| Summary: | Morphology and biology of the fruit-piercing moth Ophiusa coronata (Fabricious) (Lepidoptera: Noctuidae) were studied in laboratory. Eggs were spherical and colored grayish green with an average diameter of 1.03±0.01 mm (mean±SEM). The larvae were looper caterpillars, possessing 2 white bands on the black head. The body was brown to blackish, marked with black spots and red longitudinal streaks. The pupa was black-brown. The adult moth had rufous and fuscous forewings tinged with a black spot in the middle. The hind wings were bright yellow in ground color with a dark band at the anterior and the posterior borders. Time required for egg to adult development averaged 40.35±0.59 days (mean±SEM). The average duration for egg, larval and pupal developments were 4.0±0.0, 23.20±0.49 and 13.15±0.22 days, respectively. Sexual maturity for female took 10.67±1.05 days. The average duration of egg laying, number of eggs and longevity of adult moths were 7.33±1.28 days, 333.0±171.82 egg/female and 22.83±2.45 days, respectively. Feeding preference and phototaxis of adult studies showed that adults likely preferred to feed ranking from slices of pineapple, banana, papaya and citrus, whereas sapodilla and rose apple were rarely fed on. Blue light and mercury vapor light were highly attractive, whereas violet light and fluorescent light were less attractive to this adult moth species.
