Asota plana Walker, 1854. A moth in the family Erebidae in the superfamily Noctuoidea which is found between 1,000 to 1,900m. I took this photograph at Doi Ang Khang, in northern Thailand, well below the peak at 1,928 metres. The subspecies Asota plana plana is found in China, India, Indonesia, Japan, Laos, Malaysia, Myanmar, Nepal, Sri Lanka, Thailand and Vietnam. The larvae are very striking, coloured black with yellow rings around each segment and festooned with long white hairs; definitely aposematic! (1). The host plant is said to be Ficus (Moraceae).
The moth flew onto a pane of glass, which resulted in an attractive photograph (below) even though it was taken with a small compact camera. I have rotated the image from the vertical to the horizontal plane for added impact! It is one of my favourite images and shows that you do not need to spend a lot of money on equipment to get interesting images. But you do need to get lucky now and then!
The large, and very attractive moth, Asota (=Anagnia) subfascia, shown below, is another member of this genus. This specimen appeared on the balcony outside my hotel room one night in Pattaya. Another species with a wide distribution, including India, Thailand, Peninsular Malaysia, Indonesia, the Philippines and Taiwan. It seems to have gone through a number of name changes as it was also previously named, Peridrome subfascia Walker, 1854.
I am a retired entomologist with a background in quarantine pests and invasive invertebrates. I studied zoology at Imperial College (University of London) and did a PhD on the population dynamics of a cereal aphid (Metopolophium dirhodum) in the UK. I spent 5 years with the British Antarctic Survey studing cold hardiness of Antarctic invertebates and 17 years with the Food and Environment Research Agency. My main interests now are natural history, photography, painting and bird watching.
