English: Video of a Protopulvinaria pyriformis (Hemiptera: Coccidae, pyriform scale) forming a multi-branched in āere stylet sheath. Primary and secondary segments indicate dorsal and ventral stereo micrograph images of a Protopulvinaria pyriformis (Hemiptera: Coccidae, pyriform scale) on a leaf and caged in a mock feeding chamber forming a stylet sheath (respectively). Subsequent to these, a stereoscopic video of a single scale indicates the formation of a multi-branch stylet sheath across the clear plastic wrap of the mock feeding chamber. The final segment indicates a scanning electron micrograph of the multi-branch stylet sheath formed from the pyriform scale of the video.
