Example of four-strap setting, traditional method for setting a moth for scientific study and display 插畫檔

The "Four-Strap" Method: This technique uses four strips of paper (the "straps") to hold the wings in a flat, symmetrical position while the specimen dries.Pinning Technique:A central pin is placed through the thorax (the middle section of the body).Additional pins are placed through the paper straps—not through the wings themselves—to avoid damaging the delicate wing scales.Small "brace pins" are often used near the antennae or abdomen to hold them in the correct position until they stiffen.Purpose: Spreading the wings is essential for identification, as it allows researchers to see the patterns, venation, and colors on both the forewings and hindwings.
