Oleander Caterpillar

Description

The Life Cycle of the Oleander Caterpillars

The oleander caterpillar, scientifically known as Syntomeida epilais, undergoes a fascinating life cycle comprising four primary stages: egg, larva (caterpillar), pupa, and adult moth. Understanding these stages is essential for effective management and control.

The life cycle begins when the adult female moth lays clusters of bright orange eggs on the undersides of oleander leaves. These eggs typically hatch within 3 to 5 days, giving rise to the larval stage. The larvae, or caterpillars, are initially orange with black hairs but eventually develop a striking black body with white spots and long, tufty black hairs. This larval stage is the most destructive as the caterpillars feed voraciously on oleander leaves, causing significant defoliation. The caterpillar stage lasts approximately 2 to 3 weeks.

After reaching full size, the caterpillars transition to the pupal stage. They form cocoons, usually attached to the host plant or nearby structures. This stage lasts around 10 to 14 days, during which the caterpillar undergoes metamorphosis into an adult moth. The adult oleander moth, also known as the polka-dot wasp moth, is predominantly metallic blue with white spots and bright red abdomen, a striking appearance that belies its harmless nature. Adult moths primarily emerge in the warmer months and live for about a week, focusing on reproduction.
