American Serpentine Leafmine: Liriomyza trifolii

These native Liriomyza leafminer species are closely related, have a similar biology and because they have a similar appearance, are often misidentified. L. sativa is the more commonly found on vegetables and melons during the summer and fall, whereas L. trifolii is more abundant during the spring and early summer. These two species attack a wide range of plants and have been reported on over 50 host crops including carrot, celery, cucumber, broccoli, cabbage, lettuce, melon, onion, pepper, potato, squash, and tomatoes. They can also be found in varying intensity during the summer on cotton, alfalfa, and safflower. Ornamental flower crops such as chrysanthemum, gerbera, gypsophila, and marigold are readily attacked as well as a number of broad-leaved weed species such as nightshade, sunflowers and groundcherry.
