Sycamore tussock moth

Halysidota harrisii

A species of Halysidota

The larvae have yellow-orange heads and bodies covered with hair, and they can grow to approximately 25–35 mm in length. They exhibit two pairs of long, orange hair-pencils and two pairs of white hair-pencils towards the front of their body. They also exhibit one pair of white hair-pencils near the back of their body. The adults are pale yellow with dark bands on the forewings. Each forewing is 24–26 mm in length, making the wingspan approximately 50 mm. As adults, they are almost indistinguishable from the closely related Halysidota tesselaris.

Life Cycle of Sycamore tussock moth
Egg The egg stage begins when a fertilized egg is laid. The egg of sycamore tussock moth is typically small, rounded, and may vary in color. Over time, an embryo develops inside, ready to hatch into a larva.
Larva After hatching, the larva (caterpillar) of sycamore tussock moth emerges, characterized by a segmented body with a voracious appetite for leaves. It grows rapidly, molting several times and changing size markedly with each molt.
Pupal The sycamore tussock moth enters a pupal stage inside a cocoon. This stage involves significant transformation, as the caterpillar's tissues reorganize into adult structures. The pupa is generally immobile and can vary in coloration.
Adult Emerging from the pupa, the adult sycamore tussock moth is recognized by wings and reproductive organs. The body is fully formed, exhibiting distinctive patterns and colors for recognition and mating. Adults focus on reproduction and dispersal.
