The eggs are white first, but they turn darker when they get older. They are globular and about 1 mm in diameter.


Eggs are laid in a long column stretching up the stem, under a leaf sheath. They hatch after about 10 days.

Emergence hole in the stem, made by caterpillar of stalk borer. The young larvae are deep purple or black in colour.

They crawl up the plant into the funnel. The early stages of the caterpillars feed on the leaves in the funnel of the plant.

When the attack is severe, the shoot may turn yellow and die. If the plant dies, the caterpillars will move to another plant.

If the plant survives, the later stages of the caterpillar will bore into the stem and feed there on the central tissue of the stem. The larval period takes 35 days or more.

When fully grown the caterpillars are up to 40 mm long. They have a pinkish white colour and small black spots along the sides of the body. The mature caterpillar cuts a hole in bussoela stem before pupating within the tunnel.
