The Wormy Wrigglers: Cross-Striped Cabbageworms, Beet Armyworms, and Cutworms
Thesewormsalso are the larva of various moth , but they opt not to be chunk together by their color or markings .
Cross-Striped Cabbageworms
Cross - striped cabbageworms assess about 3/4 inch long . They are blueish - grayish with shameful and yellow stripes along the distance of the side of their consistence and pitch-dark stripes across the width of their cover .
