Crabs and lobsters are arthropods. In colloquial speech the term "bug" generally refers to arthropods on land, mostly insects and arachnids. In scientific terms the only true bugs are insects in the order hemiptera, excluding crustaceans, which are not insects.
Crustaceans (Crustacea) are arthropods. At least one form of crustacean is known as a "bug." The woodlouse, more commonly known as the "pill bug" or "rollie pollie" is a crustacean. Insects are more closely related to crustaceans than they are to any other arthropods.
