moths come from the South each year. The only remedy 

 is hand picking. It is doubtful if they will ever become 

 very injurious in the Northern states, since they do not 

 begin their work there until late in the season. 



Parsley Worm or Celery Caterpillar (Papilio asterias). 

 This worm eats the foliage of celery, carrot, parsley, and 

 allied plants, but is not very of ten injurious. The mature

 The female deposits her eggs near the ground on the stems 

 or roots of wheat, oats, grasses, etc. 



Remedies. The burning of rubbish accumulations along 

 headlands, fences, etc., in the winter or early spring in 

 infested localities will destroy many. They always infest 

 the small grains before they do corn. 



While these insects have wings they use them but little 

 in their migration in summer, but they travel on foot and
