Lifestages Of The Butterfly-Common Emigrant

Here are some pictures representing four stages of the life cycle of common emigrant butterfly.

1st Stage-Eggs

The female common emigrant butterfly lays its spindle shaped yellowish eggs individually on the back side of the host plants (Cassias). The main host plant in our area is sickle senna (Senna obtusifolia).

The caterpillar of common emigrant has agreen rough body with tiny black spots and a white lateral line sandwiched between an upper black spotted-line and a lower olive green stripe. The caterpillar reach a maximum length of about 35mm. The mature caterpillar generally stuck itself head-up under the leaf of the hostplant. A silken girdle helps it to stay in an upward position. The larval stage is completed in about two weeks.

4th Stage-Adult Butterfly

The Common Emigrant (Catopsilia pomona), also called the Lemon Emigrant or Lemon Migrant, is a medium-sized (wingspan: 45mm-60mm) pierid butterfly found in Asia and Austrealia. This butterfly gets its name from the migration habit.
They have a great variability in colors and marks. Both the male and female have pale white upper side with a black spot at the distal end of the forewing cell though this spot is sometimes absent in the male. In the male, the upper side of the apex of the forewing is narrowly black and continues partway along the termen and costa. In the female, the black bands are wider and are continued along the entire length of the costa and termen.
The male has a sulpher or pale green underside with or without a radish-brown spot on both the forewing and hindwing. The female has pale yellow underside with radish-brown spots including three or two white centered spots. In both sexes, except for a small area on the lower half of the forewing, which is unmarked, the remaining areas are marked with very fine brown lines.
