Geographical Distribution and Status of Actias Moths in Thailand



Geographical distribution and status of Actias moths was assessed at 46 forest stations throughout Thailand from January 2004 to December 2006. At each station, an eighteen watt black light was operated against a white sheet from 6:00 pm to 6:00 am daily. All Actias moths were observed and collected twice during the trapping period at 10:00 pm and 6:00 am. Distribution, abundance, seasonality and status were analyzed. Three out of the four Actias species previously encountered in Thailand were collected: A. maenas Doubleday, A. selene Hübner and A. rhodopneuma Röber. A. maenas was the most widespread species in the country with an average of 0.001037 individuals/spot sample and was found all year round. The highest abundance was in Narathiwat province, the northernmost border of the Sundaic region. A. selene was found at higher latitudes ranging from 20 °N at Doi Chiang Dao, Chiang Mai to 13 °N at Prachub Kirikhan province with an average of 0.003303 individuals/spot sample and were found all year round, with the highest abundance in July. By applying IUCN Categories & Criteria A. maenas and A. selene were designated as Vulnerable (VU) and Near Threatened (NT) species respectively. A. rhodopneuma moths were found only at Doi Phuka National Park, Nan province with 0.000263 individuals/spot sample from February to April and are therefore designated as a Critically Endangered (CR) species. A. sinensis was not found during this study and is therefore assigned the status of extinct (EX).
