REPORT OF THE STATE ENTOMOLOGIST I914 35 



abundant on restricted areas in both counties and estimated the loss 

 at less than $1000. 



Wyoming county. Mr H. M. Bowen, manager of the county farm 

 bureau, reported that the army worm was not prevalent throughout 

 the county and records injury to only one or two fields. 



In addition to these, negative reports were received from Clinton, 

 Delaware, Oneida, Onondaga, Otsego, St Lawrence and Ulster 

 counties. The Entomologist, from personal knowledge, could add 

 several others to the list of counties where there was very little or no 

 injury by the army worm. 



Description. The eggs are rarely seen; they are smooth, white 

 when first laid, turning gradually to a pale straw color before hatch- 

 ing, and are usually deposited in masses glued together by an adhesive 

 substance. The practical point in this connection is that the moths 

 generally select the toughest stalks of the thickest clumps of vegeta- 

 tion when about to deposit eggs. 



Young caterpillars. The young caterpillars, likewise rarely 

 noticed, have a brownish black or yellowish head with dark eyes, 

 the body being dull transluscent white with minute scattering hairs. 

 These young caterpillars are only about .07 of an inch long and walk 

 in a looping manner. 



Full-grown caterpillars. The full-grown or nearly full-grown 

 caterpillars, the stage usually attracting attention, present quite a 

 range of color though the general appearance is fairly characteristic. 

 The larger caterpillars are about one and one-half inches long. 

 They may be recognized by the median white line beginning at the 

 head and extending a variable distance along the back; in some of 

 the lighter and younger ones it may be traced the length of the body. 

 Either side of the median white line there is a brown, broad stripe 

 more or less distinct, which may be mottled with white in the lighter 

 individuals; this stripe is bordered laterally by a narrower one of 

 dark brown. Next there is a white line similar to the median one 

 but more constant, and between it and the next white line there is a 

 stripe of variable brown sometimes mottled with white; this is 

 usually lighter than the stripe on either side of the median white line ; 

 the stigmatal stripe comes next and this, in well-marked individuals, 

 is the most striking, it being as dark as any, and below it there is the 

 white substigmatal stripe; these last two are somewhat variable. 

 The ventral surface is a variable yellowish green. The prolegs or 

 abdominal legs are brown at the base. 



Pupa. The mahogany brown pupa is about three-fourths of an 

 inch long, rather stout, and at the posterior extremity there is a pair
