Coccinellidae Coccinellidae Coccinellidae () is a widespread family of small beetles ranging in size from 0.8 to 18 mm (0.03 to 0.71 inches). The family is commonly known as ladybugs in North America, and ladybirds in Britain and other parts of the English-speaking world. Entomologists widely prefer the names ladybird beetles or lady beetles as these insects are not classified as true bugs. The majority of coccinellid species are generally considered useful insects, because many species prey on herbivorous homopterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect
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
