In zoology, the formation of a scientific name for an organism follows a strict set of rules adopted by The International Commission on Zoological Nomenclature. This International Code of Zoological Nomenclature serves to promote the stability, accuracy, and universality of an organism's scientific name. Every proposed scientific name must be unique and distinct from all other names. In this way, every named organism is a distinguishable entity. However, scientific names are not always stable. Rules regulating dates of priority, formation of names and the use of Latin for forming names are some of the reasons that scientific names may change. To add to this confusion, taxonomic studies could dictate that an organism be reassigned to a different taxon, resulting in a change in its scientific name.
In contrast, common names of organisms, while not governed by such strict rules, remain more stable than the scientific names. However, the lack of standardization in common names, which often originate from repeated usage by workers in a particular area, may result in one organism being known by several different common names. Halysidota tessellaris J.E. Smith, for example, is known as the checkered tussock moth in the UK and as the pale tussock moth in the USA and Canada. Similarly, Acarus siro Linnaeus is called the flour mite in Australia and the grain mite in the USA and Canada.
The importance of correctly identifying an organism to a non-scientific community, as well as to fellow researchers, made it apparent that a standardized common name would allow everyone to know what organism was being discussed in a particular locality. In response, several countries adopted lists of authorized common names for those organisms most commonly found in that country, including insects. The need for a common name list for insects became apparent in the United States early in the twentieth century.
In 1903, the American Association of Economic Entomologists (AAEE) formed a Committee on Nomenclature to assure the uniformity of names of common insects; and in 1908, the AAEE published its first list, Common Names of Insects Approved for General Use by American Association of Economic Entomologists. It contained 142 common names. The current revised list of common names of insects and related organisms supersedes all earlier lists published since 1908. The list has grown exponentially throughout its existence. In 1925, 541 names appeared on the list; in 1927, another 42 names were added as a supplement. In 1931, the list had grown to 874 common names, with the addition of another 22 supplemental names. Concomitantly, the Entomological Society of America (ESA) established a Standing Committee on Nomenclature in 1907. At its annual meeting in 1935, the AAEE changed the name of the Committee on Nomenclature to the Committee on Common Names of Insects. In 1940, a list of 1108 common names approved by the joint committees of the AAEE and ESA was published. In 1950, 1294 names appeared on the list. In 1953, the AAEE merged with the ESA, and the increase in the size of the common names list continued. In 1970, another 299 names were added; and in 1978 the list was computerized by ESA Headquarters. At the same time, the name of the list was changed to Common Names of Insects and Related Organisms to reflect the other arthropods and invertebrates included in the list. The edition published in 1989 contained 2,018 names. The final printed edition, published in 1997, added another 28 names to the list. This new online version has another 46 names added since 1997. From now on, new names will be added to the online database as they are recommended by the committee and approved by the Governing Board. For a comprehensive history of the common names of insects, see Chapin, 1989 (Bull. Entomol. Soc. Am., 35(3):177-180).
The authority of the Standing Committee on Common Names of Insects, including its duties, methods of election to this committee, composition of this committee, term of office of its committee members and its operation is derived from the ESA Bylaws, Article XI, Section 11. The Committee on Common Names of Insects consists of nine At-Large members who serve three-year terms of office. The purpose of the Committee shall be to review proposals for common names and recommend names to be used in publications of The Society for approval by the Governing Board.
Authors of manuscripts submitted for publication in ESA publications may use only ESA-approved common names. These publications are the Annals of the Entomological Society of America, Environmental Entomology, Journal of Economic Entomology, Journal of Medical Entomology, Journal of Integrated Pest Management, Arthropod Management Tests, American Entomologist, and the various Thomas Say publications.
The Common Name Proposal Form for submitting potential common names is available online. The following set of rules has been established to guide an individual in the selection and formation of a common name:
1. Included species, in most cases, will inhabit the United States, Canada, or their possessions and territories. In special cases, other species may be added.
