Bark and Ambrosia Beetles of the U.S. and Canada: Overview


There are 571 species of bark and ambrosia beetles known from the U.S. and Canada (Curculionidae: Scolytinae and Platypodinae). Of this total 60 have been introduced from other continents, many in recent years. Wood's Monograph of the bark and ambrosia beetles of North America (1982) has been the benchmark used for this group (Scolytinae) although it is rapidly becoming out of date. The 7 species of Platypodinae have not been treated for the U.S. and Canada in nearly 100 years. Wood included 513 species of Scolytinae in 1982. Since that time 51 species have been added to the fauna due to new introductions, newly described species, and new detections of naturally occurring species in southern Florida, Texas and Arizona (in addition to exotic species). There have also been numerous changes in generic assignments.

Wood and Bright (1992) published a World catalog that included many updates to Wood's monograph. Bright and Skidmore (1997, 2002) have published supplements to the catalog. Even so, it has become very difficult, even for specialists, to keep track of the current species and their nomenclature.

Objectives and Features

This interactive catalog and atlas includes all published data on distribution, hosts, and synonymy for all native and exotic species. Complete information on distribution, hosts, and synonymy from outside the U.S. is included for introduced species. All localities within the New World have been georeferenced and are shown on maps for each species. Localities outside the New World are listed, but not mapped.

In part, this website can be treated as a partial replacement for the World catalog and supplements for species known from the U.S. and Canada for synonymy, hosts, and distributions. It also includes other features not found in the catalogs such as images (photographs and line drawings), interactive maps, and access to the data from which these maps are drawn. On the other hand the catalog and supplements contain other information that is not included here such as details on nomenclature and references. The information shown on this website is derived from a large database which is constantly being expanded, corrected, and maintained.


These pages are still under development. At the moment this checklist is based on 2,665 distribution and/or host records. All distribution, hosts, and synonymy information is complete for Wood's (1982) monograph and taxonomic publications for the North and Central American fauna since 1982. There are still some South American data on localities, hosts, and synonyms for North American species listed in Wood (2007). This should be finished in early 2013. In November, 2012 approximately 11,000 distribution records for 287 species were added from the trap results of the USFS Early Detection-Rapid Response program from 2006-2011. In 2013 I am hoping to add photographs and or line drawings for all species found in the U.S. and Canada, include more biological and ecological information, and to extend coverage to Mexico.

Inevitably there will be errors and omissions. I would appreciate it if these are brought to my attention.

Access to Species Information

Information on individual species can be accesed through 3 routes:

Species Information

Clicking on the book icon () will bring up the species information. There are separate sections for images (if any are available), synonymy, a summary of distribution records from the database, a summary of host and trapping information from database records, a list of references from which information was taken for the species, a distribution map, and a table of data records. In the references section, links are provided to the pages in the Wood monograph and in the Wood & Bright catalog where the species is treated.
