Detail of cremaster (posterior end of pupa).  Dorsal side on left, ventral side on right.
The cremaster is strengthened by the two longitudinal dorso-lateral ridges

Closeup of bristles on the cremaster, which are flattened for strength and hooked at the ends
so that the pupa can anchor itself to the silk lined shelter (in the same manner as velcro)

Posteriorly directed bristles on the posterior parts of the pupa abdomen that help position
the pupa and prevent it from sliding down inside the shelter.
The hairs are strengthened by the half-conical bases which stop the bristles from bending over.
(The anterior side of the bases is to the left)
