Large Rose Sawfly Laying Eggs

By Dr Anthony Cooper (Leicestershire, United Kingdom)

This large rose sawfly, Arge pagana, was laying eggs on a rose bush by the photographer’s front door. Anthony Cooper observed it as it gradually worked its way down the stem, moving slightly between each insertion of its ovipositor to lay the next egg.
