​cabbage  loopers / worms

Greenish- gray worms The looper has legs in the front and back and none in the middle, causing the body to arch in a looping motion as it moves. They bore into vegetables and can be seen as holes. Their droppings look like small, dark crumbs. Commonly found in cabbage, cauliflower, and peppers. In root vegetables such as beets and radishes, they are off-white. In carrots they can be orange. (It is not common to find worms in root vegetables in the United States.)

spider mites

Although related to insects, mites aren’t insects but members of the arachnid class along with spiders and ticks. Spider mites are the most common mite pests and among the most ubiquitous of all pests in the garden and on the farm. Spider mites' puncture-and-suck mode of feeding produces yellow or white stippling and leads to reddish or pale discoloration of leaves. Plants lose vigor and become unthrifty. ​
