Ostrinia nubilalis, commonly known as the European corn borer, is a moth species native to Europe and invasive in North America. It has a wingspan of 2.5-3.5 cm and is known for its distinctive pale yellow or tan wings with wavy brown lines. This species is a significant agricultural pest, primarily of corn, but also affects other crops such as sorghum and peppers. The larvae bore into plant stalks, causing structural damage and decreased yield.

Ostrinia nubilalis, commonly known as the European corn borer, is native to Europe. Its geographical distribution has expanded, and it is now found in North America as well, primarily in the United States and Canada.

The European corn borer typically inhabits temperate regions where its host plants, primarily corn, are cultivated. It thrives in areas with warm summers, as the larvae require sufficient warmth to develop. The regions it inhabits are generally characterized by agricultural landscapes with sufficient moisture for crop growth.

Ostrinia nubilalis occupies an ecological niche as an agricultural pest, particularly in corn fields. It feeds on the leaves, stalks, and reproductive parts of corn plants, which can cause significant yield losses. The species has also adapted to feed on a variety of other crops and wild plants, demonstrating its ability to exploit various ecological niches within agricultural and semi-natural environments.
