196 CATERPILLARS AND THEIR MOTHS 



two or three years we had the same experience, but 

 the next year gave us a moth or two, and w^e found 

 out that it was astylus. 



Later we found a moth which laid many eggs — for- 

 tunately, for astylus is a very delicate caterpillar, in 

 our experience, and needs the most favorable condi- 

 tions in order to thrive. 



The eggs were almost globose, apple-green, and 

 shining. They grew j^ellower, and before hatching 

 the red Caudal horns could be seen very plainly. The 

 egg-period was eleven days with the first brood, ten 

 with the second two years later. The eggs hatched in 

 the evening, but fortunately we had provided blue- 

 berry-twigs, and could supply food at once. 



The caterpillars were pale green, granulated, and 

 had stout caudal horns, bifurcated at the tip, which 

 was dark red, the horn growing lighter red to the 

 base, and having a yellow band in the middle. 



The first brood molted on the ninth, the second on 

 the eighth day. The first brood was as before, except 

 that the head was more pointed, yellow horizontal 

 lateral lines appeared on the thoracic segments, and 

 the legs were red. The second brood gained these 

 marks and yellow obliques, a red dot at the apex of 

 the now pointed head, and red patches on the subdor- 

 sal and stigmatal regions of some larvae. Other larvae 

 lacked these patches. The red was bright carmine, 

 and the patches were larger and more irregular in 

 shape than those of myops. 



The second molt followed in six days for both broods 

 and brought no changes, except that the horns were 

 less bifid, or had the two points shorter.
