Butterfly populations are a very good indicator of the health of an area's ecosystem !!

   Graphium sarpedon is indigenous to southern S.E. Asia and eastern Austraila.
   They are a very active butterfly that moves quickly from flower to flower.
   They are found in urban areas, forests and woodlands. Although they prefer moist rainforest habitats, they have survived well in Sydney's suburbs.
   They are primarily an inhabitant of moist, low-level rain forests (below 1600 m (5000 ft)).
   In these elevations they are usually seen flying just above the tree canopy.
   The larvae of the common bluebottle feed on trees of the laurel family, which includes the cinnamon tree, and have expanded their range to include cinnamon tree plantations.
   In eastern Australia, they have adapted to a drier subtropical environment, and are commonly seen in suburban gardens in Queensland and New South Wales.
   Approx 16 sub species are distrubeted in different geographic regions.
   Males are known for their habit of feeding by the edges of puddles (puddling), often at roadsides.           Occasionally, as many as eight will be seen at the same puddle.
   They are also known to be attracted to animal droppings, carcasses and rotting insects.
   The Blue Triangle Butterfly's triangular shaped wings are a vibrant turquoise-blue with black around the edges. The Common Bluebottle has black dorsal wing sides and brown ventral wing sides.
   Both forewings and hindwings are marked by a central spot in the form of a blue or blue-green triangle, with apex pointing toward the body.
   The green Blue Triangle Butterfly larvae rest on the upperside of the leaves and are often difficult to see. If the plant is disturbed, you are more likely to smell them before you see them. (Many caterpillars in this family (Papilionidae) have an 'osmeterium', which looks like a fleshy horn that pops up from a slit behind their head and emits a strong smell.)
    In this species the osmeterium is yellow, but in other species it may be red.     
Diet: caterpillars feed primarily on the leaves of trees in the families Lauraceae, Myrtaceae, Sapotaceae, and Rutaceae.
Diet: adult common bluebottles feed on nectar from a variety of flowering herbs.
Avg. Wingspan: between 5.5 - 7.5 mm / 2.15 - 2.95"
Family: Papilionidae

The single biggest threat to butterfly survival is habitat destruction!!
