Key Differences

Beetles are part of the order Coleoptera and are characterized by their hard exoskeleton and forewings modified into protective covers for their secondary wings. Whereas spiders belong to the class Arachnida and are distinguished by having eight legs and chelicerae with fangs that inject venom.
Beetles undergo complete metamorphosis, which includes stages as an egg, larva, pupa, and adult. On the other hand, spiders typically develop through a simpler process, involving several stages of molting from egg to maturity without a pupal stage.
The diet of most beetles primarily includes plant and animal materials, depending on the species. Conversely, spiders are predominantly carnivorous, usually preying on insects and sometimes small vertebrates, using their venom to subdue their prey.
Beetles typically use their wings to escape predators or to migrate, which adds to their mobility. In contrast, spiders often rely on their ability to produce silk for various purposes, including making webs to catch prey, creating shelters, or aiding in locomotion.
The sensory abilities of beetles are diverse, with some species having excellent vision or olfactory senses for detecting pheromones. Spiders, however, generally have poor vision but exceptional tactile senses, primarily through hairs on their legs that detect vibrations and air currents.
