Sexual Wing Shape Dimorphism in Piophila casei (Linnaeus, 1758 Diptera: Piophilidae)

The Piophilidae are synanthropic flies that grow and develop on cheese, fish, cured meat, among others substrates. Some species represents an important forensic indicator associated to carcasses, because the adults are common during the bloat stage, and the larvae are associated to the advanced to d...

In the cross-validation DA, 82% specimens were correctly classified into females and 88% males.

description The Piophilidae are synanthropic flies that grow and develop on cheese, fish, cured meat, among others substrates.
