![]() Most bugs are plant-feeders while beetles eat both plant and animal materials. Number of SpeciesĪround 75000 species of bugs have been identified so far while around 400000 species of beetles have been identified. The main difference between a bug and a beetle is that a bug belongs to the order Hemiptera while a beetle belongs to the order Coleoptera. ![]() Thus, this explains the fundamental difference between a bug and a beetle. Moreover, many of them are agricultural pests.ĭifference Between a Bug and a Beetle DefinitionĪ bug refers to any of an order (Hemiptera and especially its suborder Heteroptera) of insects (such as an assassin bug or chinch bug) that have sucking mouthparts, forewings thickened at the base, and incomplete metamorphosis and are often economic pests while a beetle refers to any of an order (Coleoptera) of insects having four wings of which the outer pair are modified into stiff elytra that protect the inner pair when at rest.Based on the species, both can fly, walk, jump, glide over the surface of the water or even swim.And, they inhabit both terrestrial and aquatic habitats.Moreover, they live all around the world.Also, both their body has a head, thorax, and abdomen.Both are types of arthropods with six jointed legs, an exoskeleton, and two pairs of wings.Bug and beetle are two types of insects that belong to different orders.But, some of them are parasitic and others are predators that prey on other insects or small invertebrates. The sucking and the piercing mouthparts allow bugs to extract plant sap and nectar. However, only heteropterans are considered as ‘ True bugs’. One of the main features of bugs is the presence of sucking mouthparts. The size of bugs varies from 1 mm- 15 cm. – Comparison of Key Differences Key Termsīeetle, Bug, Diet, Forewings, Lifecycle, Metamorphosis, Mouthparts, Orderīug – Definition, Characteristics, Behaviorīugs are a group of insects classified under the order Hemiptera. What is the Difference Between a Bug and a Beetle What are the Similarities Between Bug and BeetleĤ. Around 75000 species of bugs and 400000 species of beetles have been identified so far. Moreover, the wings of bugs are either membranous or partially-thickened while the forewings of beetles serve as a hard, leathery covering called elytra and the hindwings are membranous.īug and beetle are two groups of insects that belong to two different orders. Therefore, bugs have needle-like mouthparts while beetles have chewing mouthparts. Furthermore, bugs are mostly plant-feeders that take a liquid diet while beetles eat a wide range of plant and animal materials. The main difference between a bug and a beetle is that a bug belongs to the order Hemiptera whereas a beetle belongs to the order Coleoptera.
