Distribution: Mainly distributed in the coastal regions of the eastern United States: Alabama, Connecticut, Florida, Georgia, Louisiana, Maryland, Massachusetts, Mississippi, New Jersey, North Carolina, Rhode Island, South Carolina, Tennessee, Virginia, as well as two outlier samples; one in Oklahoma and one in Iowa.
 
 
 
 
 

Remarks: Specimens of P. luctuosa are relatively easy to identify due to their large size (20-22mm), robust character, broadened posterior end, and marked convexivity. Large discrepancies between male and female size can exist in individuals collected near each other.
 
 
 
 

Biological data: Phyllophaga luctuosa is primarily found in coastal states in sandy soils and is not known to be a pest on any crops. The life cycle is typically 2-3 years.

 
 
 

Temporal distribution:Temporal distribution: Phyllophaga luctuosa adults emerge early in the spring, with some specimens in Florida collected as early as February. Usually, P. luctuosa emerges in March in the southern states and June in the northern states.
