Traditionally, special insect pins (which are much thinner and sharper than standard pins) have been used to prepare insect specimens. Pins are available with both a black enamel coating and a grey stainless steel coating. The smallest insects can be needled with even thinner micro pins, which are also much shorter than a standard insect pin. Using a wooden pinning block, insect samples with labels can be pinned in a uniform manner. Instead of direct pinning, small insects can also be glued onto white glue boards, which are available in a wide range of sizes. After pinning, the specimens are documented by labelling them with collection and determination data. It is recommended to use a thicker label paper on which the information is printed by laser printer or written in pencil.
