One notable large dung beetle is the "Goliath beetle" (Goliathus spp.), which is among the largest species of beetles in the world. These beetles can weigh up to 100 grams and have a wingspan of up to 25 centimeters. Found primarily in Africa, they are known for their striking coloration and impressive size.
