Larva: Flattened, squarish, head retracted, feet short, on joints 7 to 

 10 and 13. Three rows of low, flattened warts with short, stiff hairs, those 

 from the third row (tubercles iv -\- v) longer. Pale olivaceous or pinkish ; 

 a broken black dorsal line with adjacent dots on joints 5 and n before the 

 upper wart; a line above and below the second wart (tubercle iii), broken 

 in the incisures, a little curved on each segment, the upper one bordered 

 above faintly by white. Upper two warts blackish, the third pale except on 

 joint 6. Spiracle on joint 5 moved up. An eversible area around the 

 spiracle on joints 6 and n. Hairs finely segmented with a clear bulb at 

 the extreme base, dusky* on upper warts, pale on third. Another row of 

 warts present on the thorax. In a green specimen the dorsal markings on 

 joints 5 and 10-11 are larger. It has the appearance of a narrow dorsal 

 and broad lateral gray bands. The larvae are small ; length, 8 to 9 mm. 

 They very much resemble the holes which they eat in the leaves. Winter 

 passed as chrysalis in cocoon.
