Direct pinning. Direct pinning is the insertion of an entomological pin directly through the thorax of a specimen. The insects are pinned vertically through the thorax with a suitably sized pin, but by convention they are not pinned on the midline, but to the right, so as to leave at least one side undamaged. Point. A point is a triangular piece of white card. Specially designed point punches permit the production of large numbers of points of standard sizes as required. To use a point, a pin is inserted through the broad base of the triangle. To mount the specimen, a tiny amount of glue is placed on the tip and applied to the right side of the insect's thorax. If appropriate the tip of the point may be bent at the necessary angle to hold the body of the specimen horizontal when the pin is vertical, with the long axis of the insect at right angles to the point.
Minuten pins. Insect pins without heads, 12mm long. They are used for double mounting (staging) very small insects. They also may be used profitably for staging insects of moderate size, where they have the advantage of being less damaging to the specimen. For best effect in that respect, the pin is inserted from below through the staging card, well into the thorax, but not all the way through. Alternatively the minuten pin can be inserted laterally into one side of the thorax, again preferably not all the way through. Carding. Insects (especially Coleoptera and Hemiptera) are glued to rectangular pieces of acid free card or Bristol board providing a stage. Typical sizes are 4.5 x 11 mm;5 x 14 mm;6 x 17 mm;10 x 21 mm;13 x 30 mm. Printed lines allow uniform placement of the entomological pin. Though this is convenient, it is dubious practice at best, because it obscures features that might be necessary for taxonomic or morphological studies. In any case, at the very least the glue should be sufficiently conveniently soluble to be removed with solvents when necessary. With such considerations in mind, Canada balsam is about as good an adhesive as any.
Staging. When specimens are mounted on a smaller support which in turn is supported on a normal full-sized entomological pin, this is called staging. For example a specimen might be mounted on a minuten pin, typically being pinned on its side (lateral pinning) or upright (direct pinning) with the minuten pin driven into a stage, a strip of suitable material such as dried plant pith or plastic foam supported in a horizontal position on the main entomological pin; as a rule a number 3 pin is convenient. Other forms of stage include card mounts and point mounts. The stage usually is positioned at such a distance up the vertical stage-pin, as to put the specimen at the same height as a directly pinned insect; this normally allows room for labels beneath and to allow handling of the specimen without damage. If insects are side-pinned by pins that pass right through the specimens, then the minuten should be at such an angle that different features are damaged on the opposite sides of the thorax. Competent staging protects small specimens and displays most features conveniently. The stage-pin then is easy to manipulate when moving the specimen and the stage absorbs vibrations.
== In popular culture == Pokémon creator Satoshi Tajiri's childhood hobby of insect collecting is the inspiration behind the popular video game series. A beetle collection becomes a source of fascination for a mentally disturbed woman in Chapter XI of MacKinlay Kantor's Pulitzer Prize-winning novel Andersonville (1955).
