| The pupa is fastened to this pad by a spiny hook or process, the cremaster, on the last abdominal segment. |
| A typical noctuid pupa, shiny reddish-brown in colour, about 16 mm long, and with two distinct terminal cremaster spines, and normally not identifiable to species. |
| Warm water relaxes the cremaster muscle and allows scrotal lengthening. |
| This hook-like projection is called the cremaster, and it serves a very important purpose in holding the chrysalis in position. |
| The cremaster, which is short, is bent upward at an oblique angle with the line of the ventral surface. |
