There are 5 Zizina species. All were
formerly regarded as subspecies of otis
but are now recognised as distinct species. They are
antanossa which occurs throughout
Africa, labradus which is found in
Australia, oxleyi which is endemic to
New Zealand and emelina which is
confined to Tibet and western China.
There is still a great deal of
confusion regarding the distribution of the 'true'
otis, but current opinion is that it
occurs in India, Sri Lanka, Myanmar, Thailand, Cambodia, Laos,
China, the Philippines, Malaysia, Sumatra, Borneo, Sulawesi, Java,
Bali and New Guinea.
This species can be found in almost any open grassy habitat
including forest clearings, riverbanks, roadsides, parkland and
gardens, at elevations between sea level and about 1500m.
foodplants are Mimosa,
Lotus and Indigofera ( Fabaceae
Both sexes flutter constantly just above ground level, pausing
occasionally to nectar at daises and other low growing flowers. In
hazy sunlight they will bask on the ground, with their wings half
open. They roost overnight on low vegetation or on bushes.
