This document provides instructions for properly pinning insects for display and classification. It explains that insects should be pinned through the thorax or widest part of the body in a natural springing position. Smaller insects can be pinned using triangles cut from index cards with glue. Wings of moths and butterflies may require special mounting. The key characteristics of insects are six legs and a body divided into three sections: head, thorax, and abdomen. Students are given 25 minutes to pin collected insects or write a 500-word essay explaining their plan to prepare for future pinning assignments. Directions are provided for classifying insects using taxonomic keys, determining the order, locating common and scientific names in reference books.
