Oligia chlorostigma, commonly known as the Green-marked Brindled or Chlorostigma Brindled, is a species of moth belonging to the family Noctuidae (commonly known as owlet moths or cutworm moths). It is a member of the genus Oligia, which comprises various species of small to medium-sized moths often referred to as "brindled" due to their variegated patterns. The species was first described by Brandt in 1938.
Description
Oligia chlorostigma is characterized by its relatively small size, with a typical wingspan for moths of its genus. The most distinctive feature, and the origin of its scientific name, is a prominent
green mark or stigma on its forewings. The ground coloration of the forewings usually varies from dull brown to grayish-brown, often interspersed with subtle darker markings, streaks, or a brindled pattern. The hindwings are generally plainer and lighter in color, often a uniform grayish-brown. Like other noctuids, it possesses a robust, hairy body.
Distribution and Habitat
This species is primarily found in Western Asia, with its recorded distribution including countries such as Iran, Iraq, and parts of the Arabian Peninsula. Its preferred habitat often includes grasslands, steppes, open woodlands, and areas with herbaceous vegetation, which typically support its larval host plants.
Life Cycle
As with most moths,
Oligia chlorostigma undergoes a complete metamorphosis, progressing through egg, larval (caterpillar), pupal, and adult stages. Specific details regarding the larval host plants for
Oligia chlorostigma are not extensively documented, but generally, larvae of
Oligia species feed on grasses (
Poaceae) and various low-growing herbaceous plants. Adult moths are typically nocturnal, active during the night, and are often attracted to artificial light sources. The flight period usually occurs during the warmer months of the year, though precise timing can vary depending on geographical location and climatic conditions.
