Mounted Insects[edit]


  • Point.A point is a triangular piece of white card cut with a point punch. A pin is inserted through the broad base of the triangle and the tip is bent with forceps at a right angle. A tiny amount of glue is placed on this bent tip and this is then applied to the right side of the insects thorax . A correctly pointed specimen has the body horizontal when the pin is vertical, with the long axis of the insect at right angles to the point.

  • Entomological pins. Continental pins, so called because they are used internationally by museums and collectors are made of stainless or black enamelled steel. They are (except 7) a standard length (40mm) and differ in thickness only. The sizes are 000, 00, 0, 1, 2, 3, 4, 5, 6, 7. 000 are the thinnest size 7 is a very strong pin and longer (52mm) It is for very large beetles.The length allows for several data labels. The pins have round nylon heads or solid metal heads.
  • Minuten.Short(12mm long) insect pins without heads, used for double mounting (staging) very small insects.
  • Staging.Specimens pinned on their sides with minuten (lateral pinning) or dorsum upright (direct pinning) are pinned into a stage. A stage is a thin strip of high density foam (plastazote) supported in a horizontal position by a size 3 entomological pin .The stage is positioned half way up the vertical stage-pin, to allow room underneath for labels and to allow handling without damage.Staging side-pinned (at an angle so as different features are damaged on the two sides of the thorax) protects small specimens and displays most features. The stage-pin is easy to manipulate when moving the specimen and the stage absorbs vibrations.
