Content
Wingspan 13-18 mm. Adult fireworks are golden brown [5] . Adult caterpillars are up to 25 mm long, yellowish-green [5] .
Caterpillars feed on the leaves of plants - sowing oat , coconut palm , peasant blackberry , dagussa , barley ordinary , banana palm , ordinary tobacco , sowing rice , millet ordinary , Pennisetum glaucum , sugarcane , Saccharum spontaneum , moghar , sweet corn and sorghum . Before they begin to feed, the caterpillars longitudinally fasten the edges of the sheet together, thereby forming a sheet tube or sheet envelope [2] [4] . Caterpillars remain inside the folded "house" and feed on green tissues (mesophilic layer) of the leaf there, leaving white spots abnormal for the leaves [2] [4] .
Females are able to lay up to 300 disc-shaped eggs on the tip of the leaf at a time. The incubation period of eggs lasts 4-6 days [5] . Usually caterpillars go through 5 stages of development, but on older plants they can go through one or two stages. The caterpillar stage lasts 3-4 weeks. Pupa stage 6–10 days [5] .
Caterpillars are pests of some cultivated plants, including oats, coconut palm, barley, tobacco, rice, sugar corn [4] . Caterpillars infect plantations a month after sowing seedlings , and this process can continue until the crop ripens. The action of caterpillars greatly affects the development of shoots , which is why caterpillars cause a loss of 5-60% of the crop [2] . In rice fields in the state of Madhya Pradesh (India), Cnaphalocrocis medinalis in combination with another pest, Parapoynx stagnalis , caused the loss of 80% of the rice crop [4] .
