Larval body segments were annulate, with four to six annulets 
each, and covered with numerous short secondary setae that gave a 
velvety appearance. On each of the nine spiracular segments, the 
spiracles were situated between annulets 2 and 3. 
First instars had long black setae on the head (5 pairs) and 
prothorax (2 pairs), and on abdominal segments 9(1 pair) and 10 (2 
pairs.). On the prothorax, a third (lowermost) pair of long setae was 
pale. Later instars lacked either long or black setae. Second through 
fourth instar heads (Figure 5) had many more setae, and these were 
raised upon chalazae. While a few were simple slender setae, most 
were thick, with expanded truncate tips. Final instars had short thick, 
but pointed setae, also raised upon chalazae. The labrum was 
emarginate in all instars. 
Durations of the immature stages are shown in Table 2. 
During the late afternoon and early evening preceding pupation, 
the fifth instar larva prepared a silk girdle; ecdysis to the pupal took 
place later the same night.

Pupae 
The waxy green pupa (Figure 4) was spindle-shaped due to its 
tapered ends and the curved expansion of the ventral line of its body. 
The following measurements were made: total length of pupa (29 
mm); dorso-ventral thickness of pupa at point where girdle crosses 
dorsum (6 mm); lengths of prothorax (2.5 mm), mesothorax (3.5 
mm), metathorax (1.5 mm), median cephalic projection (5 mm), 
maxillae (16 mm), prothoracic tibia plus tarsus (8 mm), mesothoracic 
tibia plus tarsus (10 mm), antennae (15 mm), and mesothoracic wings 
(12 mm). 
The maxillae terminated at a point 1.5 mm before the wing apices. 
The metathoracic legs were covered except for their extreme tips. The
