100 CATERPILLARS AND THEIR MOTHS 



After once knowing I'meata in all its stages we have 

 often found nearly full-grown larvte on the unshaded 

 ground in the garden, feeding on purslane, with the 

 midday sun beating down on them. This is unusual, 

 for most moth-larvcie, even if feeding at noon, would be 

 under the shelter of leaves or behind a tree-trunk 

 out of the direct rays of the sun. We have never 

 found lineata on woodbine, but other entomologists 

 have. 



On the thirtieth day from the egg they began to 

 crawl restlessly about, stopped eating, chewed holes in 

 the scrim over the box, and then spun loose webs like 

 a fish-net between leaves and the tin, crawling about 

 for nearly two days before spinning. In three days 

 the pupffi were free from the caterpillar-skin. Ima- 

 gine our surprise a few years later to have a brood curl 

 up quietly without spinning a thread, and part of an- 

 other brood go into earth only deep enough to cover 

 them, and there pupate without spinning. This shows 

 that one brood does not teach everything about the 

 habits of the crawlers. 



The pup^e were nearly two inches long, slender, 

 slightly pitted on the abdomen and of a pale tan-color 

 — the lightest-colored sphingid pupa we know, except 

 Ampelophaga myron. The head was much prolonged, 

 the tongue-case not raised above the wing-covers. The 

 eyes were well defined. The anal hook, or cremaster, 

 ended in two short points. 



• rpjjg eggs of the brood so fully described were laid on 

 June 10, and on August 11 the first moth emerged be- 

 tween 12 : 45 and 2 p.m., while we were at luncheon. 



The moths are very beautiful. The head, thorax, and
