Spider vs. Insect: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 19, 2023
Spiders are arachnids with 8 legs; insects are hexapods with 6 legs and 3 body segments.
Key Differences
Spiders are members of the arachnid class, distinguished by their eight legs. In contrast, insects belong to the insecta class and are recognized by their six legs. Both spiders and insects play crucial roles in the ecosystem, often acting as predators or prey.

A significant distinction between spiders and insects is their body segmentation. While spiders have two primary body segments - the cephalothorax and the abdomen, insects possess three distinct sections: the head, thorax, and abdomen. This distinction in body parts often aids in their easy identification.

In terms of habitat and behavior, both spiders and insects exhibit a wide range. However, all spiders are predators, primarily feeding on other small creatures, including insects. Insects, on the other hand, have diverse diets ranging from plant-based, like those of butterflies, to flesh-based, as seen in carnivorous beetles.

The reproductive methods of spiders and insects also vary. Spiders typically lay eggs encapsulated in silk sacs. Insects may lay eggs, but their development can encompass multiple stages, including larvae and pupa before reaching adulthood. It's interesting to note that while both groups can produce silk, spiders excel in this ability, using it for various purposes like web-making and egg protection.

While many insects can fly thanks to their wings, no spiders possess this ability. Instead, some young spiders can 'balloon', using silk threads to be carried by the wind for dispersal. This method, however, doesn't equate to the controlled flight exhibited by insects.
