The moths fly mostly during July and the first half of August. 

 This insect is one of the larger Crambids and is easily recognized 

 by the broad white stripe near the edge of the wing. This stripe 

 is broken by an oblique rufous line near the outer third of the 

 wing ; and the basal half of the stripe is divided longitudinally by 

 a faint yellowish line. This species is quite prolific ; one female 

 has been known to lay five hundred and twenty-five eggs. The 

 eggs hatch in about ten days. 



The young larvae are strong and begin to feed at once. They 

 soon construct nests of the t5^pical form. (Fig. 7.) As the larvae 

 grow older their straw colored bodies become darker till in Septem- 

 ber they are a mottled dark brown. Early in November the larvae 

 close their nests and retire for the winter. In the spring the 

 larvae complete their growth, pupate, and emerge as adults in 

 July. 



Egg. — Creamy white when first laid, gradually turning to an orange buflf 

 color before hatching. Form elliptical oval ; size .42 mm. by .33 mm. 

 There are about sixteen longitudinal ridges and numerous smaller transverse 

 ridges. 



Larva, first stage. — Head diameter .225 mm.; body diameter .14 mm.; 

 length .625 mm. Head a deep brown, thoracic shield a lighter brown ; body 

 a straw color with a reddish mark along the middle of the back from the 

 fourth to the ninth segments inclusive. Scattered light colored hairs occur 

 on the head and body.

This species resembles in a general way the White Striped 

 Crambus, yet it is quite different in some respects. It may be 

 recognized by the narrower white stripe along the costal edge of 

 the narrower fore wing ; the stripe is not broken near the tip nor 

 is it divided longitudinally. The tip of the fore wing is also 

 more pointed and the outer margin more strongly curved than in 

 the White Striped Crambus. The moths fly the latter part of the 

 afternoon and during the earlj^ evening.
