Common in southern Indiana, March 11 — Dec. 1; not taken 

 north of Marion County though probably occurs sparingly 

 throughout the State. Hibernates as imago beneath cover on 

 the ground and beneath loose bark of logs and snags. In late 

 autumn and early spring taken by sifting dead leaves and other 

 surface debris. In May and June taken on foliage of various 

 kinds, especially that of red-bud, Cercis canadensis L., along the 

 borders of thickets and in open woodland. In late summer and 

 early autumn found on weeds and grasses in timothy meadows 

 and waste places. 



Dunedin, Fla., scarce, March 14 — 28, swept from herbage in 

 low moist grounds (W. S.B.). Recorded only from Sanford 

 and Tampa, that State. Lakehurst, N. J., July 12 {Davis). 

 Agricultural College, Miss. {Weed). Its known range extends 

 from New England west to Colorado and south and southwest 

 to Florida, Texas, Arizona and Mexico. Uhler (1876, 301) 

 says that: "In Maryland it may be found by beating rank 

 growths on the borders of woods ; the first brood late in May 

 to early in July, the second August — October. It hibernates as 

 adult." Hambleton in an excellent account of its life history 

 (1909, 272) states that the native food plant is a smart-weed, 

 Polygonum pennsylvanicum L., which is common throughout the
