For the fossil trilobite (sometimes called "Dudley Bug"), see Calymene blumenbachii.
The Dudly (also known as the Dudly Bug) was an American Brass Era, gas-powered cyclecar manufactured in Menominee, Michigan, by the Dudly Tool Company from 1913 to 1915. The Dudly had an ash-wood frame, two-seater open model that was originally offered with a two-cylinder air-cooled engine. The 1914 Dudly was offered with a four-cylinder 1.6 L engine.
Approximately 100 Dudly Bug vehicles were manufactured.[citation needed]
