Here’s a link to the insect key to use for identifying insects: Insect Key
The insect collection project display is due Monday April 29th.
The display must consist of at least twenty insects, from at least five different orders. The may be no more than 5 insects from one order.
Insects may be pinned to the display board (for hardbodied insects, butterflies, moths), stored in a vial of ethyl alcohol (softbodied insects), or attached with nail polish to a small paper triangle which is pinned to the board (insects too small to pin directly).
Relaxing insects that have been stored in the freezer:
- If an insect has been stored in the freezer, it will need to be “relaxed” in order to spread out the body for the display.
- To relax a butterfly/moth: put in shallow dish with moist paper towel on bottom and cover overnight.
- A beetle or other hard-bodied insect: placed in glass with 50% alcohol (isopropyl alcohol is fine) and 50% water overnight.
Displaying the Insects
·Hard bodied insects: All hard bodied insects should be pinned to a foam board, and an information card should be pinned next to it.
- Insects are generally pinned through the thorax (the middle section of the body), slightly to the right of the midline, in the region where the second pair of legs are attached.
Soft bodied insects: All soft bodied insect should be preserved in a jar or vial with 70% alcohol. A label should be attached to the jar with the required information.
Insects too small to pin:
- First cut out a small triangle of stiff paper.
- A pin is passed through the center of the triangle, and the insect is attached onto the longest tip of the small triangle.
- Attach the insect by painting over its body with clear nail polish. Avoid painting the insect’s legs and wings if possible
Information Card- Required for each insect:
On your display, you should have the following information written on a card next to each insect:
- Place collected
- Where theinsect was found (what type of plant, in a burrow, under the litter, etc.)
- Date collected
- Name of collector
- Order name
- For more information on insect collections and insect identification, check for insect field guides at your local library, look in your biology textbook, or search online.
