Types of Insect Pupae Specimen Paperweight – Real Insect Metamorphosis in Resin

A Comparative Entomology Reference: Real Insect Pupae Metamorphosis Types in Optical Resin

Examine the fascinating developmental biology, complete metamorphosis (holometabolism), and morphological diversity of insect transformation with the Acever Types of Insect Pupae Specimen Paperweight (Model: E1602). 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.
