Light Brown Apple Moth
Scientific Name: Epiphyas postvittana
Order & Family: Lepidoptera (Order), Tortricidae (Family)
Size: Typically about 8-10 mm in length (approx. 0.4 inches) with a wingspan of 15-25 mm.
Natural Habitat
Originally from Australia, but now found in New Zealand, the United Kingdom, Hawaii, and parts of the US (California). They thrive in orchards, vineyards, nurseries, and gardens with specific host plants.
Diet & Feeding
The larvae (caterpillars) are highly polyphagous, feeding on a vast range of over 2,000 plant species including apples, grapes, pears, citrus, stone fruit, and berries.
Behavior Patterns
Adults are nocturnal and attracted to light. The moth rests with its wings folded in a bell shape. Larvae are 'leaf rollers' that use silk to tie leaves together to create a sheltered feeding site.
Risks & Benefits
Risks: Considered a significant agricultural pest, especially for fruit crops. The larvae damage fruit and leaves, causing economic loss. Benefits: No significant benefits to humans; they serve as a food source for some predators like birds and wasps.
