Short trip to Wang Nam Khieo near Tap Lan National Park in Nakhon Ratchasima province, Thailand. There was a cultivated area with some secondary forest edges. Very interesting was a Arctiidae species from Venezuela (South Amerika), Pareuchaetes pseudoinsulata. These species was introduced to Sabah (Borneo) and Sri Lanka in 1973/74 for control of the Neotropical weed Chromolaena odorata (Compositae) and must be spreading to Malaysia and Thailand. About 3-4 years ago, I am know these species only from the southern part of Thailand and now I am discover these species also in the northeastern part of Thailand, about 1500 km from my last record in South Thailand.
