very common one at Ithaca and is undoubtedly an important grass 

 pest. It is one of several found by Professor Webster causing 

 serious injuries to the grass and grain lands of Ohio in 1896. 



Description of early stages. The eggs are creamy white when 

 first laid, gradually turning to an orange-red color before hatching. 

 The young larva has a pale yellowish head flecked with sooty 

 specks and the body is dark, semitransparent, white with irregular 

 reddish blotches along the dorsum. Scattered dark colored hairs 

 occur on the head and body. 



Life history. This species appears to have an exceptionally 

 long breeding season, as adults may be observed from June to 

 September and possibly there are two generations annually. The 

 period of oviposition lasts a week or more. One female deposited 

 200 eggs the day after being captured, 200 the next day and 100 

 the third, and at the end of the week had produced 727 eggs. 



Yellow Crambus 



Crambus latcolelhis Clem. 

 This rather uniform, yellow Crambid with a wing spread of 24 

 to 1 inch, appears to be confined to low, wet lands, the moths being 

 abroad at dusk during the latter part of June and July. It was a 

 rare species at Ithaca, though Professor Webster lists it as one of 

 the five species responsible for extensive injuries to the grass and 

 grain lands of Ohio in 1806. Practically nothing is known of its 

 early stages except that the eggs are a light reddish color when 

 first laid and ornamented with 14 prominent longitudinal ribs. 

 It is closely related to the following species. 



Sooty Crambus 



Crambus caliginoscllus Clem. 



This small, dark colored moth with obscure markings has a wing 

 spread of from ^ to 1 inch. The adults are abroad In early even- 

 ing during the latter part of July and the first week of August, 

 very few being attracted to lights. 



This insect is best known because of its injuries in the corn and 

 tobacco fields of Maryland. It does not appear to be an abundant 

 or destructive form in New York State. 



Description of early stages. The eggs arc creamy white when 

 first laid, gradually turning to an mange red color. The young 

 larva has a pale amber head and is a dirty, translucent white with 

 irregular, reddish spots on the middle line of the back. Scattered 

 light colored hairs occur on both the head and body.
