Scientific illustration of a beetle exoskeleton showing features for heat resistance and moisture retention with labels.

Illustration: Modified Exoskeleton Structure (Hypothetical ZOOM IN sketch description for labeling rain forest shield beetle) Key Features: Thickened Chitin Layers (brown/orange): Dense, heat-reflective layers protect against 40°C forest floor temperatures. Microscopic Heat Vents (red arrows): Pores release excess heat to prevent overheating. Waxy Coating (yellow highlights): Retains moisture in humid environments. Labeled Annotations: "Heat-resistant chitin reflects infrared radiation." "Vents regulate body temperature during peak heat." See more
