Presentation on theme: "Happy Wednesday Ninjas!"— Presentation transcript:

1 Happy Wednesday Ninjas!
Have the following and be seated with your group when the bell rings: 1) your jars 2) pen/pencil 3) 2 laptops

2 Insect Collection Essential Question: “How do scientists identify and classify insects that are found in nature?” Standard: (8B) The student will categorize organisms using a hierarchical classification system based on similarities and differences shared among groups.

3 Identify the order of your insects
Today’s objectives: Identify the order of your insects Record the scientific name of your insects Correctly label your insects Pin your insects

4 1) Insect identification—practice your key
Isoptera Diptera Lepidoptera

5 2) Scientific Name

6 3) Location Label City State Date Collector
Labels can be printed by hand with a fine-point pen or printed on a laser or ink-jet printer. Use 4 pt type, no more than 6 lines long. Keep labels small & neat. Other information can go on a second label.

7 3) ID Label Scientific Name Common name Order
Labels can be printed by hand with a fine-point pen or printed on a laser or ink-jet printer. Use 4 pt type, no more than 6 lines long. Keep labels small & neat. Other information can go on a second label.

8 Pinning Block Use this tool to ‘space’ your fresh or relaxed insect high on the insect pin. Most of the time, your data label will fit underneath it and still be legible.

9 4) Once You Have Some Insects, You’re Almost Ready to Pin
Practice pinning on some of your larger, more common insects first---like grasshoppers, crickets, etc. Some larger beetles may have harder wing covers. Use a larger pin here; guide pin carefully to prevent punching out the legs Save smaller, delicate specimens, moths & butterflies for later

10 Insect Pins Enameled or stainless steel---on Amazon, if you WANT to buy them Available sizes---#000 to 7 #2 or #3 should work for most common larger insects; use these also for ‘pointing’ smaller, delicate insects. I have alternative pins for you to use. They will rust after a couple of years, unlike the “real” pins.

11 Pinning Insects---Caution!
Insects dry rapidly, becoming very brittle If you try to pin a dry insect---the legs will probably fall off---and worse If you cannot pin fresh specimens immediately, you will need to soften them or ‘relax them’ ASK ME BEFORE YOU PIN, IF YOU THINK THIS IS THE CASE!!

12 Relaxing chamber Clean, tightly-sealing container
Moisten paper towel with 1:1 mixture of water & rubbing alcohol; place in bottom of container Fold clean, dry paper towel to fit in container above the moist towel. Carefully place insects onto dry towel. Check flexibility of insects daily. Be patient.

13 Pin Position---to the right of center
. Beetle Pinning Example Diptera Hymenoptera Coleoptera Hemiptera For larger specimens! Orthoptera Dermaptera Lepidoptera Odonata Hemiptera

18 Pointing Small, Delicate Insects
We’ll just use a small piece of notecard Note card Point punch, note card Point in place on insect pin

19 Pointing Insects Pinning Insect Video
glue Use pinning block to pin the point first. Bend the very tip of the point down, dot with glue. Glue point to insect’s right side. Again, this works BEST if the insect is fresh or softened/’relaxed’. Use Elmer’s Glue---effective, non-toxic, water soluble This technique is used for insects too small or delicate to pin directly Pinning Insect Video

20 Spreading Board For Lepidoptera, Odonata Pin your fresh or relaxed
specimen first. Use screws on either end of board to widen or narrow slot where you will anchor your pinned insect. Get some extra pins & narrow strips of paper for next steps. See next slide…

21 Spreading Lepidoptera
4 Hold wing in place with pin through paper strip; repeat for hind wing, pushing its leading edge under trailing edge of forewing Use one extra pin to pull forewing forward w/o puncturing it. Vein on leading edge is strong enough to allow you to push wing forward Butterfly Pinning Example Multiple pins can Use extra pins anchor wings under to support paper strips abdomen, antennae Let sit several days. Remove Practice makes pins, paper, pin into perfect! display. Forewings are at right angles to axis of body

22 Housing Your Insect Collection
Protect it from: -Dermestid beetles -Other damaging insects, fungi -Too much light, heat, moisture -Handling or touching, shaking, jarring, dropping

23 Housing Your Insect Collection
Select a container with a tightly fitting lid; container must be deep enough to hold pinned specimens in a sturdy pinning surface; example below shows a temporary storage box. You can also use a shoebox or make a box.

24 Housing Your Insect Collection
Must have a tightly-fitting lid, keeping out pests that will destroy dry, brittle specimens These are commercially available boxes. Box on right is for permanent museum display or storage, if you WANT to buy a fancy box

25 These specimens are arranged by Order

26 These specimens also are arranged by Order
Labels are legible but a little long

27 Housing Your Insect Collection
While this arrangement looks nice, what happens if the alcohol vials ‘break loose’?

28 Identify the order of your insects
Today’s objectives: Identify the order of your insects Record the scientific name of your insects Correctly label your insects Pin your insects GROUP WORK CHAMPS
