Bugs, alternatively called insects, represented a class within the broader arthropods group. Examples of insect species included the can-cell, the Thunian wart-hornet, the rot-wing, the Vashkan apidactyl, and the Vespid. A defining trait was their segmented body structure, accompanied by six limbs. Additional characteristics could involve wings, compound eyes and proboscises. Certain some insects, at the very least, sustained themselves by consuming the watery fluids that circulate within plants.
The Gelagrub found on Felucia was the largest insect present in the galaxy. Certain insect species were capable of biting or stinging when provoked, employing these actions as a form of self-defense. These bites or stings could range from simple irritations to potentially lethal consequences. Like all living things, insects were connected to the Force.
Creatures sharing characteristics with insects were often described as "insectoid," "insect-like," or "insectile." Examples of such species included the Geonosians, Culisetto, the Melitto, lyleks, and gutkurrs.
