Larvae: The larvae of the leaf minor makes a tunnel inside the leaf tissues and feeds on chlorophyll. It makes zigzag tunnels on the leaves.
Pupa: The larvae of the leaf minor converts into pupa within 2 to 20 days.
Adult: The leaf miner comes out after 6 to 22 days. It completes many generations throughout its life cycle. Adult appears in yellow color with black stripes on the abdomen.
