Jersey, it can be found from May until November, sparingly before 

 midsummer and commonly until late September. The larva is bright 

 yellow or greenish yellow banded with shining black and furnished 

 with black, fleshy, thread-like appendages on the second thoracic 

 and eighth abdominal segments. It feeds on several species of 

 Asclepias and in New Jersey there are three broods. This butterfly 

 migrates in late fall. In May scattering females (and males accord- 

 ing to Mr. W. T. Davis) return and provide for the first brood 

 of larvae. The adults developing from these eggs give rise to a 

 second brood of larvae and the butterflies developing from the third 

 brood of larvae leave in swarms for the south during late September 

 and early October. 



Various references to publications on the life history and habits 

 of this species can be found in Edwards' Catalogue (Bull. 35, U. S. 

 Nat. Mus.) and numerous papers on this insect have appeared in 

 the entomological journals and popular magazines. An interesting ac- 

 count of the migration of this species and its routes to the south and 

 return can be found in a paper by Mr. Howard J. Shannon entitled 

 "Insect Migrations as Related to Those of Birds" (Scientific 

 Monthly, Sept. 1916). 



Anosia "berenice Cramer (Lep.). 



This and the variety strigosa Bates which are confined to the 

 southern portions of the United States and South America are also 

 Asclepias feeders. Edwards (Bull. 35, U. S. Nat. Alus., p. 18) lists 

 references to the literature on the larva of bcrcnicc. 



Mamestra legitima Grt. (Lep.). 



In Insect Life (Vol. II, p. 382, 1889-1890) this species is recorded 

 as having been reared during the spring of 1889 from a larva found 

 feeding within a seed pod of Asclepias incarnata near LaFayette, In- 

 diana, early in November, 1888. Howard (U. S. D. A. Yearbook, 

 1898, p. 142) figures the larva, pupa and adult of this species and 

 notes its occurrence and injury in tobacco fields of southern Vir- 

 ginia. Chittenden (Bui. 10, n. s., Div. Ent. U. S. D. A., p. 60, 1898) 

 states that larvae were found on asparagus plants at Marshall Hall, 

 Md., October 12, 1896. Smith (Ins. N. J., p. 457) records the food
