/strong\u003e – Provides crisp, magnified observation of developing limb sheaths, wing buds, segmentation, and puparium walls.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eOptical-Grade Acrylic Monolith\u003c\/strong\u003e – Solid 88 × 58 × 20 mm transparent resin block enables complete 360-degree study from every angle.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003ePermanent, Clean \u0026amp; Odorless\u003c\/strong\u003e – Durable acrylic casing seals the delicate developmental stages forever, eliminating pin fragility and chemical odors.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eMulti-Functional Display Piece\u003c\/strong\u003e – Serves as a tactile STEM teaching aid, conversation-starting desk paperweight, and unique scientific curiosity.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eEssential Invertebrate Biology Resource\u003c\/strong\u003e – An ideal hands-on visual aid for biology educators, entomology students, nature centers, and insect enthusiasts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003ePERFECT FOR\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEntomologists, biology educators, high school and university science labs, STEM students, nature centers, insect collectors, and distinctive natural history gift collections.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e E1602\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecimen:\u003c\/strong\u003e 3 Types of Real Insect Pupae (Insecta \/ Arthropoda)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Optical-Grade Acrylic Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 88 × 58 × 20 mm (approx. 3.5 × 2.3 × 0.8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Crystal Clear with Natural Specimens\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Horizontal Rectangular Block with Numbered Labels (1–3)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003e*Notice: Price is for retail.
