How to Preserve Insects

Liquid Preservation

• 1

  Wash glass vials and their lids in warm soapy water and dry with a soft cloth. Fill each vial 2/3 full with 70% isopropyl alcohol.

• 2

  Place one live soft-bodied insect or larvae into the alcohol in each vial. Handle the insects carefully when placing them in the jar to avoid damaging or crushing them. Add additional alcohol to each vial to bring the level of the liquid to the bottom ring. Screw a lid tightly onto each vial to seal.

• 3

  Write the name of each insect on a piece of masking tape with a permanent marker. Stick the label to the lid or bottom of the jar.

Pin Board Preservation

• 4

  Set a wide-mouth quart sized glass jar on a flat surface. Fill the bottom of the jar with cotton balls. Pour fingernail polish remover into the bottom of the jar over the cotton balls. Let the jar sit until the cotton balls soak up the liquid. There should be no extra liquid in the bottom of the jar.

• 5

  Cut a circle from a piece of cardboard small enough to fit inside the jar. Place the cardboard circle in the jar on top of the damp cotton balls. Place the lid on the jar and screw on tightly to seal. Wrap the bottom portion of the jar in masking tape to block the sunlight from reaching the cotton balls and causing the liquid to evaporate and become less potent.

• 6

  Unscrew the jar's lid and place a large insect such as a beetle, fly, butterfly or moth in the jar. Screw the lid back on and let the jar sit until the insect dies. Place one specimen at a time in the jar.

• 7

  Set a 1- to 2-inch thick Styrofoam rectangle on a flat surface. Unscrew the lid of the jar and use forceps to remove the dead insect from the jar. Position the insect on the desired spot on the surface of the foam. Spread the wings, legs and antennas of the insect into a natural position. Insert insect pins through the tips of the wings and center of the thorax to secure the insect to the foam.

• 8

  Write each insect's name on a strip of paper with a permanent marker. Pin the paper label to the board below the specimen. Place your completed mounted collection inside a shadow box. Display the shadow box on a shelf or mantel, or hang it on a wall.
