Common Bluebottle or Blue Triangle

Graphium sarpedon luctatius


The larva, pupa and imago of the Common Bluebottle or Blue Triangle butterfly. The larva begins as blackish or dark green with numerous spines then turns into green with a bright green or yellow band on the fourth segment and has short spines on the 2nd, 3rd and 4th segments. The girdled chrysalis often hangs from leaves or twigs and is mint green in color becoming pale green then blackish and gives rise to a majestic brown-black butterfly with a broad pale blue medial band crossing each wing pair that is broadest in the middle forming a triangle with the apex pointing toward the body. The underwing coloration shows the crimson lines near the toothed edge of the hind wing and a crimson spot just below the blue band.


Low-level rainforests. The caterpillars feed primarily on trees of the laurel family.


I found the caterpillar at my grandma's backyard on a young tree and started observing it. :3
