Create a photorealistic, high-resolution model of an adult bed bug (~5mm long). Flattened oval body, segmented, reddish-brown exoskeleton. Small, broad head with prominent compound eyes, short segmented antennae, and piercing-sucking proboscis tucked under the head. Six segmented legs with tiny claws. Abdomen shows clear horizontal segmentation and expands when engorged. Use clean, neutral lighting on a smooth background. Texture: Reddish-brown glossy cuticle, darker brown on head and legs. Segments have subtle shading variation. Legs and antennae slightly translucent amber. Abdomen lighter red when engorged with blood.
