Bill Gates' flower fly (Eristalis gatesi) is a flower fly endemic to Costa Rica named after Bill Gates.{{cite web |url=http://www.sel.barc.usda.gov/Diptera/syrphid/gates.htm |title=Bill Gates' Flower Fly |access-date=2008-05-24 |url-status=dead |archive-url=https://web.archive.org/web/20080212030504/http://www.sel.barc.usda.gov/Diptera/syrphid/gates.htm |archive-date=2008-02-12 }} Another fly found in similar habitats was named after Gates' associate Paul Allen, called Paul Allen's flower fly (Eristalis alleni); according to Chris Thompson, the describer of these species, both names were in "recognition of [their] great contributions to the science of Dipterology".{{cite web |url=http://www.sel.barc.usda.gov/diptera/syrphid/allen.htm |title=Paul Allen's Flower Fly |access-date=2008-05-24 |url-status=dead |archive-url=https://web.archive.org/web/20080228231710/http://www.sel.barc.usda.gov/Diptera/syrphid/allen.htm |archive-date=2008-02-28 }}{{cite journal
