Bark beetles and ambrosia beetles form a large group of small wood-boring beetles that bore into trees, shrubs and vines in all forest and shrub habitats throughout the world, from deserts to rain forests. A wide variety of hosts are used. The best known species are destructive pests of coniferous forests, especially in the Northern Hemisphere. Other species may be pests of ornamental, fruit, and forest trees. Most species are not considered economically important. The group is very diverse in terms of life cycles, host plants interactions and behavior.
This site is dedicated to the bark and ambrosia beetles of the New World. Information presented here is based on a database that includes 57,256 collection records for 7,685 species. At present, information on species from the U.S., Canada, and Mexico is essentially complete. Information on species from Central America is approximately 85% complete. Host and distribution records are taken from 297 articles, monographs, and other databases. Numerous unpublished records are also included. At present this information is accessible via expandible checklists for:
Through the checklists and indices, information on synonyms, host plants, distribution, images, and distribution maps for individual species is available. Checklists for individual states and Central American countries will be added in the near future.
Image Library. An image library includes 7,458 photographs and line drawings for 1,502 species from North, Central, and South America. These come from a wide variety of published and unpublished sources. Additional images from others are welcomed. Please contact me for details.
Almost by definition, this site and associated pages will always be a work in progress. Once the information is posted, I can't control how viewers use it. I would strongly suggest that the information not be quoted without contacting me. The posted information may not be the most current. Feel free to contact me with questions, comments, and suggestions. Inevitably in a project of this size there will be errors of all sorts, so let me know if you come across any. In the relatively near future I expect to start adding more information biology and habits.
