Lifehistory. Eggs are thrust into the tissue of the leaves of the 

 foodplant, being deposited singly during the day-time. The larva 

 hatches out after about a week and h-w\~, on the leaves, eating 

 holes from the edge and in the centre of the leaf. The young larva 

 is greenish grey but it becomes darker as it grows until it is 

 greenish-black when full-fed. It looks much like a Lepidopterous 

 larva, but is easily distinguished by having eight pairs of prolegs 

 besides the three pairs of thoracic (true) legs. When full-grown it 

 constructs a cocoon in the soil ; pupa] period from 10 days upwards. 

 In some districts (Coimbatore) this insect is only found during the 

 cold weather (November February) ; in others (Bellary) it has been 

 found during the South-West Monsoon (August). 



Foodplants- Mustard, cabbage, radish, cauliflower, turnips. 



Status.— A minor pest of cruciferous plants, sometimes doing 

 considerable damage to young seedlings. 



Control. (1) Handpicking of larvas. 



(2) Protection of plants by spraying Naphthaline Emulsion 

 or dusting with lime (20 pints) and kerosine (20 pints).
