What are the differences between butterflies and spiders?

Butterflies are insects belonging to the order Lepidoptera, characterized by their wings covered in scales, a complete metamorphosis life cycle, and a diet primarily consisting of nectar. In contrast, Spiders are arachnids from the order Araneae, possessing eight legs, fangs for injecting venom, and no wings. While butterflies undergo a four-stage life cycle (egg, larva, pupa, adult), spiders develop from eggs to juvenile forms, skipping a pupal stage. Additionally, butterflies are primarily herbivorous, while spiders are carnivorous, preying on insects and other small animals.
