Excerpt from Cassell's Natural History, Vol. 6: Illustrated The development of the ovipositor is very different in the females of different genera and species of Ichneumons, and this stands in direct connection with their habits. In the females of some forms the ovipositor scarcely projects from the extremity of the abdomen, whilst others have a long, bristle-like organ two or three times the length of the body, and between these two extremes every gradation occurs. The short ovipositors are possessed by species which deposit their eggs in or upon easily accessible larvae the long ones characterise those which seek concealed larvae, such as the grubs of wood-eating Beetles.
