Points to appreciate:
  • Observe the finely segemented antennae of the beetle. If you count the segments, you will find there are 11 of them.
  • Also notice the vertical ridge running down the center of the lower body segment. The hard shell-like covering is a actually modified forewings called elytra. In some insects it acts as a protection for the hindwings while in some cases the elytra are fused together and the insect becomes flightless.

  • Eyes notched by a frontal ridge.
