Distribution: Midwest to eastern US distribution: Alabama, Arkansas, Florida, Kentucky, Indiana, Iowa, Oklahoma, Michigan, Missouri, Nebraska, Tennessee, Virginia, West Virginia.
 
 
 

Remarks: Phyllophaga hornii is among the largest of the Phyllophaga species (19-23mm), and is very dark brown in color. Although Luginbill and Painter (1953) noted that this species was constant in form, specimens collected by Woodruff and Beck (1989) in Florida as well as others collected in Ohio have a modified left male paramere with an additional carina. The specimen shown above does not have this carina and was collected in Trenton, Georgia in the northwestern corner of the state.

 
 
 
 
 
 
 
 

Biological data: This species is relatively rare and is not very prominent in most collections.

 
 

Temporal distribution: Adult emergence begins in mid-March in southern states through June in northern states.
