Coccinellidae wide variety of beetle species in other families as "ladybirds", i.e. coccinellids. Beetles are particularly prone to such misidentification if they are spotted in red, orange or yellow and black. Examples include the much larger scarabaeid grapevine beetles and spotted species of the Chrysomelidae, Melyridae and others. Conversely, laymen may fail to identify unmarked species of Coccinellidae as "ladybirds". Other beetles that have a defensive hemispherical shape, like that of the Coccinellidae (for example the Cassidinae), also are often taken for ladybirds. A common myth, totally unfounded, is that the number of spots on the insect's back indicates its age.
Common Lisp predates CL, and comes not only from the same Lisp tradition but from some of the same engineers—Guy L. Steele, with whom Gerald Jay Sussman designed Scheme, chaired the standards committee for Common Lisp. Common Lisp is a general-purpose programming language, in contrast to Lisp variants such as Emacs Lisp and AutoLISP which are extension languages embedded in particular products (GNU Emacs and AutoCAD, respectively). Unlike many earlier Lisps, Common Lisp (like Scheme) uses lexical variable scope by default for both interpreted and compiled code. Most of the Lisp systems whose designs contributed to Common Lisp—such as ZetaLisp and Franz
