. The Biological bulletin. Biology; Zoology; Marine biology. BLACK EYE I HEAD BLACK •EPIDERMIS RETRACTS FROM PUPAL CUTICLE. 2-3 5-6 6-7 9 DAYS 14 21-30 Figure 1. Time-table for the development of Mormoniella. The approximate times at which the cuticle detaches from the epidermis (signaling the end of an instar) are indicated by stippling. revealed until the cuticle of the last larval instar is shed, an event occurring 24 to 48 hours later. The so-called prepupa is simply the pupa enclosed within the last larval cuticle. Likewise, the pupal stage ends with the detachment and retraction of the pupal cuticle, although the adult does not emerge for 4 or 5 days. During this period the wasp, which is properly called a developing adult, is enclosed in two cuticles—an inner adult cuticle and an outer detached pupal cuticle, which is shed at eclosion. The exact time at which epidermis retracts from the pupal cuticle, marking the end of the pupal period, has not been definitely determined for Mormoniella. Our observations agree with those of Tiegs in suggesting that this occurs within 24 hours after shedding the final larval cuticle. Under certain conditions, just prior to entering the resting stage the larva ceases development and enters diapause (Schneiderman, 1957; Schneiderman and Horwitz, 1958). At room temperature diapause persists for a year or more.
