Definition
Eudocima anguina is a species of moth belonging to the family Erebidae, subfamily Erebinae. It is one of several fruit‑piercing moths within the genus Eudocima.
Overview
The species has been recorded in parts of South and Southeast Asia, including India, Sri Lanka, Thailand, and Indonesia. Adults are nocturnal and are attracted to fermenting fruits, where they use their robust proboscis to pierce the skin and feed on the juice. This behavior occasionally brings them into conflict with agricultural interests, particularly in citrus and tropical fruit production. The larvae are foliage feeders and have been observed on plant families such as Rubiaceae and Moraceae, though detailed host‑plant records for E. anguina are limited.
Etymology / Origin
The generic name Eudocima derives from the Greek elements eu (“good” or “well”) and dokimos (“approved” or “tested”), a term historically applied to a group of moths noted for their strong proboscises. The specific epithet anguina is Latin for “snake‑like” or “serpentine,” possibly referring to the wavy, banded pattern on the moth’s forewings that resembles the markings of a snake.
Characteristics
- Morphology: Adults display a wingspan ranging approximately from 70 to 85 mm, though precise measurements vary among regional populations. The forewings are typically brownish‑gray with intricate, wavy transverse lines and a series of pale spots; the hindwings are orange to reddish‑brown with a conspicuous dark border.
- Proboscis: Like other members of Eudocima, E. anguina possesses a heavily sclerotised, elongated proboscis capable of penetrating fruit skins.
- Life cycle: The species undergoes complete metamorphosis (egg → larva → pupa → adult). Eggs are laid singly on host plant leaves. Larvae are cylindrical, bearing setae and lacking conspicuous coloration; they pupate in loosely spun cocoons within leaf litter or shallow soil.
- Behavior: Adults are active at night and are attracted to light sources. Their fruit‑piercing activity can cause significant damage to commercial fruit crops, prompting the use of baited traps in some regions.
Note: Certain details, such as exact host‑plant species and precise distribution limits, are derived from limited regional surveys; comprehensive data are not yet available.
