Cecropia Cocoons. 



By William T. Davis. 



Cecropia cocoons of the " inflated" or " baggy" variety men-

 are to be found on numerous shrubs, but the most remarkable 

 specimens to be collected on Staten Lsland occur on the swamp 

 loosestrife or willow-herb {Decodon verticillatus) . This shrub 

 grows in the water and the cocoons have often been gathered 

 in winter by walking on the ice about the edges of the ponds 

 where the loosestrife grows. The cocoons, as a rule, are but 

 slightly above the level of the ice and, of course, run the risk 

 of inundation on occasions of very high water, and are also 

 liable to be eaten by mice and other enemies. Certainlj' the 

 greater number of these " inflated" cocoons are to be found at 

 the base of bu.shes, and ver)- often the caterpillars have in- 

 cluded several grass stems or other nearby growth as addi- 

 tional supports to the cocoons. This in it.self would account 

 for some of the largest cocoons — they are spun loosely between
