Pest identification
and confirmation—Leafminers
On vegetables, the most common leafminers are the larvae of small flies belonging to the genus
Liriomyza, including the vegetable leafminer, serpentine leafminer, and pea leafminer.
Vegetable leafminers may be black except for a prominent yellow triangle between the bases of
the wings. The head behind the eyes may be mostly black. Other species may have the thorax covered
with overlapping bristles that give fresh specimens a silvery gray color. The area behind the
eyes may be yellow. The yellowish maggots and brown, seedlike pupae of the two species are too
similar to distinguish.
