Insert pin through body right side of center and pin specimen onto balsa wood or foam block. Position each leg and anchor it in place using cross pin technique. Arrange jaws and all other parts and antennae the same way. Remove all pins very carefully but leave pin in body if you intend to pin it in a case. Breaks repair easy with clear or Elmers glue.
Beetles have wings.
To spread them, lift each side of the shell cover like a hood of a car and pull the wing out and pin in place. This is recommended especially for large and robust bodied species. Beetles can float in a bowl of very hot water for a few to several minutes and this allows all parts to become almost immediately flexible. However, some beetles may slightly discolor.
