Capitalization of Common Names
The 1997 version of Common Names of Insects and Related Organisms, published by the Entomological Society of America (ESA), contains only 9 spider species. Two of those are placed in the wrong family and four are unrecognized common names. The inadequate coverage of arachnids by the ICZN spurred the American Arachnological Society (AAS) to develop their own list, Common Names of Arachnids. While the ESA has no rule or guideline that addresses capitalization of common names, the AAS does. Capital letters should not be used unless 1) the name begins a sentence, then the first letter of the name should be capitalized; or 2) the common name begins with a proper name, and that proper name begins with a capital letter (place name or person’s last name). MinnesotaSeasons.com will adhere to the convention adopted by AAS.
