However, in the scientific community, the two terms do have differentT meanings. The word bug refers to a specific subgroup of insects classified as "true bugs" which have a feeding tube instead of chewing mouthparts. Examples of true bugs are the shield and assassin bugs. So remember, all bugs may be insects, but not all insects are bugs.
