PAONIAS ASTYLUS 199 



The eggs were all laid in July, the first lot on the 

 9th, the second on the 29th and 30th, and pu- 

 pation took place from September 12 to October 22, 

 the last brood being the slower in growth. No moths 

 emerged before the following June, about the 20th. 



We think astylus single-brooded in our part of New 

 England, but it may be douljle-brooded farther south, 

 where the warm weather comes earlier. 



The ideal place for astylus larvae is an old pasture 

 or roadside where clethra, blueberry, dangleberry, 

 inkberry, holly, " swamp-alder," and Viburnum lanta- 

 nokles are crowded in a tangle with bayberry, 

 beach-plum, andromeda, laurel, and azalea, with an 

 occasional pitch-pine and soft maple rising clear of 

 the crowd. It is an ideal place for other crawlers too 

 — thyshe on viburnum, Dolba hylcBus on inkberry, 

 choerilus on azalea, scapha on bayberry, Lagoa crispata 

 and SpJihir, kahnue on beach-plum (which is also food 

 for cecrojjta), JEacles impeyialis on pine and maple, and 

 jwlyphenius on maple ; while in the more open parts 

 the sweet-fern creeps in, offering very good chance of 

 Sphinx gordlus. Such treasure-places we know well, 

 and pass through them to the marsh for mignonette- 

 scented pogonias in June, and for cranberry-vines, 

 with berries of every color from apple-green through 

 yellow to deep crimson, in September. From one 

 clump of willows excoecatus leans toward us, while gem- 

 inatus and luna may be feeding on every poplar and 

 white birch in sight, and the folded leaves of the sassa- 

 fras tell where the butterfly caterpillars, troilus, have 

 been or are — " puppy-dogs " the children always call 

 them, though to us they were more like tadpoles in shape.
