Agricultural Pests

Infestations of red slug caterpillar can range from mild to severe, depending on the population size. Larvae feed on leaves, leading to defoliation that impedes plant growth and reduces yields. In large numbers, they can devastate crops, which may result in economic losses. Moreover, this extensive plant damage may lead to secondary infections, potentially affecting food supply and prices.
