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.
10.
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
12.
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
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
