The Common Tit has been found in a
variety of localities in Singapore, from the mangrove-type environment
of Sg Buloh Nature Park, to the forested Central Catchment and even in
downtown Singapore along traffic congested Victoria Street ! At the
last location, the caterpillars of the species were found feeding on the
roadside ornamental plant Ixora javanica (Javanese Ixora) in the
heart of town. This is probably a new record of the host plant for
this species. The caterpillars collected were bred to adulthood.
The upperside of the male is deep
purple blue with a large circular brand on the forewing disc. The
female is dull grey-brown and black marginal spots on the greyish white
tornal area of the hindwing. The undersides of both sexes are a pale
greenish grey with a cell-end bar and a narrow reddish brown post discal
line on each wing. There is an orange-crowned black spot and a smaller
one on the hindwings.
There are two tails originating
from veins 1b and 2 from the hindwing. The species behaves in the
typical Lycaenid behaviour of sliding the hindwings in a fashion where
the tails appear to be alive. This acts as a decoy to fool predators
into thinking that the rear end of the butterfly is the head with the antennae
and "eyes". |
