While this moth species can be seasonally abundant, photographs of mating pairs appear to be rare in publications. While the wings may be folded up like a butterfly while mating, it rests in typical moth fashion with its wings spread wide open. This attitude of rest has been described as ‘very much like that of a specimen set and pinned in a collection’ (Tweedie & Harrison, 1977: 137, as Nyctalemon patroclus). Lyssa zampa resembles a butterfly as it has relatively smooth antenna. This species is widespread throughout the Indo-Australian region (Fox, 1986: 80).

Although Lyssa zampa is seasonally common in the urban areas of Singapore, aspects of its ecology and behaviour are apparently not well known. This moth is known to puddle beside forest streams to obtain salts and minerals (Leong, 2014). Records of Lyssa zampa visiting flowers appear to be rare. As the adults of this species have a functional proboscis, it is likely they may derive nutrition from the nectar, and perhaps even serve as a pollinator.

Moths and butterflies may occasionally be witnessed drinking from the edges of pools, puddles and streams in their quest for salts and minerals (Smedley & Eisner, 1996). This activity is known as puddling (see Khew, 2010: xiii). Moths puddle mostly at night, which would be the reverse of butterflies which puddle during the day. A puddling Lyssa zampa keeps its wings folded upwards, most likely to prevent them from getting wet. Lyssa zampa is seen in large numbers outside the forest at certain times of the year, but it has only been observed to puddle along the banks of forest streams (personal observations). The continued protection and preservation of forests and the streams therein will thus help to sustain the lives of these moths and other native Lepidoptera in Singapore.
