How to set up your insect box
  • Organize your insects in an insect collection
    box according to the order in which they belong.
  • Each order must have a label.
  • The heads of all insects should point towards the
    top of your collection box when the short sides
    of the box are on the left and right.
  • All boxes must be covered with a clear protective
    material such as glass or plastic wrap.
  • (It is easiest to pin and place your insects on a
    piece of covered cardboard or Styrofoam and then
    to place the cardboard or Styrofoam in a
    Tupperware container, a shoe box, a wooden box,
    etc.)

Information that you need to provide for each
insect
  • On small square pieces of paper (identification
    tags) the following information needs to be
    placed
  • Tag 1 (top tag)
  • Locality of collection (town, county, state,
    etc.)
  • Date of collection
  • Name of collector
  • Tag 2 (bottom tag)
  • Common name
  • The tags need to be placed on the insect pin
    below the insect so that they can be read from
    the left-hand side.

4
How to pin your insects
  • For small or fragile adult insects
  • Glue to the point of a small triangular piece of
    rigid white paper, so that the insect pin goes
    through the center of the base of the triangle,
    the triangle points towards the left, and the
    head of the insect is towards the top of the box.

5
How to pin your insects
  • For soft bodied insects or larvae
  • Place in a vial of alcohol.
  • (Information to be placed on tags will be written
    on the outside of the vial.)

6
How to pin your insects
  • Coleoptera (beetles)
  • Pin should pass down through the right outer
    wing.

7
How to pin your insects
  • Hemiptera and Homoptera (true bugs, aphids, and
    leafhoppers)
  • Pin should pass through the triangular scutellem,
    slightly to the right.

8
How to pin your insects
  • Lepidoptera and Odonata (butterflies, moths, and
    dragonflies)
  • Pin should pass through the center of the thorax.
  • Place (and pin) narrow strips of paper over the
    wings to spread them nicely while the insect
    dries.

9
How to pin your insects
  • Orthoptera (grasshoppers)
  • Pin should pass through right of the scutellum.
  • Left wing should be pulled out and pinned with a
    strip of paper while drying.

10
How to pin your insects
  • For all other insects
  • Pin directly through the thorax a little to the
    right of the midline of the body.
  • Leave about ¼ inch of the pin visible above the
    specimen.
  • Make sure the insect is level on the pin (not
    tipped from front to back or side to side)
