beetles included under the heading of turnip flea beetles 
but they are similar in their mode of attack. They

each of its outer wings. Its antennae are one-half the

down to form a kind of foot. 
In addition to turnips, other cruciferous crops, such 
as swedes, cabbages, and rape, also suffer. Recently the 
turnip flea beetle was found attacking young barley 
plants. This was no doubt due to the absence of 
cruciferous plants.
