Large, dark-coloured moths some nearly the size of a human hand have been spotted all over Singapore in recent weeks, drawing curious onlookers from Raffles Place to Woodlands.

Since the middle of last month, nearly 800 sightings of the Lyssa zampa, or tropical swallowtail moth, have been reported online, said National University of Singapore ecologist N. Sivasothi, who is recording sightings on the NUS Habitat News website.

They have been seen at many places, including office buildings, HDB corridors, schools and parks.

The moth is present here year-round, but is more commonly seen between May and August. Ecologists say the last major flurry of sightings was in 2005, with minor spikes every year or so since.
