South American Grain Stem Sawfly
A slender black stem sawfly with smoky wings and yellow abdominal bands. It attacks cereal grain stems in parts of Europe and Asia.
Did You Know?
Like other cephid stem borers, the larva constructs a silken cocoon inside the hollowed-out stem base where it overwinters before pupating in spring.
Broad-Horned Onitis
A large, dark brown to black tunneler with massive forelegs in males. The prothorax is greatly enlarged. It digs deep vertical shafts beneath cattle dung and is primarily nocturnal. Males use their forelegs in combat.
