Rugose Carrion Beetle
A small, dark silphid with heavily textured, rugose wing cases. It frequents sun-exposed carrion in open landscapes.
Did You Know?
Females lay eggs on carcasses already infested with fly larvae, and their own larvae then feed on the maggots.
Secondary Screwworm Fly
A blow fly that breeds in carrion and occasionally infests wounds in livestock. It is widely used in forensic studies in the Americas.
Did You Know?
Unlike the primary screwworm, it only feeds on dead tissue rather than living flesh.
