The larvae feed on the leaves of oak trees in the eastern United States and southeastern Canada and are a major defoliator of oak trees, which can lead to ...
Fully grown caterpillars are green and measure around 16.5 millimeters in length. The entire life cycle of this moth spans about 5 weeks. Throughout its life stages, the rice leafroller can cause significant damage to crops. Newly hatched caterpillars initiate damage by cutting leaf edges and folding them.
The species is primarily known as a pest of kiwifruit (Actinidia deliciosa), but the caterpillars feed on various other trees with fleshy fruit, such as Citrus, hawthorns (Crataegus), persimmons and ebonies (Diospyros), gum trees , fuchsias (Fuchsia) and grapevines (Vitis). They primarily feed on the leaves, but can also damage the husk and ...

As the larvae grow bigger they eat larger leaves, and then roll themselves up in a full-sized leaf to pupate. Larvae occur from April to June; adults are on wing in June and July. [1]

[2] It communicates with other cherry leaf rollers by scraping, plucking and vibrating. [3]