2. The list of common names is intended to include those insects and other invertebrates commonly of concern or interest to entomologists because of their economic or medical importance, striking appearance, abundant occurrence, or endangered status, or for any other sufficient reason.
3. A common name should consist of three words or fewer, but four are permissible if justifiable.
4. Most names have two parts, one indicating the family or group, and the other a modifier. In the case of names having two parts with one of them being a group name as given in Section IV, the group name will be a separate word when used in a sense that is systematically correct, as in "house fly" and "bed bug." If the group name is not systematically correct, it must be combined into a single word with a modifier, as in "citrus whitefly" and "citrus mealybug." The modifying part of the name should be based on some outstanding characteristic of the organism itself, its damage, host, or distribution.
Past convention for common names has generally favored use of contracted forms when two modifying words are used, as in “redfaced” or “broadnosed.” Submissions are now encouraged to consider use of hyphenation between modifying words if the meaning is otherwise obscure, as in "poplar-and-willow borer" and "acute-angled fungus beetle." Hyphenation is also appropriate when the proposed name includes a term that is normally hyphenated, such as "mile-a-minute weevil."
5. The use of parts of the scientific name in the common name is undesirable unless the words involved are well documented by usage as a common name.
6. Nongeographic, proper names will be in the nominative case.
7. Only in special cases should a species have more than one common name.
8. In petitions regarding taxa warranting special concern in both the larval and adult stage, the preferable name should be one suggested by the appearance or habits of the more important or better-known stage, or the one for which usage has become more established.
9. In all petitions for the adoption of new common names or changes in those previously established, the fullest consideration should be given to past usage and probable future usage. When practical, the opinions of entomologists experienced with the taxa concerned should be obtained before names are proposed. Members who wish to recommend new names or changes in existing names should accept the responsibility for making the necessary investigation. All available documented evidence, both for and against, concerning the need for each proposed name should accompany the petition when submitted.
Proposals for consideration by the committee should be submitted via the online form:
1. Online proposals are sent to ESA headquarters and then forwarded to the Committee Chair.
2. Upon receipt of a proper proposal, the Committee Chair shall forward copies of the proposal to each member of the Committee.
3. Each Committee member shall review the submitted materials and vote for or against the proposal. Votes should be returned to the Chair within two weeks of receipt.
4. The Committee Chair shall tabulate the vote of the Committee. For a proposal to be forwarded to the membership for comment, at least 7 of the 9 Committee members must vote in favor of the proposal.
5. A rejected proposal shall be returned to the submitter along with a summary of any comments by Committee members.
6. Proposals approved by the Committee shall be forwarded to ESA headquarters for distribution to the ESA membership. The comment period shall extend for 30 days after publication. Any ESA member disapproving a proposed common name is requested to submit objections and evidence opposing the proposal to the Committee Chair in the 30-day period after publication.
7. If substantial objections to the proposal are received by the Chair, the entire Committee shall reconsider the case and make a final decision. At least 7 of the 9 members of the Committee must vote to override the objection.
8. Recommended names are submitted by the Committee to the Governing Board for final adoption. Final adoption is by majority vote of the Governing Board.
9. Notice of final approval or rejection shall be distributed to ESA members.
10. A summary of adopted common names shall be distributed to ESA members.
In the event that a common name proposal is rejected, either by the Committee or by the general membership, and the author wishes to resubmit his proposal, specific procedures are to be followed:
1. The submitter must resubmit the proposal to the Common Names Committee using the standard form and must address the written comments separately. The proposal will be treated as an original proposal.
2. If the reason for the original rejection was other than not completing the proposal forms correctly, then the submitter should address the specific reasons for rejection, i.e., the insect is not economically important, the common name is being used for another insect, the proposed common name is misspelled, the scientific name is misspelled, the insect's distribution is outside of the designed area of acceptance, or the common name is composed incorrectly.
3. The Executive Committee of the Governing Board will serve as a neutral final arbiter in the appeals process.
