2.  Steps of insect collection
 Equipments for pinning(description)
 Pinning of different insects(order)
 Arrangement

3. Steps of Insect collection
• Capturing by different techniques
• Killing them by the help of killing jar
• Relaxing insects
• Pinning insects
• Labeling insects
• Storing insects

4. Why pinning required
• Before displaying --posture should be maintained
• To avoid breakage
• To demonstrate each part clearly
• To make collection neat and clean

5.  “Insect Pins” for pinning
 Pinning block
 Spreading board
 Preserving or display boxes

6. Pinning of insects
Types of pins.
Height of insect on pins
Posture of insect on pin
Where to pin
Labeling etc

7. • “Insect pins” should be used to avoid rust and
to adjust the insect properly
• Insect pins come in various sizes ranging from
000 to 7
• Smaller the no…… the thinner the pin.
• Sizes 1-3 best size for most insects.

8. Height of insects
• All parts of insects should have uniform
distance from the top of the pin.
• A good distance is 8-10 mm or about 2/3 or
1/4 of the way up the pin.

9.  The use of a pinning block will help in obtaining
proper height and positioning.
 7.5 cm long and 2.5 cm wide
 The first step is 0.6 cm high, the second 1.2 cm
and the third 2.2 cm high.

11. Posture on Pins
• Legs and antennae should not be projected
into lifelike positions.
• Legs should be tucked under the insect’s body
• Antennae should be in horizontal manner

13. Smaller should be mounted on card points
Card points are slender triangles of paper.
With the help of glue attach the insect
from right side
 Soft-bodied insects such as caterpillars,
mayflies, silverfish and others cannot be
pinned.

14.  Through the right side of the
thorax with the wings spread.
 Through the left side of the
body with the wings folded

15. Order Coleoptera:
(Beetles)
• Pin through right elytra(wing)
• Do not spread the wings

16. Order Orthoptera:
Grasshoppers, katydids and crickets
 Pin through the right side
of the pronotum.
 Set only the wings on left side.

17. Pin through the right side of
thorax, a little behind the
forewings
In flies set wings with the
front edges at 45° to the
body.

18. • Pin through the V shaped
shield (scuttelum), to the
right of middle line
• Do not spread wings

19. Order Neuroptera:
antlion, lacewings,and dobsonflies
Pinned through the right
side of pronotum
First margin of rear wings
at right angle to the body

20. • Pin through right side of thorax
• Hind margin of front wing at
right angles to the body
• Rear wing arranged so only a
small notch between front and
rear wings

21. 1- place insect in the center of spreading board
2- Place two strips of papers along both wings
3- Raise forewing to adjust it perpendicularly
4- Raise hind wing to reduce notch between
two wings.
5- Support the abdomen with the help of pins by
making V shape below abdomen
