Physical Description and Identification


Size: 0.75 to 1.5 in (1.9 to 3.8 cm)

Color:They are shiny black, with irregular white spots.

Other Characteristic Features: The only common feature among all the beetles in this family is their long antennae, which are connected with sockets located on their face.


The larvae of these beetles, called roundheaded borers, bore into the wood of host plants.


Pupation occurs inside the tunnels excavated during the larval stage. This stage lasts for 13-24 days.


The females lay 25-40 eggs, which hatch in 1-2 weeks.
