==Areas of research== Otte has contributed to the following areas of research:
* Communication and signaling systems * Origins of organic diversity (speciation, colonization, etc.) * Behavioral ecology * Sexual selection * Discovery of new cricket and grasshopper species from the Pacific region, the Caribbean islands, western United States and Africa * Comprehensive systematic treatments of regional faunas (North America, Australia, Hawaii, Caribbean, southern Africa) * Developing world catalogs of grasshoppers, crickets, katydids, stick insects, mantids and cockroaches * Publicizing organic diversity via the internet (Orthoptera Species File)
==Books written for the general public== Otte also has illustrated the following books for general audiences: * ''Behavioral Guide to African Mammals'' by R. D. Estes, University of California Press. 1991 * ''The Safari Companion: A Guide to Watching African Mammals'' by R. D. Estes, Chelsea Green Publishing Co., Post Mills, VT. 1992 * ''The Birds of North America''. Alan Poole editor, American Ornithologists Union (contributing illustrator). 1992<ref>{{cite web|url=https://www.amazon.com/s?ie=UTF8&search-type=ss&index=books&field-author=Daniel+Otte&page=1|title=Amazon.com: Daniel Otte: Books|website=www.amazon.com}}</ref> * ''Limpopo River Tales'': Daniel Otte (Author, Illustrator), Carin Thom (Author) Austin (July 31, 2017)
==Species files== Otte is the founder and principal author of "Orthoptera Species File", an online catalog providing information on all the world's grasshoppers, crickets, katydids and related species. With the world's largest collection of grasshoppers and crickets and an outstanding library, the Academy of Natural Sciences pioneered in the task of placing a catalog of all known species of a major group of insects on the Internet. The Orthoptera Species File provides access to data on one of the most economically important groups, the grasshoppers, historically one of man's important competitors.
Otte is founder and senior author of the "Mantodea Species File", a catalog of the praying mantis species of the world, and is founder and principal author of "Phasmida Species File", a catalog of the stick insects of the world.
==Documenting biodiversity== Otte has conducted research which documents the magnitude and origin of organic diversity in the following regions: *North America: United States, Canada and Mexico. *Central America: the Caribbean Islands and Costa Rica. *South America: Argentina, Brazil, Ecuador and Venezuela. *Southwest Pacific area: Australia, New Zealand and Malaysia. *Pacific Islands: Galapagos, Hawaii, Fiji, Samoa and Solomons. *Africa: South Africa, Malawi, Kenya, Tanzania, Mali, Botswana, Swaziland, Lesotho, Zimbabwe and Zambia.
==Symposium and honours== A symposium was held in June 2009 to honor Otte, Curator of Entomology at the Academy of Natural Sciences in Philadelphia. It was held at the University of Lethbridge, in Lethbridge, Canada.<ref>{{cite web|url=http://www.danottesymposium.com/|title=Join Us in Honouring Dan Otte in June! - Dan Otte Symposium|website=www.danottesymposium.com|access-date=2009-01-22|archive-date=2009-04-29|archive-url=https://web.archive.org/web/20090429114838/http://www.danottesymposium.com/|url-status=dead}}</ref> Otte received the Leidy Award for scientific excellence on November 12, 2009 at the Academy, where he has worked as curator of entomology for 35 years.<ref>{{cite news |last=Avril |first=Tom |date=December 22, 2009 |title=A big man in the world of insects Entomologist has identified 1,500 species |url=http://articles.philly.com/2009-12-22/news/25270703_1_grasshoppers-crickets-foremost-experts |archive-url=https://archive.today/20150415001139/http://articles.philly.com/2009-12-22/news/25270703_1_grasshoppers-crickets-foremost-experts |url-status=dead |archive-date=April 15, 2015 |newspaper=The Philadelphia Inquirer |location=Philadelphia |access-date=April 15, 2015}}</ref>
